考虑地震作用和结构参数的随机性，建立了钢筋砼结构药非线性随机动力学模型。文中导出了随机结构动力分析的非线性随机有限元法的增量列式，并据此对多层钢筋砼结构进行了弹塑性随机地震响应分析。计算结果与该建筑物的实际震害作了对比，效果良好。还讨论了动力模型中随机变量对响应量的影响。
Taking into account the randomness of seismic effects and structural parameters, a nonlinear stochastic dynamic model of reinforced concrete structures was established. In this paper, an incremental formulation of the nonlinear stochastic finite element method for the dynamic analysis of stochastic structures is derived. Based on this, the elasto-plastic random seismic response analysis of the multi-layer reinforced concrete structures is performed. The calculation results are compared with the actual earthquake damage of the building and the effect is good. The influence of random variables on response in dynamic models is also discussed.
