本文提出了大震裂度下多层剪切型结构基于首次超越和累积损伤双重破坏准则的抗震可靠性的计算方法。文中,在导出了多层剪切型滞后结构,在大震烈度下相对层位移最大延性反应的概率分布函数和层滞后吸收能量的概率密度函数的基础上,得到了建筑结构基于双重破坏准则抗震可靠性的计算公式。据此计算的工程实例的结果表明,本文方法具有较好的精度。
This paper presents the calculation method for seismic reliability of multi-layer shearing structures based on the double failure criterion of first-pass overgrowth and cumulative damage under large-shear strength. In this paper, a multi-layer shear-type hysteretic structure is derived. Based on the probability distribution function of the maximum ductile response of the relative layer displacement and the probability density function of the absorbed energy of the layer lag, the building structure is based on the double failure criterion. Reliability calculation formula. The results of the engineering examples calculated according to this result show that this method has better accuracy.
