Finite Element Analysis on Contact Surface Slip of Profiled Steel Sheet and Composite Slab

Abstract:

In order to evaluate correctly the load-bearing performance of the prestressed profiled steel sheet composite slab，according to actual loading conditions, finite element model of the prestressed profiled steel sheet and concrete composite slab is established. Numerical simulation is made to the slip of the prestressed composite slab. The calculation results show that the slip of the prestressed composite slab at ultimate status will be gradually reduced with the improvement of the concrete strength. When increasing the prestress, the slip value at ultimate status will be less reduced and increasing the thickness of the concrete can reduce the slip value at ultimate status, the deformation of the prestressed composite slab will be increased by over 10% when considering the slip of the bonding surface.
