Abstract

Composite trough beam with corrugated steel web wrapped with steel plate (CTBCS) is a trough beam composed of several components, which has a good application prospect in rail transit system. As CTBCS is composed of several components, the bond slip between the interfaces of the components can cause additional displacement. In order to study the bond slip effect of CTBCS, the calculation formulas of additional displacement caused by bond slip effect were first derived theoretically, and the accuracy of the formulas were verified by comparing theoretical results with simulated results. Then, the proportions of different kinds of displacements to the total displacements were studied, among which the bending displacement accounts for the largest proportion of the total displacement, about 55%-70%, the shear displacement and the bond slip displacement account for about 30% and 2%-10% respectively. Finally, the influence of beam parameters on bond slip displacement was analyzed, the study results show that the influence of different beam parameters on the bond slip effect varies, and the influence of the thickness of steel plate is negligible. The analysis results of this paper can provide data support for the selection of beam parameters in the design process of CTBCS.

钢板包裹波纹钢腹板的复合槽形梁的粘结滑移效应及其在不同荷载条件下对位移的影响

钢板包波纹钢腹板复合槽型梁（CTBCS）是一种由多个构件组成的槽型梁，在轨道交通系统中具有良好的应用前景。由于 CTBCS 由多个构件组成，构件界面之间的粘结滑移会引起附加位移。为了研究 CTBCS 的粘结滑移效应，首先从理论上推导了粘结滑移效应引起的附加位移的计算公式，并通过理论结果与模拟结果的对比验证了计算公式的准确性。然后，研究了各种位移占总位移的比例，其中弯曲位移占总位移的比例最大，约为 55%-70%，剪切位移和粘结滑移位移分别约占 30%和 2%-10%。最后，分析了梁参数对粘结滑移位移的影响，研究结果表明，不同梁参数对粘结滑移效应的影响各不相同，钢板厚度的影响可以忽略不计。本文的分析结果可为 CTBCS 设计过程中梁参数的选择提供数据支持。
