University of Qom Civil Infrastructure Researches 2783-140X 2 1 2016 08 22 Presenting a simple model to nonlinear analysis of thin steel plate shear wall Presenting a simple model to nonlinear analysis of thin steel plate shear wall 1 12 749 10.22091/cer.2016.749 FA Mohamad Ghasem Vetr Assistant Professor, Structural Engineering Research Center, International Institute of Earthquake Engineering and Seismology Ali Ghamari Lecturer, Faculty of Engineering, Islamic Azad University of Darrehshahr Journal Article 2016 02 01 Despite of the adequate performance of thin Steel Plate Shear Wall (SPSW) in last earthquakes and also during studies performed in the laboratories in all of the world, some problems and some defects such as lake of capability of commercial civil engineering software for modeling of the buckling and post buckling under lateral loading, lake of national Cod in this field of steel structures, have made an obstacle about its expanding in civil projects. Based on these mentioned problems, in this paper, a new and innovative model (method) is presented that the steel plate replaced with diagonal single brace member. This proposed method decrease analysis time due to decreased elements comparing with other presented methods. In other hand, the proposed method (model) provide a capability for static analysis and dynamic analysis of structures. Comparing the experimentally results with the proposed method shows a good convergence on stiffness and ultimate strength.
