摘要
本文用沿高度方向连续化的方法,对平面内任意斜向布置的框架-剪力墙-薄壁杆协同工作体系,求得了其弯扭耦连振动时的自振频率和振型。通过解耦措施将动力方程分解,得出计算频率和振型的计算公式,用手算方法即可求解。
In this paper, by use of the continuum technique for floor slabs. thedifferential equations of horizontal vibration for tall building frameshearwall-thin walled member cooperating system, in which flexure and torsionare coupled, has been derived. A generalized-coordinate is used. Through thetransformation of coordinates, the differential equations are decoupled. Theformulas of calculating the vibration frequencies and vibration modes havebeen derived. The analysis work can be done with a small computer or even with acalculator.
