层状基础的动力响应分析
Analysis of the dynamic response on stratified foundations
【摘要】 基于剪切梁理论,利用振型叠加法及振型函数正交性,求得体系的参与系数及稳态动力响应的封闭型解析式;最后针对算例,利用龙格—库塔法得出土层的最大响应图(位移、剪应力、加速度)。
【Abstract】 Based on shear beam theory,the closed-form analytical expressions are derived for participation factors and steady-state dynamic response functions by using the modal-superposition method and orthogonal property of modal displacements.Finally,using Runge-Kutta method,the maximum responses(including the displacement,the acceleration,and the shear stress) are obtained.
