In this paper, an attempt is made to 3D modeling and analysis of gravity dam of solid element using STAAD.Pro. The load and load combinations are taken as per IS 6512. Modelling of dam is considered in two categories, first is without openings and second is with openings. Result of stresses and stress contours are described at the end of paper. The paper is to have a direction of analysis of dam considering solid elements using STAAD.Pro.
