Abstract

Concrete gravity dams are important lifeline structures and represent the fragrance of people’s standard of living. These are very complex structures and subjected to various types of forces both static and dynamic in nature. Optimization techniques plays an effective role in structural design in which the structure can be designed in such a way that the area and volume can be optimized and hence the requirement of the materials can be effectively reduced and thus it minimises the cost of construction. In the present study, 3 different geometrical shape (cross section) of non-overflow section is considered and a two dimensional (2D) Finite Element models are created. All major load/forces are calculated and applied as primary load cases and load combinations are generated for the most adverse load combination A, B and C as per I.S 6512-1984, using Finite Element software STAAD pro V8i. The stress contour pattern and behaviour under various load combinations are evaluated and stress distribution is visualised. The maximum displacement of the dam crest is observed for the various load combinations. A comparative study is made between conventional and STAAD pro analysis for maximum principal stress and shear stresses at heel /toe/ in dam body for the various load combinations as per I.S. Codal guide lines for dam with fixed base.
