| 摘 要： | 为研究边柱埋入式钢柱脚节点U型钢筋的设置对节点受力性能的影响,掌握节点的破坏机理,进行了ABAQUS单调加载非线性有限元分析,根据分析结果,得到柱脚节点的应力变化过程、弯矩-转角曲线等。并得到边柱埋入式钢柱脚节点的破坏机理,建议现行规范JGJ 99—98《高层建筑钢结构设计规程》对边柱埋入式柱脚增加设置U型钢筋的相关条文。

| Abstract: | In order to study the behavior and the damage mechanism of embedded column base joint with U-type reinforcement parameters,an finite element analysis has been carried out under monotonic loading.Based on the analysis results,the stress change process,moment-rotation curve,and other aspects were obtained.The failure mechanism of embedded steel column base joint was also analyzed.Based on the findings,is was suggested that relevant provisions of u-rebar should be added to the present code "Code for Design of High-Rise Building Steel Structure"(JGJ 99-98) were suggested. |
