考虑环境作用引起的结构耐久性损伤对结构构件抗力的影响,通过对抗力基本参数劣化规律的分析,建立了混凝土结构的抗力衰减模型,并分析了抗力的统计参数;在当前建筑结构荷载与抗力的调查统计分析基础上,提出了结构的动态可靠性分析方法。以钢筋混凝土受弯构件为例,具体分析了构件抗力平均值和结构可靠度随时间的变化规律,为建立考虑结构抗力衰减的可靠度设计方法奠定了基础。
Considering the influence of structural durability damage caused by environment on the resistance of structural members, the paper analyzes the deterioration of basic parameters of resistance and establishes the model of resistance attenuation of concrete structure, and analyzes the statistical parameters of resistance. In the current structure load and resistance Based on the survey statistical analysis, put forward the structure of the dynamic reliability analysis. Taking reinforced concrete flexural members as an example, the changing law of average value of structural resistance and structural reliability with time is analyzed in detail, which lays the foundation for establishing the reliability design method considering the structural resistance attenuation.
