PART 1: Evaluation of Maximum Drift Demand for Seismic Performance Assessment of RC Buildings

The main objective of this research project is to residual deformation and collapse mechanism of structural system and to assess the seismic demand of this system. In this study three major works are developed: a. Develop a physical-based inelastic hysteretic model which contains stiffness and strength degradation, pinching and residual deformation, b. Based on the proposed model the seismic demands of structural system are examined. Emphasis is concentrated on the study of MDOF system, c. Conduct the shaking table test of collapse. Examine the collapse behavior and develop the hysteretic model which included the collapse mechanism. Through this study three research papers were generated and they are listed as follows: 1.
