摘要
本文以概率分析及安定下限定理的分析方法,从三个方面对钢结构的安定问题进行了研究。结果表明:在重复变化荷载作用下,在常用结构参数范围内,材料满足塑性设计要求的延性和应变硬化性能时,按简单塑性理论设计的钢结构不会发生累极破坏和交变屈服破坏。
The stability problems of steel structure are studied using the method of probability analysis and stability lower bound theorem from three respects. It is shown that if the material meets the plastic design requirement in ductility and strain-hardening behaviour, the cumulative collapse and alternate yield failure of steel structure which is designed according to simple plastic theory does not occur under repeated and variable loading and within the extent of common structure parameters.
