摘要
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。
A feasible method of optimum design for nonlinear reinforced concrete aseismic structures is presented in this paper based on the damage index analysis, fuzzy dynamic reliability analysis, failure prediction and loss assessment. In which, the stochastic process of seismic ground motion, the elastoplasticity of reinforced concrete structures, the fuzziness of structural damage classification and the probability of future earthquake occurrence are taken into consideration. The weighted sum of initial construction cost and expected failure loss is taken as the objective function, and the reliability is taken as the constraint.
