Mechanical model for shear bearing capacity of buckling restrained steel plate shear walls
摘要
Abstract
A mechanical model for shear bearing capacity of buckling restrained steel plate shear walls was developed based on their stress distribution.It was considered that the shear bearing capacity was provided by the effective shear field of the panel and edge support members.A uniform formula for shear bearing capacity of buckling restrained steel plate shear walls was developed and validated by comparing with experimental and numerical results,and the specification.Further analysis shows that in range of practical aspect ratios of 0.5-2.0,the effective shear area varies in 20%-55% of the whole panel of the shear walls connected with only beams,and the bearing capacity is reduced by 10%-52% compared with that of the walls connected with both beams and columns.Its safety margin is lower than that of the walls connected with beams and columns and the walls with added side columns because of tearing at the corners in advance.The feasibility of adding columns at both vertical edges of the walls connected only with beams was illustrated by an example.The requirement of side-column section areas was proposed to ensure an effective shear stress field in whole panel.关键词
