[ 1 ] - تحلیل عددی رفتار دینامیکی سد بتنی وزنی تحت بار انفجاری داخل مخزن

بررسی­ها و تحقیقات در مورد رخداد انفجار در داخل مخزن سدها و تأثیر آن بر رفتار دینامیکی چنین سازه­هایی، با شروع جنگ جهانی دوم و پیدایش نیازهای اساسی برای تحقیق در این حوزه، ضرورت تحقیق در زمینه پدافند غیر عامل را گسترش داد. در مقاله حاضر پدیده انفجار داخل مخزن سد بتنی وزنی با استفاده از نرم­افزار اجزای محدود Abaqus بررسی گردید. در این بررسی دو مدل متفاوت از نظر هندسه و مشخصات مصالح برای سازه سد ...

[ 2 ] - Investigation of seismic damage index due to water level changes in reservoir through nonlinear dynamic analysis under Far-Fault and Near-Fault ground motions

In this study, reservoir water level effects on nonlinear dynamic response of concrete gravity dams are investigated. For this purpose, the nonlinear behavior of the dam concrete is captured using the concrete damage plasticity (CDP) on the non associated flow rule assumption. Water in the reservoir is represented by the Lagrangian (displacement-based) fluid finite elements. The program ABAQUS ...

[ 3 ] - Numerical Investigation of dip angle direction of foundation Joint on nonlinear dynamic response of concrete gravity dams

The stability of a gravity dam on a jointed rock foundation might be endangered by weak joints that may be present in the fracture network of the bed rock. A review of the literature shows that there are few studies of the effect of a weak joint in the foundation rock on the stability of dams. This research uses the finite difference numerical modelling software ABAQUS to model a gravity dam, t...

[ 4 ] - Investigate probability of damage of Earth dam under Near-field and Far –field earthquake : Case study Gotvand earth dam

The main goal of preset research is investigate the effects of vertical component of Near-Fault and Far-Field earthquake records on the probability of overtopping induced damage of earth dam due to the reduction of freeboard due to the settlement of dam crest. In this respect 12 different earthquake record are selected. Nonlinear dynamic analysis of earth dam is implemented with FLAC 3D using F...
