Abstract:
An attemA is made here to present the bowl distribution analysis based Oa the Anisetropio Plate Theory as applied to modern grid beam bridge*, with special reference to edge stiffened and contin. uous bridges.
As a basis for the subsequent work the *basic analytto theory as applied to simply supported grid beam bridges has been briefly indicated. Analytical approach as extended to edge stiffened and continuous bridges has boon presented. Approximate methods for ocatinaous bridges based on Equivalent Stiffness and misused defleoted shapes have been developed. At all places the result, have been compared with these obtained by other standard load distribution theoriess
The analytical results have also been supp. lamented by suitable model tests*
The model test results have been found to
agree fairly well with the approximate solutions presented for the edge stiffened and continuous bridges. It is felt that these approximate solutionscan be safely used for design purposes, while at the same time making the analysis within easy reachof the Design Engineer's
