Analysis Of The Two-way Superimposed Slab Simulation By The Finite Element Method

The traditional reinforced concrete two-way slab are widely used in civil andindustrial buildings, with the development of residential industrialization, new type ofthe superposed slab is increasing in the demand of practical engineering. And thenthe stress features of item and the difference between traditional two-way slab urgentlyneed to comparative analysis. To study on superposed two-way slab has upperreference value for future engineering design.This paper mainly describes the superposed slab with traditional two-way slabfrom the static load test. comparative analysis of the difference of deflection, strain ofsteel and development of crack, thus comprehensive evaluation of the traditionaltwo-way slab and two pieces of the superposed slab or three pieces of superposed slab.Based on the analysis of ABAQUS finite element nonlinear to simulate between thetraditional two-way slab and two pieces of the superposed slab or three pieces ofsuperposed slab, and point at the different thickness, different length-width ratio,inorder to show the difference of deflection, strain of steel and development of crack,findout and analyze the causes of error.The result indicates that the two pieces of superposed slab was at the same stressperformance in contrast to the traditional two-way slab. Finally we summarize theperformance of the two pieces of superposed slab in press state, then put forward somesuggestions and problems need to be solved, in order to provide a theoretical basis forimproving the superimposed shear wall structure, on the other hands, to providetechnical and theoretical supports for it can be widely used in high-rise buildings.
