ANALYSIS OF DESIGN PARAMETERS OF STEEL JOINTS WITH FORCE-TRANSFERRING PLATES FOR STEEL COLUMNS WITH IMPERFECT

摘要: 利用大型通用软件ANSYS,对不考虑缺陷的外传力钢框架节点试件进行分析,并与1/2缩尺试验结果进行对比,证明了模型的正确性。另外在钢柱垂直度偏差为设计标准所允许值5倍的条件下,建立6组不同钢梁翼缘宽度、厚度的试件,并相应调整传力板的设计参数,通过分析荷载-位移曲线以及应力分布情况,得出所加设的传力板厚度应与钢梁翼缘厚度相同,宽度宜为钢梁翼缘宽度的0.75~1.25倍。

Abstract: ANSYS software was used to analyze steel joint specimens with force-transferring plates without considering the imperfects，whose results were compared with the results of 1 /2 scale test，which verified the correctness of the models． When the vertical deviation was five times as many as the permission of the code，six groups of specimens with different width and thickness of steel beam flanges were designed and the key parameters of the adding plates were adjusted． The analysis of load-displacement curves and stress distribution showed that the thickness of adding plate should be the same as that of the steel beam flange and the width of the plales should be 0. 75 ～ 1. 25 times as that of steel beam flanges．
