摘要
某超高层建筑为一高度为144.20米超限高层建筑,针对结构在地震作用下的扭转不易控制的特点,介绍了结构方案的决策过程,采用多个程序对整体参数进行了比较,无明显差异。对整体结构进行了弹性时程分析,计算结果表明均能满足规范要求。
A high-rise building with the height of 144.20m,which beyond the limit of Chinese Codes,is presented.The choosing of structure scheme is discussed aiming to the characteristics of irregular torsion response under seismic loads.Modes of different software are analyzed and compared and show same regulations of the controlling parameters.The results of the elastic time history analysis satisfy the requirements of the Codes.
