DISPALCEMENT BASED SEISMIC EVALUATION OF R.C. FRAME-SHEAR WALL MODEL STRUCTURES

摘要：

By using capacity spectrum method which is related to the highly damped linear-elastic response spectra, the seismic behavior of a pseudo dynamic test model structure for R.C. frame-shear wall structure of main factory building in a heat-power plants is evaluated. The results show that some problems in capacity spectrum method, such as the equivalent linear system and equivalent viscous damping ratio etc. are to be improved further. After top displacement of structures is calculated, the displacement and force responses, location of crack and plastic hinge in every phase are analyzed according to nonlinear static push over analysis. The weak points and damage pattern of structures can be easily found by using this method. The results also show that the time history analysis method can be replaced by nonlinear static push over analysis to the displacement based seismic evaluation of R. C. structures.
