Design

In the Design program mode only results for Ultimate Limit State loadcases will be displayed.

Moment My and/or Moment Mz and possible Axial force N

Necessary tensile- and possible compression reinforcement and adherent area, effective depth and compression zone height are shown as tables for the My and/or Mz moment.

If the current moment My or Mz is smaller than the moment of unintentional load eccentricity, according to the active concrete code, the latter will be the basis
of the design.

Comment: If both moments have been defined the design will be performed separately for each moment, which means that some bars can be used for bending in both directions at the same time. A calculation result like this should therefore be checked in the Analysis program mode in which a complete skew
calculation is being performed.

Axial force N

Necessary tensile/compression reinforcement and adherent area are shown as tables for current axial force.

The design is performed with consideration to unintentional load eccentricity according to the active concrete code.

Shear force Vy and/or Vz

Necessary shear reinforcement, adherent area, number of stirrup cuts and shear capacity of the concrete and reinforcement for shear forces Vy and/or Vare shown as tables.

Necessary shear reinforcement can, besides from current shear stress, also originate from rules according to the active concrete code such as minimum distance demands.

Note! If both shear forces have been defined the design will be performed in a way that uses the concrete capacity to its full in both directions.

Torque T

Required torsional reinforcement, reinforcement capacity and max torsional capacity are displayed in tables for torque Tx.

The result of the design is also shown graphically in the drawing area (as seen in the picture below).

Analysis

Loadcases in the Ultimate Limit State

The capacity is being calculated in accordance with the defined section forces.

Table results

  • Bending capacity
    Max moment MRy and adherent degree of utilization My / MRy, max. moment MRz and adherent degree of utilization Mz / MRz as well as efficient height and compression zone height are shown as tables. If stringer heights in shear calculation result in reduced moment capacity this reduced value is shown.
  • Shear capacity
    Max shear force VRdy, the capacity of the concrete Vcdy and adherent degree of utilization Vy / VRdy as well as max. shear force VRdz, the capacity of the concrete Vcdz as well as adherent degree of utilization Vz / VRdz are shown as tables.
    Note! If both shear forces have been defined the calculation will be performed in a way that uses the concrete capacity to its full in both directions.
  • Torsional capacity
    Max torque Tsd and associated utilization Tx / TRd as well as max torsional capacity and associated utilization are displayed as tabels.
  • Compression/Tension capacity
    Maximum compressed-/tensile axial force NRd and adherent degree of utilization / NRd are shown as tables.
