本文考虑地震地面运动的随机过程性、结构性态的弹塑性、结构破坏等级划分的模糊性以及未来地震发生的可能性,基于钢筋混凝土结构的破损度分析、模糊动力可靠性分析、震害预测和损失估计,提出了以可靠性为约束、以造价与损失期望之加权和为目标的钢筋混凝土结构优化设计简化方法。 This paper considers the stochastic process of seismic ground motion, the elasto-plasticity of structural behavior, the ambiguity of structural damage classification, and the possibility of future earthquakes. Based on the analysis of damage degree of reinforced concrete structure, fuzzy dynamic reliability analysis, earthquake damage prediction And the loss estimate, a simplified method for optimizing the design of reinforced concrete structures with reliability as the constraint and the weighted sum of cost and loss expectations as the goal is proposed.
