Experimental Study On Reinforced Concrete Superimposed Slabs With Connections And Nonlinear Numerical Simulation Based On ANSYS

At the present time,residential construction is in stage of persistent unprecedented development,and is becoming the new economic growth point,With the improvement of the level of architectural science and technology and the modern development of the residential industry higher requirement on building materials and environmental protection was brought forward.Various new materials and new structures emerged as the times require.As far as floor slabs,for the sake of facility of construction and quickening construction progress,multiform superimposed floor slabs have been appeared,such as cold-formed steel-deck concrete floor slabs,and long-span coreboard etc.This paper explored the reinforced concrete superimposed floor slabs produced by Germany.Based on the static loading experiment of four reinforced concrete floor slabs, two ordinary and two superimposed with connections, the paper studied their loading mechanism and bending performance, such as deformation, cracks, bearing limit and fail characteristics. Besides,With the FEA program, ANSYS,adopted, the numerical annlysis for each slabs under the monotonous static load is simulated,and the corresponding results are compared with the experimental ones. Finally, proposals for superimposed slabs' design were put forward.
