本文讨论了弹塑性强化结构的动力可靠性。文中引用了动力位移限界定理及动力安定性等概念,提出了直接计算单自由度结构可靠性下限的方法,并将该方法应用于简单抗震结构的计算。末尾给出一算例。 This paper discusses the dynamic reliability of an elasto-plastic reinforced structure. In this paper, the concepts of dynamic displacement limit and dynamic stability are cited, and a method for directly calculating the lower limit of reliability of a single degree of freedom structure is proposed. This method is applied to the calculation of simple seismic structures. An example is given at the end.
