Type: article
Abstract: Gravity dams are essential infrastructural elements used for water storage, flood control, and hydropower generation.Their structural safety and performance under varying loading and reservoir conditions are critical due to the potential risksassociated with failure. This paper presents a comprehensive review of structural analysis techniques for gravity dams, with aspecific focus on modeling through STAAD.Pro software. The study highlights the application of finite element methods (FEM)in simulating dam behavior under different forces, including hydrostatic pressure, uplift pressure, seismic effects, and selfweight. The role of STAAD.Pro as a versatile tool capable of handling complex geometries and material properties is explored indetail. Emphasis is placed on its ability to model solid elements and perform static and dynamic analyses in accordance with IS6512:1984 and IS 875 standards. The review synthesizes results from multiple case studies and simulations, examining factorssuch as stress distribution, displacement, sliding resistance, overturning moments, and shear friction parameters. Findingsindicate that STAAD.Pro provides accurate and reliable predictions for assessing dam safety under full and partial reservoirconditions. Furthermore, the study identifies common stress concentration zones—particularly at the heel—and discussesreinforcement strategies to mitigate structural vulnerability. It also evaluates the factor of safety under various loadingcombinations and confirms compliance with national safety codes. This paper contributes to the evolving methodology of damdesign and evaluation, offering valuable insights for engineers, researchers, and policymakers aiming to enhance the resilienceof gravity dams through advanced numerical modeling.
