Methodology
The wall group shown below will be used to illustrate the method adopted.
Calculation of shear capacity Vu for the wall group
Every wall segment will be considered in turn. For each wall segment, the calculation of Vu will be made according to the equations in 11.5.3, 11.5.4 and 11.5.5. The calculation will be performed in the following manner:
Assuming a shear direction parallel to the x-axis:
- tw will be taken as the thickness of wall (t) immaterial of the orientation of the wall segment.
- Lw will be the length of the wall resolved in the direction of shear (e.g., LW (b) for wall B above and 0 for wall A).
The value of Vu for the whole cross-section is the sum of the values of Vu obtained for every segment.
