Experimental and Nonlinear Analysis of Cracking in Concrete Arch Dams Due to Seismic Uplift Pressure Variations

Cracked concrete arch dam’s behavior due to moderate earthquake magnitude and water pressure variation was investigated. Plain used cast the models with 45 Mpa design strength. A shake table has been planned, manufactured, built create a dynamic testing facility. The experimental work included of four scaled-down dams’ models, which is divided into two groups, each group contains different degrees curvature models. An artificial crack made at center body. extended finite element method (XFEM) outlined in order address numerical predicate for propagation crack. results showed that good all dams under intensity. dam higher degree recorded 17.8% 16.2% low displacement Z X-direction respectively, stress evaluation comparison owns lowest curvature. Hence, increasing led raising stability dam, resistance, less displacement, growth tensile cracks.
