Seismic Performance Evaluation of Steel Shear Wall by Equivalent Truss Approach Modeling
Steel plate shear wall is one of the efficient and economical lateral resistance systems which has been implemented in various structures, located in highly seismic prone areas. Infill steel panel is surrounded by beams and columns as boundary elements, to provide sufficient lateral stiffness of structure. This study presents verification between prior studies and computer modeling of various structures equipped by steel shear walls based on the equivalent truss element method. Furthermore the efficiency of the aforementioned system is compared with special brace frame in terms of maximum displacement, base shear, axial force, rotation of critical columns and material usage by aid of time history analysis. The results show that existence of shear wall as a lateral resistance system decreases maximum displacement, base shear, axial force, torsion of critical columns about 25 %, 60%, 50% and 80% respectively, compared with structure equipped by special steel concentrically braced frame. Both systems passed the code requirements for maximum displacement, but application of steel plate shear wall reduced total weight of structural steel elements around 21%. Furthermore, results reveal that equivalent truss element is a reliable method for modeling shear wall element in computer modeling since results are verified by previous studies as well.
