Elastic And Plastic Finite Element Ultimate Analysis Of Reinforced Concrete Thin Slabs

On the basis of the traditional elasticity theory, ultimate theory and theory of reinforced concrete slabs with simple-supported condition, this paper analyzes the whole process of reinforced concrete thin slabs in the loading test of distributing static load, on the objects of reinforced concrete thin slabs with complex geometry, complex boundary condition and distributing of reinforce bars. And then analyzes the load capacity under the effecting of static load.And then, according to finite element theory of reinforced concrete, the main calculating program of "Elastic and Plastic Finite Element Ultimate Analysis of Reinforced Concrete Thin Slabs" is made by using the rectangle element with 4 crunodes and 12 freedoms of elastic thin slabs, calculate the stiff matrix and the matrix of internal force by considering concrete as anisotropic material under effecting by two-way stress. Then this paper investigates the finite element program by using Fortran language.Finally, according to the research, some feasible advice is put forward for engineering design.
