| 中文摘要: |
| 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,在平面内为任意斜向布置的框架-剪力墙-薄壁筒协同工作体系,建立了弯扭耦连的振动方程,用常微分方程求解器(COLSYS)求解了自振频率及相应的振型。 |
| 英文摘要: |
| In this paper, firstly using the continuum technique for floor slabs, the differential equations of horizontal vibration for a tall building frame-shear wall-thin walled member cooperating system with stepped parameters, in which flexure and torsion are coupled, have been derived. The analytical solution of these equations is complicated by its coupling and stepped parameters. Secondly, using the ODE (Ordinary Differential Equation) Solver, which is a program developed for solving various ODE, the fore ten vibration frequencies and vibration modes have been obtained. |
