There is a question from a fellow structural engineer about a concrete wall slenderness ratio. It is an end wall supporting gable roof, 14m long. The height is 12m to ridge and 8m to eave. The wall is 8” thick with double reinforcement. Further, the wall is simply supported at top and bottom, also there is a concrete floor (lateral support) at the 3m height. It is apparently a slender wall and exceeds the limit without deflection check. He check and strength and deflection. They are okay.
The question is whether the wall is too slender? Can he use the mean value as the wall height? any other things he should check?
