# Synopsis Annular Slab Supported on Columns Along Inner Boundary and Fixed at Outer Boundary

*The objective of this study is to analyse an annular slab fixed at the outer edge and supported by equally spaced columns on the inner edge. The thin plate theory is used
in this analysis. The results are presented in the forms of a table and charts which show that deflexion and stress resultants decrease as the ratio of the inner radius to
the outer radius increases. The number of columns, with the range of four to sixteen, has not much effect on maximum radial bending moment, but the maximum magnitudes of the other stress resultants and deflexion decrease as the column number increases. Reducing the column width increases the shearing forces and the transverse bending moment. However, the deflexion and the radial bending moment are insensitive to the variation of the column width.*
