摘　　要：本文通过建立考虑材料应变强化效应的钢杆件空间受力非线性模型，导出了带缺陷空间钢框架结构在使用历程中的承载性能分析方法，为这类在役钢结构的技术性能评估、维护及加固提供了可靠的理论依据、计算方法及程序。Abstract A 3 dimensional nonlinear mechanical model of steel members considering the effects of yielding and strain hardening of material is derived in the paper. The theory for the analysis of the behavior of steel frames with imperfections and in service is established. This theory makes the appraisal, repair and maintenance of the steel frames with imperfection having a sound theoretical bases and offers a reliable computation method and program as well.
