| Abstract | ||||
| In this paper, a nonlinear finite element model (FEM) was developed using ABAQUS 6.14 to study the effect of the upper steel mesh on the behaviour of mono-symmetric steel-concrete composite (SCC) beams provided with channel shear connectors. Moreover, the FEM will be used to calculate the effective width of the concrete slab against the existence of upper steel reinforcement mesh and compare the results with the calculation of the effective width in the universal codes (i.e., AISC 360-15, CSA S16-14 and the Eurocode 4; CEN 2004). In this respect, six (SCC) beams were modeled to study the effect of the upper steel mesh on SCC beams' behaviour. The results of this study showed that the increase in the ratio of the upper steel reinforcement mesh is affecting the value of the ultimate load, mid-span deflection value and slip value at the steel-concrete interface. The presence of upper steel reinforcement mesh with a ratio of 0.91% from the area of the concrete slab leads to decreased vertical deflection by 32.5 % at the ultimate load of the beam without upper steel reinforcement mesh for beams. Also, the slip value decreased by 60 % at the ultimate load. Also, the effective width of the concrete slab for beams provided with the channel shear connectors increases with the increase in the ratio of the upper steel reinforcement mesh. | ||||
