Shear Wall Design#

The task offers the possibility to perform the (preliminary) design for shear walls.

This chapter of the documentation focuses on the user input with the graphical user interface.

Design Options#

  1. Select between the following two design methods:

  2. Choose which Design State is applied:

    • Defaults to Automatic, where the design state and the material safety factors are determined by the load combination type.

    • It is possible specify the design state independently from the load combination type.

  3. Additionally, you can override the Material Safety Coefficients for concrete and reinforcement. Without manual override, the values are taken from the .ini file of the selected design code for the project.

Shear Wall Selection#

Select the walls for the shear design.

Note

The General Design Method requires the new cross section type Shear Wall.

Hint

  • Use the filter above to facilitate the selection of walls, e.g., all walls associated with a building core.

  • A right-click menu allows to (de-)select all rows at once

Preview#

The interactive viewer shows the selected wall with its dimensions, orientation in the project and the assigned cross section, if available.

The local coordinate system belongs to the design element and its cross section, indicating the location of the edge zones.

Load Case Selection#

Select the load cases used in the design for shear walls. The load case table is filtered for relevant load cases containing design element results. By definition, only load cases for the superpositioning of normal force, shear forces and bending moments, are considered for the design and automatically selected.

The task supports the following design combinations:

(D)

ULS fundamental combination

(A)

ULS accidental combination

(E)

ULS seismic combination

Tab Design#

Depending on the choice under Tab General ‣ Design Options, this tab presents itself differently and allows for design method specific input.

Compression and Tension Method#

GUI Task Shear Wall Design - Design Tab for |CTM|

GUI Task Shear Wall Design - Design Tab for C&T-Method#

Design Settings#

Set the general design parameters by defining the maximum reinforcement ratio for the individual edge zones.

Shear Wall Settings#

Define the edge zones for each wall by determining the minimum and maximum length for each zone.

Parameter

Description

Default

Range

Min

Minimum length: Starting Point for iteration of C&T-Method

0 %

0-50 %

Max

Maximum length: End point for iteration of the C&T-Method

50 %

0-50 %

Note

Setting minimum and maximum length to the same value results in a fixed edge zone length.

Hint

  • It is possible to copy-paste cell values with CTRL + C and CTRL + V

  • To copy multiple values, make sure to match ranges for source and target

Preview#

The interactive viewer shows the selected wall with its dimensions, orientation in the project and the assigned cross section, if available.

The local coordinate system belongs to the design element and its cross section, indicating the location of the edge zones.

By definition Edge Zone A is located in positive local z-direction.
