The Analysis Of The Seismic Performance Of Steel Reinforced Concrete Structure

The response spectrum analysis, nonlinear static analysis, dynamic analysis of theseismic performance of structures were analyzed and compared in the paper by usingthe models of steel reinforced concrete structures and reinforced concrete framestructures. First of all, the seismic performance was compared by periodic of structure,deformation and dynamic characteristics after analyzing the response spectrum.Secondly, the period of structure, the curve of base shear-top deformation, the analyzeof performing point and the change of plastic hinges were discussed in the paper toanalyze the two structures static elastic-plastic performent. Lastly, the curves of toppoint’s time travel curve, the interlayer displacement, inter-story drift angle under thedynamic load by analyzing the two models’ dynamic time history performent.Through this article, we can get through the three methods of analysis to thestructure modeling analysis, the relevant deformation characteristics of the twostructures were similar, but the seismic performance difference is obvious. Throughresponse spectrum analysis, we can get good ductility of steel reinforced concretestructure, the lateral stiffness big, determine the weak spot of the structure. Property canbe obtained through the static elastoplastic analysis, as well as the change of the plastichinge. Through dynamic time history analysis, we can get the structure under seismicdisplacement between layers, interlayer displacement Angle, vertex displacement timehistory curve, base shear curve, determine the seismic performance of the structure.
