Abstract: In the present paper, seismic performance of a high concrete arch dam is evaluated based on both the stress and strain criteria. For this purpose, the finite element model of the selected arch dam-reservoir-foundation system was provided. Reservoir was modeled using Eulerian approach as a compressible domain and the foundation rock was assumed to b... Show More

Abstract: Recent earthquakes have damaged many lifeline structures. Buried gas pipelines are also no exceptions. Sometimes, theses pipes are subjected to a thinning of the wall thickness due to corrosion. Therefore, it is important to evaluate the strength of the pipes undergoing local wall thinning to maintain the integrity of the piping systems. The main p... Show More
