摘要
本文利用塑性理论建立了可用于结构非弹性动力分析的钢筋混凝土杆件多维恢复力模型，该模型考虑了钢筋混凝土的三折线型滞回规则和刚度退化性能。编制了相应的计算机分析程序，对空间框架结构进行了非弹性地震反应计算，用试验结果检验了模型的合理性。
In order to stUdy the inelastic dynamic response of three-dimensional reinforcedconceive frames, the multi-dimensional restoring force model is extended from one-dimesionaldegrading type of trilinear hysteresis rule by using the associated plastic flow rule and Mroz'shardening rule. An algorithm is designed for space reinforced concrete frames. The rationality ofthis model and the program are verified with the test results of the reinforced concrete framewhich has plane eccentricities by non-coincidence of centers of mass and stickness.
