Abstract
 

The latest research on determining maximum allowable displacements at the top of a shear wall (or maximum Drift) has contributed considerably to the improvement of concrete structures. Aiming at limiting maximum displacement, various investigators and seismic codes use values ranging from H/50 to H/2000, (H=building height). Difference shows considerable uncertainty in these limits. This article evaluates maximum allowable drift and provides general formulae for constant and variable stiffness shear walls by using FEM along with structural dynamics and reinforced concrete design considering cracked shear wall sections suggested by UBC and ACI. A comparison is made with various codes.
