THE ANALYTICAL SOLUTION ABOUT RECTANGULAR THIN SLAB WITH TWO OPPOSITE EDGES CLAMPED AND TWO OPPOSITE EDGES SIMPLY SUPPERTED UNDER TEMPERATURE LOAD

摘要

Rectangular thin plate is applied broadly in such many fields as construction, water resources, railway and so on. In this paper, based on the small deflection plate theory, and according to the deflection and internal force of rectangular thin plate of four simply supported edges under temperature variation which is perpendicular to surface, and through virtual work principle and overlapping principle, the analytical solution about deflection and internal force of rectangular thin plate with two opposite edges clamped and two opposite edges simply supported under temperature variation which is perpendicular to surface is derived for isotropic materials, and so a theory base is provided for subsequent engineering calculation.
