考虑荷载作用下抗力时变特性的沿海钢筋混凝土结构可靠度分析
Analysis on reliability of reinforced concrete structures in marine environment considering resistance time-varying characteristic
摘要
Abstract
In this paper, considered the complexity of the influence factors on damage of steel concrete structure under the marine environment, a Chloride ions erosion model and a steel erosion model were set up. The resistance of RC members and the applied load were considered as random processes and transformed into random variables for annual extreme values in design periods. JC method was adopted to calculate the reliability index of structure. The reliability analyzing method which considering RC members time-varying characteristic under loads was established for reinforced concrete structures in marine environment. A piled wharf example were calculated to show how to calculate the structural reliability considered the effect of loads, and to make comparisons considered the effect of the loads or not considered.关键词
