The Bending Problem Study Of The Plate With Concave Corner In The Transformation Of Old Building

The special shaped plate becomes more and more widely used in transform of old town withinthe reform and development of the construction industry. However, the analysis of the special-shapedplate in the calculation of engineering design and analytical elastic solution is very deficient. Thispaper mainly studies the analytical solution of the special-shaped plate and finite element numericalsimulation.This paper mainly studies the elastic analytical solution of the special-shaped plate which issimply supported at four edges and suffered uniformly distributed load. Proposed to let thespecial-shaped plate divide into five rules of rectangular plates, and on the basis of the basic theory ofrectangular plates, using the boundary conditions and continuity conditions to get a simultaneoussolution of the five regular plates. In the application of continuous conditions, three kinds ofassumptions is maked, the assumption of continuity conditions based on constant; the assumption ofcontinuity conditions based on the cosine function; the assumption of continuity conditions based onparabolic function. According to three assumptions, the solution of the special-shaped plate deflectionequation is obtained, and get the maximum deflection of the special-shaped plate.Secondly, establish the finite element models of special-shaped plate by ANSYS, and make acalculation for different materials, different size of special-shaped plate. Get the maximum deflectionin the finite element solution of special-shaped plate. Make a comparison of the theoretical solutionand the finite element solution, and shows the theoretical solution’s reliability and applicability.But, in construction engineering, the special-shaped plate is mostly reinforced concrete plate,considering the combination with the engineering practicability, in this paper, using the ANSYSsoftware to make a simulation calculation for reinforced concrete special-shaped plate in differentmaterials, different size. Comparison shows that the reinforced concrete special-shaped plate lengthand missing Angle size having an effect on the maximum deflection and maximum stress. It canprovide a new reference for the calculation of the special-shaped plate in construction engineering.
