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。
In this paper, the method of segmental continuous along the height direction is adopted. For the frame-shear wall-thin-walled tube working system that is a stepwise deformation section along the height direction and is arranged in an arbitrary oblique direction in the plane, the bending-torsion coupling is established. The vibration equation is solved by the ordinary differential equation solver (COLSYS) for the natural frequency and the corresponding mode shape.
