通过对5个不同试验变量(预应力水平、约束类型、焊接方法、剪力连接件)的试件进行试验来评估波纹钢腹板预应力梁的结构性能。试验结果显示,预应力组合梁的弯曲性能优于非预应力试件。对试件进行局部交互分析,研究钢梁和混凝土的水平剪力传递机制,详细讨论研究结果。
Structural properties of corrugated steel web prestressed beams were evaluated by testing specimens of five different test variables (level of prestress, type of constraint, welding method, shear connection). The test results show that the bending behavior of prestressed composite beams is better than non-prestressed specimens. The local interaction analysis of the specimens was carried out to study the horizontal shear force transfer mechanism between steel beams and concrete. The results of the study were discussed in detail.
