中国建筑科学研究院结构所研制的高层建筑结构三维分析程序TAT,采用了杆系有限元原理、引入梁元、柱元、杆元和薄壁柱元,对高层建筑进行三维空间分析。根据现行的规范对高层建筑的设计要求,进行了水平地震作用效应,竖向地震作用效应,风力和竖向力作用下的结构内力分析,地震作用效应可采用CQC组合并考虑了一、二级抗震等级时的设计内力的调整。最后对钢结构构件进行截面的宽厚比、高厚比、长细比以及整体 The TAT, a three-dimensional analysis program for high-rise building structures developed by the China Academy of Building Research, uses three-dimensional analysis of high-rise buildings using the finite element principle of bar systems, beam elements, column elements, rod elements, and thin-wall column elements. According to the current specifications, the design requirements for high-rise buildings are subjected to horizontal seismic effect, vertical seismic effect, structural internal force analysis under the effect of wind force and vertical force, and the effect of seismic action can be combined with CQC and considered one and two levels. The adjustment of design internal forces at the time of earthquake resistance. Finally, the aspect ratio, height-to-thickness ratio, slenderness ratio, and overall section of the steel structural member
