Bond Slip Effect of Composite Trough Beam with Corrugated Steel Web Wrapped with Steel Plate and its Influence on Displacement Under Different Loading Conditions
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.
