摘要
本文首先利用有限条法分析高层建筑筒体结构的静力方程,采用静力缩聚法,求出结构的侧向刚度矩阵,然后将结构质量等效集中到各层楼面,最后导出了结构平动一扭转耦联振动基本方程.由此可以按反应谱理论计算地震荷载.
In this paper, the static equations of the tube structure in superhigh buildings is analyzed by finite strip method. The lateral rigid matrix is obtained by means of the static reduction technique first. Then the mass of structure is concentrated equivalently on each of floors and the basic equatjons of coupled translation-torsion vibration of fhe structure are derived. Hence the earthquake loads can be calculated according to the response spectrum theory.
