Abstract Finite element analysis was conducted on the stress, vertical displacement, and horizontal displacement of ordinary concrete ductile gravity dams under different working conditions. The results show that: with decrease height dam, stresses two gradually increase, displacements a decreasing trend during operation period. Under effect earthquakes, maximum stress kinds appears at weak point dam body. normal water level falling reach 9.91 MPa 9.85 respectively. types seismic conditions is approximately 4 times that conditions, are always smaller than concrete.

In this work, meta models considering the non-linearity of problem are dedicated to determining displacements crest and foundation Koyna dam model. ABAQUS 6.14 program is used create numerical simulations by employing extended finite element method XFEM with presence earthquake time history data for 10 seconds. Five factors related foundation's material properties reservoir depth involved in an optimization study. The Pareto adopted support MATLAB codes calculate optimized values participating factors. A multi-objective function authorized two being predict minimum during seismic action addition crack damage propagation. results declared that 100% efficient estimating response structural system dam. five were determined. displacement was 1.372 m 0.319 m, which approved optimality compared model outputs generated models. Consequently, dam's stability control accomplished high reliability verifying benchmark.

In this paper, we focused on the advancement of Dam Monitoring Software that incorporates Finite Element Method (FEM), as these large infrastructure constructions are crucial for ensuring a dependable water supply, irrigation, flood control, renewable electric energy generation, and safe operation, which is utmost importance to any country. However, material properties geotechnical environments dams can change (deteriorate) over time, while standards legal norms govern them become more rigorous, so in order accurately assess state dam detect concerning behavior, software must be updated well. The custom-developed FEM solver, unlike many commercial alternatives, adaptable reconfigured function within System. present procedure interpolating numerical values at measurement points, when position point does not align with node element, allowing additional instrument locations added monitored system without need remeshing model. This used compare actual pore pressures temperature concrete structure prediction model, agreement much greater new interpolation algorithm comparison nearest nodal values, average relative difference pressure reduced from 8.89% 8.10%, justifying implementation.
