| Abstract | Behaviors under static loading of the composite slab composed of corrugated steel and concrete topping are studied in this work using Nonlinear Finite Element Analysis. The main parameters are mechanical shear connector, concrete strength, thickness of corrugated steel and additional steel rebar placed on the bottom of concrete topping. The software ABACUS? is utilized in the analysis. The analytical results are compared and calibrated to the experimental results performed by previous researchers. The verified finite element model is used to study the effects of the principle parameters, which cannot be practically performed by the experiment. The results show that slab without shear connecter failed in the brittle manner due to interface slip of concrete and corrugated steel after flexural cracking of concrete topping. The horizontal shear connectors used to prevent the interface slip are significantly increasing the load carrying capacity of composite slab. This is because concrete topping and corrugated steel are perform composite action. However, the low thickness and cross sectional area of corrugated steel, lead to the low flexural and load carrying capacity of the composite slab. It can be said that corrugated steel acts as a form of concrete topping. The most effective method to increase the flexural capacity of composite slab is by adding reinforcing bar at the bottom of concrete topping and shear connectors. The additional reinforcing bar can delay the abrupt failure of the composite slab after flexural cracking of concrete topping. |
