THEORETICAL CALCULATION AND ANALYSIS OF SLIP AND DEFORMATION FOR CONCRETE SANDWICH PANEL

This paper is concerned with the slip and deformation of concrete sandwich panel under uniformly distributed loads. The effect of slip on the deformation of concrete sandwich panel is studied，and the analytical expressions for slip and deformation of concrete sandwich panel is obtained. These formulae can describe the slip distribution and account for its effect on deformation. In order to restrict the bound of formula, the formula of crack moment is obtained. The results obtained by theoretical calculation are compared with experimental results and the results of finite element method. It is shown that the results obtained by theoretical calculation are in accord with that by experiments and finite element method. It can be used to calculate the slip and deformation of concrete sandwich panel in practical engineering.
