Structural Analysis of Three-Cell Box Culverts: A Study Considering Different S/H Ratios with Diverse Skew Angles

Abstract

Abstract: A crucial role is played by box culverts as vital structures, having been constructed in diverse forms and dimensions to meet a range of waterway and traffic requirements. A pathway beneath roads is offered, ensuring safe traversal without road traffic disruption, thus providing users with a secure journey. Typically, box culverts are utilized for this purpose. A variety of pressures from water, traffic, cushion, and soil are endured by these structures. In this paper to check the box culvert against various loads and alignment, 3 box cell culvert with 12 distinct cases have taken A2 to L2 having 4 sets of models of different S/H ratios 1.5, 1.75 and 2. In each sets, 4 combinations have taken of different skew angles viz. 0, 17, 34 and 51 degree respectively. After then these all 12 models have checked and efficient model under head of each degree and S/H noted. Finally, the result concluded that use skewness up to 17 degree with more S/H ratio to create an economic 3 cell box culvert.
