Analysis of the Lateral Load-bearing Behavior of Steel-concrete Composite Slabs
To clarify the transverse stress distribution in steel-concrete composite slabs,the differences in stiffness between steel beams and the damage conditions at the concrete connection points are con-sidered to propose a calculation method for determining the load transverse distribution coefficient of steel-concrete slabs.On this basis,a finite element model of the steel-concrete slab is developed,which is in good agreement with the actual bridge load test.The theoretical calculation results are compared and analyzed alongside those obtained from finite element analysis and the rigid connection plate method to research the effectiveness of the theory and the lateral stress mode of steel-concrete slabs.The findings indicate that due to concrete damage and stiffness differences,the lateral distribu-tion uniformity of steel-concrete slabs is weaker than that of the rigid connection plate method.The load-bearing capacity of the steel-concrete slab at the load application position exceeds the value calcu-lated by the rigid connection plate method,resulting in a limit load value from the rigid connection plate method being higher than the actual limit state.
