摘要
系统地分析了钢筋混凝土结构在长期环境侵蚀作用下强度、动弹性模量的变化规律．指出了现行混凝土设计规范中可靠度分析模型的缺陷，并利用动态可靠度模型以及变形破坏准则研究了时间因素对ＲＣ框架结构抗震可靠度的影响．
In this paper, the authors analyze systematically the variation of strength and dynamic modulus of RC structures caused by long time environmental excursion. The shortcomings of the analytical model of reliability existing in the current code of concrete structures are put forward. The influence of time factor on the earthquake resistant reliability of RC frame structures is studied by use of dynamic reliability model and deformation damage criterion .
