Near-fault seismic damage patterns and failure scenarios prediction of concrete gravity dams using nonlinear incremental dynamic analysis
Performance based earthquake engineering approach has been under evolution for seismic safety assessment of structures. Qualitative and quantitative definition of seismic performance levels is major challenge of concrete gravity dams. The main purpose of this article is damage patterns and failure scenarios prediction of structure while they prepare a suitable basement to determine dam seismic ...
متن کاملA STUDY ON NONLINEAR BEHAVIOR AND SEISMIC DAMAGE ASSESSMENT OF CONCRETE ARCH DAM-RESERVOIR-FOUNDATION SYSTEM USING ENDURANCE TIME ANALYSIS
In the present paper, nonlinear behavior of mass concrete simulated by smeared crack model is combined with Endurance Time Analysis (ETA) method for studying seismic response of arch dams. ETA is a time-history based dynamic pushover procedure in which special predesigned intensifying acceleration functions are used for analysis and estimation of structural responses in various performance leve...
متن کاملAre There Any Differences in Seismic Performance Evaluation Criteria for Concrete Arch Dams?
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...
متن کاملSeismic and Stability Analysis of Gravity Dams Using Staad PRO
–This paper presents the main features and organization of STAADPRO, a computer program that has been developed for the static and seismic stability evaluations of concrete gravity dams. STAADPRO is based on the gravity method using rigid body equilibrium and beam theory to perform stress analyses, compute crack lengths, and safety factors. Seismic analyses could be done using either the pseudo...
متن کاملMULTI-OBJECTIVE OPTIMIZATION OF ARCH DAMS USING DIFFERENTIAL EVOLUTION METHODS
For optimization of real-world arch dams, it is unavoidable to consider two or more conflicting objectives. This paper employs two multi-objective differential evolution algorithms (MoDE) in combination of a parallel working MATLAB-APDL code to obtain a set of Pareto solutions for optimal shape of arch dams. Full dam-reservoir interaction subjected to seismic loading is considered. A benchmark ...
