Abstract: Basements are generally used as a utility space for a building where mainly parking is located. However, all the works are to be done in the congested underground environment inside the basement pit in confined space. In such places, precast concrete panels can be used. To make the application of precast concrete pavement economical and material effective, an attempt has been made to provide a curved bottom face. Curved panels are easy to place, consume less material, and are cost efficient making them more economical. They provide better consolidation of soil due to the curvature provided at the bottom face as compared to a regular (flat based) concrete panel. In order to optimize the curve, that needs to be provided at the bottom face, finite element analysis has been performed. The curved panels are optimised, based on the maximum shear force and bending moment obtained through analysis. Comparison of the key design parameters is made between the curved and regular panel. It is observed that values of optimised curved panels are less to regular panels.
