Methods used in analysis and design time durability of concrete dams Weighted Lrz·hyy

Methods used in this article last time Lrz·hyy linear analysis of concrete dams has been investigated by weight. This relatively new technique, based on time history analysis is expected with the development of its application in analysis of concrete dams can be useful information in relation to the performance and margins Lrz·hyy against criteria designed to ensure achieved. Comparison of two dams and Fvlsvm Kvyna area under the line of earthquakes shows that the method last time, has the ability to predict the behavior of dams under earthquakes when they are equivalent to each earthquake occurs. Also to assess the overall dam levels linear mode can be time OBE in the base level corresponding to the time zone OBE considered. If the last time the failure index based Dam Tyynshdh OBE in balance over this time base, the dam and if desired resistance is less than this time, the dam is weak for the balance of OBE. Total duration time method will facilitate the assessment done
