Nonlinear Finite Element Analysis Of Reinforced Concrete Superimposed Floor Slabs Based On ANSYS And Experiment Research

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 two blocks of usual reinforced concrete superimposed floor slabs, obtained the performance of the slabs, such as load-strain relation, load-deflection relation, cracking load and limiting load, so as to study the bending capability and the process of bearing the load and the failed characteristics of the floor slabs under the monotonously static loading experiment .Besides, by using general purpose finite element program-ANSYS, this article made nonlinear finite element analysis and practical mechanic analysis models of reinforced concrete superimposed floor slabs, superimposed floor slabs with joints and superimposed floor slabs with reinforced joints. By comparison of analysis results and experimental results, offering many useful conclusions, offering an effective reference for later computer simulative experiment of this structure.
