Nonlinear Analysis Of New Type Composite Wall And Plate

With the continuous development of our economy and our country residents’ demand for housing, prefabricated structures get rapid promotion and application in our country. Compared with the cast-in-place slab which we know it, there are a lot of advantages, such as production factory, manageable size and form, construction is convenient, reduce the use amount of template, short time limit for a project, cost low etc.Using ANSYS software for the same size and reinforcement ratio of the reinforced concrete site casting and applying the same double composite plate series load, simulated and analyzed on the basis of the finite element software, research the composite floor slab under different static function and parameter Settings in the stress strain and deflection deformation at each stage. Than the result of the simulating value with material properties, dimension and reinforcement ratio of the same test results be compared. To show the differences between them.To simulated analysis "一" of the same size font cast-in-place shear wall, composite shear wall with dark column, the superposition type with side column shear wall, study the structure under the action of axial compression ratio for the side load the load- displacement deformation relationship of each stage. Compare the cast-in-place shear wall with embedded column composite shear wall and with a side column composite shear wall failure pattern and the difference between carrying capacity. To compared the simulation results of the three types of wall with the same as the size and reinforcement ratio of the existing test data, the result of the simulation and experimental results show the differences. Studied at the top of the wall under the condition of axial compression ratio of 0.1, the wall side under different levels of load than to change the diameter of the steel the change of the stress, how much the diameter of the steel bar will be able to guarantee transfer shear.Research shows that: the cast-in-place floor slab and double composite floor slab in elastic stage deflection are basically identical; After the plastic stage, with the increase of load, due to the double composite plate when the load increases after the plastic stage flat-fell seam in bending stiffness drastically reduce the deformation of a site casting leads to a double composite panels have obvious increasing trend. Based on reinforced concrete site casting and double composite plate simulation value compared with the test results shows that simulation results than the results coincident with strike, but the results are smaller than test results, the reason from the simulation is an ideal state of articulated, not considering the reality of four edges supported beam deflection and torsion factor’s influence on the displacement of plate.Cast-in-place shear wall and two kinds of new type composite shear wall load-displacement curve line. Cast-in-place shear wall and superimposed type shear wall under horizontal load is one of the largest plastic deformation mainly concentrated near the connected with the base of the cross section, and the plastic range is small. Cast-in-place shear wall deformation of the final from two kinds of new type composite shear walls of the final deformation. With dark column composite shear wall and the damage form of superposition type with the column shear wall and there was no obviously difference between the carrying capacity, in comparison, set the dark column than setting the column is more cost-effective. The same axial compression ratio of three kinds of shear wall simulation characteristic value simulation results are compared with the test results that the test results is big. The research results of new type composite floor and new composite shear wall have great significance to the design and use.
