摘　　要：对水平作用下箱型钢柱和H型钢梁节点柱内加劲板的设置进行了分析研究。运用有限元软件进行计算,提出以名义刚度作为节点抗侧力性能的评价指标,准确可靠,有效地避免了有限元计算时收敛判断不准确造成的计算终点的偏差。对不同梁高时不同加劲方式下的节点性能的比较研究表明,梁柱节点的加劲效果受梁高的影响,梁高越高,加劲效果越好。其中,同时设置竖向和横向加劲板时,在各种梁高下都表现出很好的性能,推荐使用。此研究结果可为同类工程提供参考。In this paper, the design for diaphragm in connections between box-shape columns and H-shape beams subjected to horizontal load is analysis. With the study using finite element analysis, nominal stiffness as a evaluation of horizontal resistance behavior of the connections is given,it is accurate and reliable and did not influence by the error of calculation endpoint that caused by uncertainty convergence criteria in finite dement analysis. The study of different kind of diaphragm in different height of beam showed ,the effect of diaphragm was affect by the height of beam, as the height becomes larger, the effect of diaphragm becomes better. When the diaphragm was set both in vertical and horizontal way, the connection shows good behavior in any height of beam, so this kind of diaphragm is recommended. This study provide a reference for similar projects.
