摘要
本文将阶形变截面的框支剪力墙和落地剪力墙合并成一个阶形Timoshenko组合杆,壁式框架视为它的弹性地基,底层结构视为它的弹性支座,建立了水平振动方程,用常微分方程求解器解特征值问题,求得水平振动的自振周期和振型。
In this paper, firstly the cooperating system of shear wall, shear wall on flexible support and walled frame with stepped cross—section are simplified as a Timoshenko canti—lever beam on continuouselastic foundation with spring supports at the bottom end. Equations of horizontal vibration have been derived. Secondly, using the ODE (Ordinary Differential Equation) Solver, which is a program developed for solving various ODE, the fore five vibration frequencies and vibration modes have been obtained.
