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 the static load and repeated loading tests of eight partially shear connection composite beams, the effect of repeated loading on the stress performance of partial shear connection composite beams was studied on the basis of the analysis of the test process, test phenomenon and test results. The test results show that the partial shear connection composite beam under repeated load has good fatigue resistance. Under the condition that the welding quality is guaranteed, the fatigue failure of part of the shear connection composite beam under the fatigue load within the normal use range will hardly occur. Therefore, it is feasible to use partial shear connections in building structures and bridge structures to bear fatigue loads when necessary, and can bring good economic benefits.
