角钢格构式构架两种梁柱连接形式对比研究

文章针对角钢格构式构架常用的两种梁柱连接形式进行计算分析,在同等条件下对两方案的结构响应进行对比研究。计算结果表明:B方案(梁柱刚接)构架柱内力较小、构架梁内力较大、平面内位移较小、构架梁扭转角较小,综合比较B方案技术经济性较好。研究成果在工程设计中具有指导意义。

In this paper,two kinds of beam-column connections commonly used in angle steel lattice frames are calculated and analyzed,and the structural responses of the two schemes are compared under the same condition.The calculation results show that scheme B(beam-column rigid connection)has smaller internal force of frame column,larger internal force of frame beam,smaller in-plane displacement,and smaller torsion angle of frame beam.The research results have guiding significance in engineering design.
