  • Fix: In the steel module, for a fully supported flange in a single symmetric cross section the calculation of critical load considering flexural-torsional buckling produced a numerical error causing related code check to be omitted for certain column segments (110267).
  • Fix: For the special case of a single symmetrical section continually supported out of the frame plane at one edge, the critical lateral torsional buckling moment Mcr was wrongly calculated which is corrected (case 110342).

  • Fix: Some values has been slightly changed due to an updated certificate for Kerto beams (case 116807).
  • Fix: The program could not find a solution for the critical lateral torsional buckling  Mcr for a member due to a numerical problem which resulted in a small moment where it should have been zero. A solution for this have been implemented (case 116811).

  • Fix: In the design check Torsional and flexural buckling out of the frame plane for steel sections a 2nd axial force where mixed with 1th order moment. In this check only 1th order section forces should be used which is corrected (case 118203).
  • Fix: As imperfections only has to be considered in the most dangerous direction and  according to Eurocode Helpdesk this is the direction with the highest utilization some examples that before presented a biaxial check now instead displays an information that no biaxial check is needed (case 119439).
  • Fix: When calculating in the Serviceability Limit State with a 1th order analysis stresses was done with 1th order section forces which has been corrected  (case 119557).

  • Fix: Fixed a program crash in the window for unsupported joints, viewed with absolute values (Case 81530).

Frame Analysis 6.4


Released: 2018-12-05

  • Fix: Elements with compressive normal force are now treated as columns when determining min. reinforcement, i.e. max spacing for stirrups (Case 13047).
  • Fix: The moment capacity in the stress check should be reduced when the shear force is larger than 50% of the shear capacity.  For the case combined moment and axial force the total moment capacity was conservatively reduced instead of only the moment capacity from the part of the section used for calculating shear capacity which is corrected (case 63058).
  • Fix: When the program calculates initial reinforcement minimum requirements from the code are considered. If user defined reinforcement does not follow these requirements a warning has been added (case 67663).
  • Fix: The last row of the project comment falls away in the printout (Case 69047).
  • Fix: The lateral torsional buckling capacity where for some cases underestimated which has been corrected. It applies to elements with a support moment at one or both ends end if the support moment is larger than the span moment (case 69172).
  • Fix: Calculation of capacity according to the stiffness method (EN1992-1-1 5.8.7)  requires  a reinforcement area As > 0.002 Ac (case 70237).

  • Fix: For rotational springs the grade was wrongly displayed in some cases which is corrected (case 71856).


Released: 2018-07-27

  • Fix: Slightly angled (and very short) beam elements could lure Frame to incorrectly displaying the warning 'No serviceability Limit loadcase calculated or calculation not finished' in the result tables (Case 65784).
  • Fix: For single symmetrical I-sections the program used the elastic section modulus instead of the plastic for sections in section class 1 and 2 which is corrected (case 65893).
  • Fix: An error  concerning the calculation of the plastic section modulus with regard to the weak direction for non-standard U-sections  has been corrected (case 65898).
  • Fix: An HSQ section was wrongly set to rolled  instead of welded which made the section class calculation  incorrect (case 66122).
  • Fix: For user defined steel sections the program assumed welded section which also is default. If the construction method was changed to cold-formed the calculation was wrong and the capacity somewhat overestimated which is corrected (66957).


Released: 2018-04-06

  • Fix: Made sure the gamma values are correctly updated when you choose to edit an existing (user defined) material (Case 64785).

Released: 2018-02-14

  • Fix: The 2ord moment for timber structures was somewhat overestimated as the program did not recognize the load-duration for the basic loadcases when calculting the E-modulus. All load cases where then choosen as permanent (case 62544).
  • Fix: Changing section and material from concrete to steel could sometimes cause memory error resulting in program freeze (Case 62932).
  • Fix: The dialog for "Define code" did not allow selection of a annex tied to a license that was all consumed (Case 63008).
  • Fix : For Swedish national annex, the check for minimum concrete grade in regards to current exposue class (table E.1N) is removed (Case 63212).

Released: 2017-11-09

  • Fix: The current buckling lengths are from now on displayed in the Capacity window also for concrete members (Case 51348).
  • Fix: The compression check for the Serviceability Limit State displayed in the code check window where for an example shown for the wrong load case which is corrected (Case 52146).

  • Fix: For plate sections, the design results where reset to zero when the calculation for minimum reinforcement failed (case 49269).
  • Fix: Renamed reinforcement material B500B to K500C-T for Swedish national annex (Case 49267).


Released: 2017-03-14

  • New: The 'Define code' windows now allows for choosing 'no code' for the design modules, thus releasing that license for others to use when connecting to a license server (Case 33733).
  • Fix: Frame froze up while looking for calculation convergence (Case 46328).
  • Fix: Removed warning that sometimes popped up when double-clicking on fra-files saying 'There was a problem while sending the command to the program' (Case 46914).
  • Fix: The kcr factor used in shear test for timber structures was wrongly set to 0.8 for the Swedish Annex when code value was chosen. An option for structures exposed to sun and rain according to EKS 10 has been added which results in kcr=0.67 if chosen, otherwise 1.0 (case 47534).


Released: 2016-11-08

  • Fix: Concrete calculation in 'code independent mode' used incorrect values for E-modulus (Case 45369).
  • Fix: When designing according to 2nd order theory the buckling length in the plane of the frame is not used unless to calculate the interaction factors kzy, kyz. Due to a change made recently this buckling length was in some cases wrong resulting in wrong integration factors which has been corrected. (case 45636)
  • Fix: When a 2nd order design is performed the buckling length in the plane of the frame is normally not needed except to calculate the interaction factors kyz and kzy. If a unrealistically large buckling length where defined this resulted in negative integration factors which then where chosen to zero resulting in no contribution from the moment in the interaction formula. This has been adjusted and if the integration factors are found to be negative they are from now on chosen to the maximum value 1.5 (Case 45643).


Released: 2016-10-13

  • Fix: Added an extended error message for when all licenses are consumed. The extra message contains the current users.


Released: 2016-09-06

  • ■    Fix: When the design is made according to 2nd order theory no buckling length with regard to flexural buckling in the frames plan is normally required. However when the kyz and kzy factors involved in the flexural buckling out of the frame plane are calculated this buckling length is required. Normally this buckling length as default is the same as the member length but can be changed by the user. If the unsupported joints are used e.g. for trusses the member length is normally much larger than the buckling length and therefore the program from now on will choose the largest distance between two nodes as a default value for the buckling length when a 2nd order design is performed (Case 38856).
  • Fix: The density for glulam qualities changed to mean density (Case 40928).
  • Fix: The profile KKR 220x220-10 had to small thickness which has been corrected (Case 41616).
  • Fix: The material data in the printout for glulam materials was partly incorrect. The calculation and results was however correct  (Case 42826).
  • Fix: A number of  VKR profiles was recently wrongly added as KKR profiles. The ones available as KKR has been corrected and the rest marked as not available (Case 43777).
  • Fix: A number of VKR and KKR profiles from SS-EN 10210 and SS-EN 10219 has been added. Some values for VKR and KKR profiles added a long time ago has been slightly changed which has been corrected (Case 43885).
  • Fix: A number of VKR and KKR profiles from SS-EN 10210 and SS-EN 10219 has been added. Some values for VKR and KKR profiles added a long time ago has been slightly changed which has been corrected (Case 43885).


Released: 2016-06-20

  • Fix: For load wizards, the generate button didn't create a dead load which is corrected. (Case 31822).
  • Fix: Added a check for web shear compression failure (case 40321).
  • Fix: The elastic section modulus was used for U-sections when calculating bending around z-axis in sections class 1 & 2, now plastic section modulus is used instead. (Case 40405).


Released: 2016-04-18

  • Fix: Reworked the tables in Result Mode making sure all data is shown correctly (Case 40112, 40116, 40123).


Released: 2016-04-13

  • Fix: For steel design the program in some cases wrongly uses a lower initial bow imperfection value from an earlier code instead of the values in EC2 table 5.1. This affects design based on a 2nd order analysis which means that the capacity in those cases could be somewhat overestimated. A design based on a 1th order analysis is not affected (Case 39426).
  • Fix: The initial bow imperfection value for each member is now displayed in the print output for Concrete, Steel and Timber (Case 39908).


Released: 2015-12-22

  • Fix: A warning about defining an effective creep value should not be displayed either when an effective creep value or a dependency to a SLS loadcase with creep is defined for every ULS loadcases (case 35455).


Released: 2015-11-04

  • Fix: The E-modulus was not reduced by the effective creep value for Accidental ULS loadcases which is corrected. When switching between ordinary and Accidental type for ULS loadcases the effective creep value was set to zero which is corrected. (Case 34831).
  • Fix: A warning about the importance to define an effective creep value according to EC2 5.8.4 (1) in second order analysis and design has been added (Case 35032).


Released: 2015-10-28

  • Fix: When license server ran out of optional licenses such as design codes and wizard Frame when into lockdown mode incorrectly (Case 34497).


Released: 2015-10-21

  • Fix: A number of KKR-profiles recently added where by mistake implemented with ten times to large elastic and plastic section modulus which has been corrected. This problem affects the following profiles (Case 34365):
    100x60x8, 120x60x8, 120x60x10, 120x80x10, 140x80x5, 140x80x6.3, 140x80x8, 140x80x10, 150x100x12, 150x100x12.5, 160x80x10, 160x80x12, 160x80x12.5, 180x100x4, 180x100x5, 180x100x6.3, 180x100x12, 180x100x12.5, 200x100x4, 200x100x12, 200x100x16, 200x120x6.3, 200x120x12, 200x120x12.5, 250x150x12, 250x150x12.5, 250x150x16, 260x180x6, 260x180x6.3, 260x180x8, 260x180x10, 260x180x12, 260x180x12.5, 260x180x16, 300x200x12, 300x200x16, 400x200x12, 400x200x16, 450x250x8, 450x250x10, 450x250x12, 450x250x12.5, 450x250x16, 500x300x10, 500x300x12, 500x300x12.5, 500x300x16, 500x300x20.

  • English is the the default language for new installations (re-install keeps old setting).
  • Concrete design (EU): Fixed a discrepancy between the utilization colouring on the canvas compared with the code check window.
  • Reworked some of the input control concerning deflections causing the "division with zero" warning to incorrectly appear.
  • Program settings are now saved in the current user folder rather than a common folder.
  • Added increased mouse control for zoom (mouse wheel scroll= zoom in/out, mouse wheel click + drag = pan, mouse wheel double click = zoom extent).

  • Fixed an issue with the database files not being copied when changing target folder for the section and material databases.


Released: 2013-03-15

  • The load wizards with regard to EC is now implemented which means that design is now also possible for the special steel truss sections double L- and double U-profiles.
  • If the load situation is such that no section forces can be calculated an error message is from now on displayed to inform about this.
  • Steel:   For some newly added symmetric KKR profiles the second moment of inertia was 100 times to large which has been corrected.

  • ■    Steel: Fixed bug where Nx along the element was in some cases neglected when calculating interaction variables.
  • ■    Changed the name of the user defined steel material to mirror given material parameter.


Released: 2012-12-21

  • Updated the installation file to accomodate the new StruSoft Installer.
  • In some cases it was not possible to change language if the program was not installed by an administrator which is corrected.
  • Steel: An error in some cases causing the integration factor kzy to be slightly wrong has been corrected.
  • Steel: For an example no solution for lateral-torsional buckling could be found which is corrected.
  • Steel: The formula calculation the integration factor kzz has been slightly changed in the code EN 1993-1-1 which is corrected.
  • Concrete: A problem causing the shear capacity being zero at the very end of a member if the member length and the shear reinforcement area differ by a very small distance has been corrected.
  • Concrete: The warning about to large distance between shear links was not always displayed because the error list was not reset when a new calculation started which is corrected.
  • Concrete: A problem causing the reinforcement to be drawn outside the member if the design option “Detailed” was chosen is corrected.
  • Timber: The flexural buckling check when calculating according to 2nd order theory is changed by removing the exponent on the relation between the axial force and the axial force capacity.

  • Fixed a bug that blocked the material choice dialog from popping up when clicked upon in the reinforcement grid for stirrups.


Released: 2012-10-02

  • Updated the way in which the program handles the layout file for the print engine.
  • Updated the module responsible for saving program settings and search paths.


Released: 2012-09-18

  • For short time loadcases the E-modulus for timber members should not be reduced by the kdef value considering creep which is corrected.
  • In the Timber module the value of the kh factor according to EN 1995-1-1 3.2 for sections in tension was wrong which has been corrected.


Released: 2012-09-07

  • It was not possible to change the resolution on the drawing area which is corrected.
  • For design according to the Swedish steel code BSK in some cases a wrong axial force was used for the bucklimg check out of the frame plane which is corrected.
  • The lateral torsional buckling capacity was wrong for cantilever members supported at the tension side which has been corrected.
  • In some cases the lateral torsional buckling capacity was lower for members supported at the tension side than for non-supported members. In this case the latter capacity will be used.
  • The steel design strength for the Swedish annex is from now on calculated according to EN 10025-2 which means that the strength is depended on the thickness of the section parts.
  • The steel H-sections could not be saved properly which is corrected.
  • The section lists for hole profiles VKR and KKR has been revised. Profiles which are no longer available in the standard selection has been marked with an indication and some new profiles has been added.
  • A warning will be displayed if unrealistic values for the creep- or shrinkage factor is defined.
  • A problem to open files defined with the gerber macro has been solved.
  • Updated the way in which user specific settings and data is stored.

  • The section class for HSQ beams was wrongly set to section class 4 if the construction method was set to warm-rolled which is corrected.
  • The safety factor gM2 has been removed from the program as it is not used.
  • The shear capacity fvk for glulam qualities L40c and L40s has been increased from 2.7 kPa to 3.5 kPa.
  • For 2nd order steel design with a low axial force in a member a pure “Lateral torsional buckling check” could be more dangerous than the “Flexural torsional and lateral torsional buckling check” and therefore this former check has been added as well.
  • For I- and U-sections a wrong section class was sometimes presented in the Section class window although the calculation was correct.
  • The web-buckling check for slender steel sections was wrong and has been corrected.
  • For 2nd order design the interaction factors kij are maximized to 1.5 as otherwise unrealistic values could be calculated depending on the buckling length chosen as the full member length in the frame plane.
  • The calculation of the critical lateral torsional moment Mcr for a constant or linear varying moment distribution that does not change sign along the member was not dependent on the load level. This has been changed so when the load level is at top the buckling length is increased with 2h and when it is at bottom the length is decreased with 0.5h.
  • For Norwegian annex the gM values has been changed to 1.25 for solid timber and 1.15 for glued laminated timber.
