摘要
本文用沿高度方向分段连续化的方法,对沿高度方向为阶形变截面、在平面内布置复杂、需要部分考虑楼板变形的框架-剪力墙-薄壁筒结构,建立了其水平振动的弯扭耦连振动方程组。用常微分方程求解器(COLSYS)求解其自振频率及相应的振型,为复杂结构提供一种可用于设计的动力计算简化方法。
In this paper, firstly using the piecewise continuum, technique for the structures, the coupled differential equations of horizontal vibration for the tall building frame-shear wall-thin walled member systems with stepped parameters and with floor slab's deformation considered have been derived.Secondly, using the Ordinary Differential Equation Solver, which is a program developed for solving various ODE problems including cigen-pro-blems, the vibrational frequencies and vibrational modes have been obtained.
