墙板模型高层结构空间分析程序BSSA的特点和应用

The character and application of the three-dimension analysis program BSSA for tall buildings with wall-slab element model

本文阐述了墙板单元模型高层结构程序BSSA的主要特点,并通过对典型考题和体型复杂的工程实例的计算分析,指出薄壁柱单元模型程序在一些工程计算中存在的局限性,对于重要工程必须采用不同力学模型的程序进行计算互校,确保工程安全可靠。

In this paper, the main character of program BSSA for tall buildings with wall-slab element model is expounded. By analysing the typical example and complex practical engineering, the authors point out that program with thin-walled column element model has limitation on the application in some engineering. In order to guarantee the security of important engineering, it is necessary to calculate with different mechanic models and the results must be compared with eath other.
