非均质地基非线性地震反应的半解析算法
|
摘要
运用动态应力应变关系及其推广的Masing加卸载准则,考虑土体在地震等产生的不规则加载条件下的非线性滞回特征,将增量法与相应场地地震线性反应解析相结合,对剪切模量是其深度的某一幂函数的非均质地基,提出了该动力非线性方程的半解析时域算法。算例结果与其相应的线性结果对比,发现最大位移与最大加速度沿深度的变化规律基本相同。
Dynamic constitutive relationship,together with the extended Masing's rules,is employed to account for nonlinear hysteretic property of soil material under transient or cyclic loadings.Incremental method and the general solution to linear seismic response of vertically non-homogeneous foundations with power function shear modulus are combined to develop a seimi-(analytic) calculating technique for dynamic nonlinear problem.The comparison results of the calculation examples indicate that this algorithm is rational and feasible.2 figs,6 refs.
