Modeling and Load Analysis Slab Bridge on Diu Lake Bridge

Abstract

The increasing pace of urbanization and infrastructure growth is making complex transportation systems increasingly required. This condition along with additional constraints for aligning the bridges correctly are what allow an increasing number of slab bridges to be built. Slab bridges are commonly employed in rural planning when geometry makes it impossible to build the appropriate bridges. In this paper, the behavioral properties of slab bridges are analyzed and compared with straight bridges using CSI-Bridge Analysis software. At critical places where the slab bridge has an influence, the maximum bending moment, maximum shear force, maximum torsional moment, maximum deflection from dead load, and maximum deflection from live load are all shown. IRC Class Hsn-44 live load Tracked Vehicle and Moving load VECL1 Load case define vehicle class HL-93S, HL-93K, HL-93M, all load case use AASHTO code 2014.The highest tensile forces and sheer are found at the ends and lower portion of slab bridges, where reinforcing steel rods are twisted or roughened. Slab bridges are made up of a single, flat concrete beam known as a slab. The amount of steel and depth are chosen based on the length and live-load capacity of the slab. Powerful Simply supported bridges are made up of horizontal beams connected across a single span, and continuous slab bridges are made up of beams connected over two or more spans. Substructure modules provide support for slab bridges at both ends.
