2 5 clear to strength steel 5 12 rather than the designed 5 10 bending strength of the section has been reduced by about 16.
Using table 4 the wall can be adequately reinforced using no.
A 20m high 3 5m long shear wall is acting as both a lateral and vertical support to a 4 storey building.
Design is similar to a rc column breadth equal to thickness of wall and depth equal to 1m.
Two equations are developed in this section for determining the thickness reinforcement required to resist the bending moment in the retaining wall components stem toe and heel.
Reinforced concrete stocky wall is where the effective height he divided by the thickness h does not exceed 15 for a braced wall and 10 for an unbraced wall.
The hand solution is used for a detailed comparison with the analysis and design results of the engineering software program spwall.
