Title: Analytical and Experimental Studies of a Shearwall Stair Shaft
Author(s): L. Bogue Sandberg and Fred W. Beaufait
Publication: Special Publication

Abstract:The results of a study of the behavior of a shear wall stair shaft are summarized. Comparisons are made between deflections of a 1/24 scale Plexiglas model and predicted deflections from beam theory and finite element analyses. Both lateral loads and torsion are considered. Stair system stresses from a finite element analysis of a full scale, concrete prototype of the model are summarized. It is concluded that beam theory tends to over-estimate shear wall stiffness, and than an effort must be made to prevent damage to the stair system from severe shear wall deformations.
