项目摘要

The state of art on the structural behaviors of beam-to-column connections was reported, and the experimental and analytical studies were carried out to propose the estimation formulae of strengths of connections.1.The estimation formulae of the local plastic and ultimate strengths of the connction between steel beam flange and concrete filled circular tube column are proposed based on the yield line theory.The out-of-plane moment and punching shear yield lines are assumed in steel tube, and the in-plane yield lines in through diaphragm are assumed.The cruciform model tests were carried out to investigate the structural behaviors with experimental variables of connection type, loading type, diameter-to-thickness ratio of steel tube and tube diameter-to-beam width ratio.The estimated local plastic and ultimate strengths agree with experimental results regardless of the experimental variables.2.Structural behaviors of the connections between concrete filled circular tube column and wide flange steel beam have been studied by the beam-and-column space subassemblage tests with experimental variables of connection type and yielding sequences of the consisting parts of space subassemblage specimen.The plastic and ultimate strengths of beam-to-column connections are analyzed by the yield line theory, giving good correspondence with the test results. And the plastic strengths of beam-end connection, column-end connection and connection panel are also discussed from the obtained strain measurements of the specimens.3.Structural behaviors of the connections between concrete filled square tube column and wide flange steel beam have been studied by the beam-and-column space subassemblage tests with experimental variables of connection type. The plastic and ultimate strengths of beam-to-column connection and beam-end connection are analyzed by the yield line theory, giving good correspondence with the test results.

本文报道了梁柱连接结构性能的研究现状，并进行了试验和分析研究，提出了梁柱连接强度的估计公式。基于屈服线理论，提出了钢梁翼缘与圆管混凝土柱连接的局部塑性强度和极限强度的估算公式。假设钢管的面外弯矩和冲切屈服线，假设贯通隔膜的面内屈服线。以连接方式、加载方式、钢管径厚比和管径梁宽比为试验变量，进行十字形模型试验，研究结构性能。无论试验变量如何，其局部塑性强度和极限强度与试验结果基本一致。以空间组合试件组成部件的连接方式和屈服顺序为试验变量，通过梁柱空间组合试验研究了圆管柱与宽法兰钢梁连接的结构性能。利用屈服线理论对梁柱连接的塑性强度和极限强度进行了分析，与试验结果吻合较好。并对梁端连接、柱端连接和连接面板的塑性强度进行了讨论。采用连接类型为试验变量的梁柱空间组合试验，研究了方筒混凝土柱与宽法兰钢梁连接的结构性能。采用屈服线理论对梁柱连接和梁端连接的塑性强度和极限强度进行了分析，与试验结果吻合较好。
