Differences between stress-based and strain-based criteria are investigated in seismic performance evaluation of the arch dams in time domain. A numerical model of the coupled dam-reservoir-foundation system is prepared with the finite element technique. Reservoir is modeled using the Eulerian approach as a compressible domain, and the foundation rock is assumed to be massless. Dynamic equilibr...

For the structural health diagnostic of concrete dams, mathematical monitoring model based on measured deformation values is great significance. The main purpose this paper to reconstruct ageing component and temperature in traditional Hydraulic-Seasonal-Time (HST) hybrid by combining values. On one hand, a better for displacement dams proposed combined with Burgers separate instantaneous elast...

the nonlinear discrete crack modeling of Shahid Rajaee thin arch dam is considered. The interface elements are positioned such that certain potential separated blocks can form possible failure mechanisms. The dynamic stability of theses blocks are investigated by a special finite element program "MAP-73" which its nonlinear algorithm and interface elements formulation are presented.
