摘要
提出了一种求解的非线性地震反应的二阶矩阵扰动振型叠加方法,通过与Wilsonθ法的比较,验证了它的高效性与可行性。
The mode superposition method with the second order matrix perturbation technique for calculating nonlinear seismic response of structure is presented.The comparison between the proposed method and wilson θ method is made by numerical examples,the high effectiveness and feasibility of the proposed method are verified.
