摘要
为研究大尺寸方钢管节点的受力性能,对10个平面十字形桁架节点进行了试验研究。结果表明:所有节点均表现为承压管上下两面下陷,两侧面鼓出破坏,其中承压管下加钢垫板后承载力有显著提高。各试件均满足设计承载力和变形要求。
The experimental research of ten specimens of crossing shape tress joints in plane was carded out to investigate the mechanic performances of square steel tube joints in large dimensions. Results indicates that the joints were all shown of deflections in up and down faces of main tubes, and expended in the two side faces. The bearing capacity of joint with steel plate under brunch tubes was improved greatly. All specimens had enough bearing capacity and deformed performances.
