Simulating nonlinear behavior of CMD material in seismic analysis of concrete gravity dam
In recent years, a new type of dams namely CMD, has attracted so much attention. Different amounts of cement cause a type of behavior that be somewhere between those of embankment dams and conventional concrete dams. This behavior is not perfectly clarified and its analysis, especially under dynamical loading and in nonlinear region of the material, remains unclear. In this paper, Tobetsu dam h...
متن کاملThe effect of earthquake frequency content and soil structure interaction on the seismic behavior of concrete gravity dam-foundation-reservoir system
The effect of frequency content on the dynamic response of concrete gravity dams is investigated in this paper. Dams are one of the most complex structures to handle when there is dynamic analysis involved. One of the influential parameters on these structureschr('39') seismic response is the frequency content of the earthquakes. An index to represent frequency content, which represents frequen...
متن کاملEffect of Seismic wave scattering on the Response of Dam-Reservoir-Foundation Systems
Traditionally the foundation in a dam is modeled by a sub-structuring approach for the purpose of seismic performance analysis. The main disadvantage of sub-structuring approach is that it cannot be used for solving nonlinear dynamic problems. Therefore, in that case seismic response analysis must be carried out in time domain. Among the different earthquake input mechanisms the deconvolved ear...
متن کاملSeismic Behavior of Zoned Core Embankment Dam
The aim of this investigation is to study the dynamic behavior of a zoned core earth-fill dam. Due to lack of suitable clay materials, the Mamloo dam is designed as zoned core that is composed of three vertical zones including central lean clay (CL) core and two sides clayey gravel (GC) layers. Seismic behavior of dam was analyzed in two cases including homogenous clayey core and zoned core by ...
متن کاملThe Effect of Axial Force Variations on Nonlinear Modeling and Seismic Response of Reinforced Concrete Structures
In order to increase the accuracy of evaluating seismic response of structures, it is critical to conduct dynamic analyses based upon precise nonlinear models being as consistent as possible with the real conditions of corresponding structures. The concentrated plasticity model including one elastic element and two nonlinear spring elements at both ends has been considered within the research c...
