| 摘 要： | 通过8根部分剪力连接组合梁的静载和重复加载试验,在对试验过程、试验现象以及试验结果分析的基础上研究了重复加载对部分剪力连接组合梁受力性能的影响.试验结果表明,重复荷载作用下的部分剪力连接组合梁具有良好的抗疲劳性能;在焊接质量有保证的情况下,处于正常使用范围内的疲劳荷载作用下的部分剪力连接组合梁几乎不会发生疲劳破坏.因此必要的情况下在建筑结构和桥梁结构中采用部分剪力连接来承受疲劳荷载的作用是可行的,并可带来良好的经济效益.

| Abstract: | Through testing eight composite beams with partial shear connectors under dead load and repeated load,the effect that repeated load acts on composite beams is analyzed on the basis of the test process,phenomena,and result.The result proves that composite beams with partial shear connectors have better performance to support fatigue load in that they can hardly be destroyed under general fatigue load if the welding quality is reliable.So the application of partial shear connectors in the building and bridge structure to supporting the fatigue load is feasible,and will bring considerable economic benefits. |
