摘要
根据硫酸盐腐蚀和持续荷载共同作用下的混凝土抗压强度与钢筋抗拉强度时变模型,建立了硫酸盐侵蚀环境下混凝土受弯构件抗力随机模型,以服役状态混凝土楼板为研究对象,采用可靠性理论,使用当量正态化的验算点法对可靠性指标进行了计算,分析了恒、活荷载和硫酸盐共同作用下钢筋混凝土结构受弯构件的耐久性。
According to the concrete cube compressive strength and the reinforcement tensile strength time-varying model which were under the sulfate corrosion and sustained load,the paper built the stochastic resistance model of the concrete bending specimens in the sulfate solution,took the floor in the service as the study object,based on the reliability theory,calculated the reliability index by checking point method,analyzed the durability of the reinforced concrete bendings which subjected to the sulfate attack,and assessed the durability of the floor by using the resistance model.
