INELASTIC SEISMIC PERFORMANCE OF CONCRETE PRECAST 3D PANEL SYSTEM WITH DISCONTINUOUS SHEAR WALLS SUPPORTED ON RC FRAMES

摘要

In the present investigation, numerical dynamic analysis of a four-story building by scale factor of 1:2.35 is performed by ANSYS soft ware. The purpose of this article is to study the static and dynamical performance of the compound system which is consisted of pre-cast 3D panel system in upper floors and concrete frame in the ground floor. Through the analysis, dynamic properties of the structure, including natural frequencies and dynamic responses such as story displacement, story drift, story shear force and energy absorbed by each story under different seismic motion, in linear and nonlinear region are investigated. In addition, the distribution of tensile and compressive stress in concrete and tensile stress in reinforcement of various partition and also quality of generated cracks are estimated.The results of this study would be used in predicting the behavior of the structure under real earthquakes.
