AN IMPROVED MULTI-VERTICAL-TRUSS-ELEMENT MODEL OF SHEAR WALL AND ITS APPLICATION

Three methods for calculating shear deformation in the multi-vertical-truss-element model are discussed in detail and a comparison is made. A more reasonable derivation process of the element stiffness matrix is put forward. Combined with hysteretic axial model and hysteretic shear model, nonlinear analysis of shear wall is performed. An example is calculated and compared with test results, which shows that the model offers results with good accuracy.
