چکیده
The aim of this work is to take full advantage Spectral Element (SE) and Finite (FE) codes by setting up a SEM/FEM co-simulation strategy for soil structure interaction problems, involving SE code generate propagate elastic waves in the soil, while FE enables detailed representation studied structure. spatial coupling managed standard mortar approach, whereas time integration dealt with an hybrid (explicit/implicit) asynchronous (different steps) integrator. set linear or nonlinear transient dynamics. A seismic analysis concrete dam considered order demonstrate versatility assuming rheology damaging behaviour concrete.

متن کاملNonlinear Analysis of Concrete Gravity Dams by Neural Networks
Multi-layer neural networks have been used in this paper for modeling nonlinear behaviour of concrete gravity dams under earthquake excitation. Koyna dam which has been studied extensively by other authors in the past has been studied as test example in this paper too, where the nonlinear response of its crest has been modelled by the proposed algorithm. The main steps of the algorithm are as f...
متن کاملSimulating nonlinear behavior of CMD material in seismic analysis of concrete gravity dam
In recent years, a new type of dams namely CMD, has attracted so much attention. Different amounts of cement cause a type of behavior that be somewhere between those of embankment dams and conventional concrete dams. This behavior is not perfectly clarified and its analysis, especially under dynamical loading and in nonlinear region of the material, remains unclear. In this paper, Tobetsu dam h...

This study focuses on the shape optimization of concrete gravity dams considering dam–water–foundation interaction and nonlinear effects subject to earthquake. The concrete gravity dam is considered as a two–dimensional structure involving the geometry and material nonlinearity effects. For the description of the nonlinear behavior of concrete material under earthquake loads, the Drucker–Prager...
متن کاملSeismic and Stability Analysis of Gravity Dams Using Staad PRO
–This paper presents the main features and organization of STAADPRO, a computer program that has been developed for the static and seismic stability evaluations of concrete gravity dams. STAADPRO is based on the gravity method using rigid body equilibrium and beam theory to perform stress analyses, compute crack lengths, and safety factors. Seismic analyses could be done using either the pseudo...
