| 摘 要： | 以16 m跨径的T梁桥标准图为基础,按1:4的缩尺比例,采用焊接钢板的连接方法设计了一座5片T梁桥模型.人为制造横向连接损伤,研究了带横向连接损伤的T梁桥模型极限承载力.试验结果表明:在横向连接损伤的情况下,其两侧梁各自暂时形成一个子系统.在跨中加载的情况下,各子系统绕着损伤横向连接发生约束扭转.并且这种约束扭转状况随着横向连接损伤程度的增加而越发明显.横向连接损伤对桥梁的破坏形式产生了极大的改变,对桥梁的极限承载力影响很大.

| Abstract: | The effect of damaged transverse connection to prefabricated concrete T-beam bridges was studied through model experiment and finite element analysis in this paper.On the basis of standard drawing of 16 m T-beam bridge,one 4 m prefabricated concrete model T-beam bridge by using of welding steel plate was designed.The transverse connection was then damaged artificially and the ultimate bearing capacity of this bridge model was investigated.Experiment results indicate that: When the transverse connection was ... |
