THE STUDY PROGRESS OF RECTANGULAR THIN PLATE BENDING PROPERTY UNDER THERMAL ENVIRONMENT WITH FOUR EDGES SUPPORTED

摘要

Concrete rectangular thin plate (CRTP) is not only broadly used to civil engineering but also broadly used to such fields as irrigation works and petrochemistry industry, mines, railway highway, and etc. In this paper, the analytical solution is obtained about the deflection and internal force of rectangular thin plate with different supporting (four simply supported edges, four clamped edges, three clamped edges and one simply supported edge, one clamped edge and three simply supported edges, two adjacent clamped edges and two simply supported edges, two opposite clamped edges and two simply supported edges) under temperature variations which are perpendicular to the surface. The result is proved reasonable by MATLAB software. So a theory calculation about CRTP with four sides supported under thermal environment in engineering structure is provided for engineering design.
