| Abstract | A rational analysis of a rectangular plate with eccentric stiffeners is carried out by a variational principle, leading to a governing differen— tail equation of order ten involving one parameter, which characterizes the stiffness of the intersection of the stiffeners. This parameter is determined in such a way that the solution of the anticlastic bending obtained from this proposed theory agrees well with the experimental results available. Neglecting the lateral bending and the big moments of the ribs yields an approximate theory with an eighth order differential equation. To make this study more practical, a fourth order governing equation is derived from the eighth order theory in such a way that the pure tor— signal rigidities are kept identical to those by the higher order theories. The results by these two approximate theories, for the case of a plate under a cylindrical bending and a simply supported plate subjected to a uniform load, agree closely with the reSults by the original ten order theory. By the fourth order governing equation, an approximate analysis for the design of a reinforced concrete waffle slab supported by rows of columns is investigated. The maximum deflection, moments and shear forces for the design are obtained for the corner, exterior and interior panels. |
