某超高层建筑斜撑—柱转换结构节点力学性能分析

Mechanical property study on the bracing-strut transforming joints of a super high-rise building

为了研究斜撑—柱转换结构节点在最不利内力下的应力分布和变形情况,利用有限元软件ABAQUS对其进行了数值建模和分析,结果表明,在最不利内力下,该类型上下节点均满足承载力要求;在中震作用下节点处于弹性状态,节点的力学性能能够达到设计目标。

In order to study the stress distribution and deformation of bracing-strut transforming joints under the max inner force, the finite ele-ment software AB AQUS is used to analyze the upper and lower joints of the batter post, the results show that these type of joints meet the require-ments of carrying capacity under the max inner force, and the deformation of it still be in elastic stage under the middle earthquake. The me-chanical property and the performance of these joints are well.
