摘要
本文在文献[2,1]所建立的平衡重体系运动方程的基础上,对高层建筑电梯系统中平衡重体系的动力特性进行了探讨,给出了求解该体系自振频率的近似方法,通过对一幢14层建筑内的平衡重体系进行的大量地震反应分析,研究了其动力反应沿建筑物高度变化的一般规律,给出了最大反应所处的位置。本文的工作为实施和推广文献[1]所提出的平衡重体系的抗震控制措施奠定了理论基础。
Based on the motion equation of balance-weight system (BWS) given in Refs. [2,1],the dynamic properties of BWS are studied in this paper,and an approximate method for determining its natural frequency is proposed. Then,the earthquake response analysis is made for the BWS in a 14-story tall building,and the places where maximum response occurs are pointed out. The work of this paper provides a foundation for carrying out the seismic control measure for BWS proposed in Ref. [1].
