Simulation of damage propagation on massiveconcrete structures, the overlapping lattice model v.s.The finite element approach

2017-10-11
The increase in the computational power enables the performance based assessment of very large structures like concrete gravity dams. These assessments are usually carried out with the traditional finite element tools. The continuum based formulation of these analyses in the absence of costly re-meshing operations cast doubt on the performance assessment of such massive plain concrete structures given the primary output assessed for these analyses should be the crack propagation and opening on the dam body. Smearing of the cracking in contrast to the discrete cracks on these systems, and the failure to simulate advanced stages of damage is a significant limitation for the finite element methods. On the other hand, a new approach in the form of overlapping lattice model shows a great potential for modeling of discrete cracking on plain concrete structures including the separation and rocking of individual components on the body. In this paper, the capabilities of the finite element tools for simulation of large damage on plain concrete structures are compared to the overlapping lattice model (OLM) approach. A set of three laboratory tests conducted with different types of loading were simulated using both tools. The limitations and capabilities of both approaches in predicting damage in the nature of crack propagation was established

Estimating the collapse limit state of concrete gravity dams within the framework of performance based design is challenging due to the uncertainty in modelling the response of these systems and the strong dependence of the behavior on the ground motion. In this context, the purpose of the study is to investigate the prediction capability of numerical tools in determining the collapse state of concrete gravity dams. The first tool used to this end is the classical finite element method with the smeared crac...

Estimating the collapse limit state of concrete gravity dams within the framework of performance based design is challenging due to the uncertainty in modelling the response of these systems and the strong dependence of the behavior on the ground motion. The purpose of the study is to investigate the seismic expected damage levels by using the overlapping lattice modeling (OLM) approach with incremental dynamic analysis (IDA) for two representative dam monoliths. OLM employs pin connected bar elements exten...

The consideratiOn of the dam-foundation-reservoir interaction is extremely important for estimating the seismic response of concrete gravity dams. Moreover, nonlinear analysis may be required for determining the possible risk associated with dams. In order to address these issues, DSI recently published the "Guidelines for Seismic Design of Concrete Dams". Authors who have contributed to the preparation of this document provide a perspective on the seismic safety/design of concrete dams and structural analy...
Dynamic response analysis of the machine foundations on a nonhomogeneous soil layer
Aşık, Mehmet Zülfü (1999-01-01)
Real modulus of elasticity of the soil usually increases with the depth of the soil due to the increase in overburden pressure. Therefore, incorporation of the effect of the soil inhomogeneity in the formulation to obtain the response of the machine foundations is an important and a necessary step. In this paper, equations that govern the dynamic behavior of the machine foundations and consider the inhomogeneity of the elastic foundation, particularly for Gibson type soil are derived by using variational pr...
