The Reliability Research of Steel Plate Shear Wall Based on APDL

Abstract

Abstract: The models of un-stiffened, cross stiffened and diagonal stiffened are established by the APDL language of ANSYS, then their reliabilities of stochastic finite element are researched. The result shows that, under the equal seismic forces, the reliability of the three models from childhood in order as is the un-stiffened, the cross stiffened and the diagonal stiffened. And the vertical pressure is the most effective factor toward the three models. Recently years, the study about the steel plate shear wall at home and abroad is almost the research [1,2] of experience and hysteretic performance by the theory combined with experiences. Xianzeng Li [3], who discussed the feasibility of thin steel plate shear wall which is used in the seismic area, studied the stress structure feature and seismic feature of the thin steel plate shear wall under the drab and cyclic loads by finite element. The shear performance under one-way load and the hysteretic performance of the diagonal stiffened were researched deeply by Chunhua Cao [4,5], and the result shows that it’s an excellent part of resisting lateral force with full stability lag circle and high security reserve. In this text, the analysis about the reliability of steel plate spear wall is completed.
