高层建筑地震作用时程分析法计算要点

Key Points of Time History Analysis Method for Calculation of Seismic Action of High-rise Buildings

根据规范规定给出时程法定义、分类、波形选择方法、调整系数计算公式;明确选波时用底部剪力值,计算调整系数时用各层间剪力值;总结了时程法与反应谱法之间的区别与联系,并以具体工程为例说明时程法作为反应谱法的一种补充计算以及对内力调整的过程。

According to the code,this paper gives the definition,classification,wave form selection method and adjustment coefficient calculation formula of time history method;defines the bottom shear value when selecting wave,and the shear value between layers when calculating the adjustment coefficient;summarizes the difference and connection between time history method and response spectrum method,and explains the time history method as a supplementary calculation of response spectrum method for internal force with a specific project as an example and the process of adjustment.
