摘　　要：进行钢框架弹塑性静动力分析时,各单元恢复为模型的选用直接影响分析结果的精度.作者对钢框架的柱、梁及节点板域单元的恢复力特性进行了讨论分析,给出了简化的线性单元恢复力模型,并给出了拐点的处理方法.算例分析表明本文的恢复力模型是可靠的.When making the elasto-plastic static and dynamic analysis of steel frame, it is important for accurate analysis to select the suitable restoring force model of elements. The restoring force characteristics of the steel frame elements are discussed, and the linear restoring force models of elements are established. The calculating examples verify that the propsed models are reliable.
