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 ...
متن کاملEvaluation of Nonlinear Response of Structures to Near-Fault Ground Motions and the Comparison of Results with Near-Fault Simulated Records
Near-fault ground motions have caused very much damage in the vicinity of seismic sources during recent earthquakes. It is well known that under specific circumstances, intensive ground shakings near fault ruptures may be characterized by short-duration impulsive motions. This pulse-type motion is generally particular to the forward direction, where the fault rupture propagates towards the site...
متن کاملCharacteristics of Horizontal and Vertical Near-Field Ground Motions and Investigation of Their Effects on the Dynamic Response of Bridges
Recently, concerning failure of structures due to earthquakes, special investigations of near fault ground motions have been noticed. Hence, in this paper, characteristics of near field ground motions have been considered in horizontal and vertical directions. In this consideration, the record averages have been compared with Uniform Building Code and Eurocode8 spectra in two levels. In additio...

متن کاملconsidering different criteria for minimizing torsional response of asymmetric structures under near-fault and far-fault excitations
an attempt has been made to explore the general trends in the seismic response of planasymmetric structures when subjected to near-fault and far-fault ground motions. systems with structural wall elements in both orthogonal directions considering actual and common nonlinear behavior under bi-directional excitation were studied. idealized single-storey models with uni-axial eccentricity were emp...
