Due to the construction technology of roller compacted concrete (RCC) gravity dams, there are many weak layers that have potential affect seismic performance dams. However, research on response and failure characteristics RCC dams considering their layered characteristic is still lacking. In this paper, zero-thickness cohesive element presented model mechanical behavior layers. An impacted beam...

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...

Dynamic dam-foundation interaction is great important in the design and safety assessment of dam structures. Two classic boundary conditions, i.e., viscous-spring viscous boundary, are employed to consider radiation damping unbounded rock foundation. The input models seismic excitation derived. accuracy two conditions dynamic analysis foundation verified through using an impulsive load. influen...

it is correct control and monitoring of modern embankment dams that are very vital in the geotechniqual constructions. the improvement of methods of stability control, using the effective stress and the measurement of ganglionic water pressure in embankment dams cause more the safety for this kind of dams. nowedays there is such an idea that in stead of using of being safety factor against coas...
