【摘要】 以连杆节间为界，按弹性支座上的Ｔｉｍｏｓｈｅｎｋｏ悬臂梁建立剪力墙部分的振动方程，按一般框架建立框架部分的振动方程．根据力、位移协调条件，形成底层大空间高层建筑结构的自由振动方程，并据此计算其自由振动．更多还原

【Abstract】 Tall Building Structure with large open space at ground floor level is divided into frame substructure and shear wall substructure by cutting the connectingbeams. The vibration equation for shear wall substructure is set up according to Timo-shenko cantilever beam with spring supports at the bottom. The vibration equation forframe substructure is set up according to frame structure. The free vibration equation ofthe structure is set up by using force and displacement coordination condition.更多还原
