ELASTIC BUCKLING ANALYSIS OF STEEL PLATE SHEAR WALL WITH ELASTIC RESTRAINT OF TWO SIDES UNDER THE ACTION OF SHEAR AND COMPRESSION FORCE

Surrounding members(i.e. beams and columns) were assumed to supply simply supported edges for steelplate shear wall in the design of steel plate shear wall, and then the embedded coefficient of 1. 23 was introduced to consider the restriction effect of surrounding members. The effect of rigidities of the surrounding members was not considered in the design process. A finite element analysis was carried out to investigate the elastic buckling of steel plate shear wall under shear and compression load. It was found that the factor , that is ratio of rotational rigidity of the surrounding members and bending rigidity of the steel plate, was a good factor to measure precisely the elastic restraints of surrounding members to the shear wall. Based on computing data from more than 400 models, the equation of shear buckling coefficients was developed for steel plate shear wall with elastic restraint of two sides.
