“…Routine scalable parameters of ground motion, which can be selected as IM, include Peak Ground Acceleration (PGA), peak ground velocity, spectral acceleration, spectral velocity, Arias Intensity, speci c energy density, and maximum incremental velocity [16,38]. It should be indicated that the rst four items are frequently applied to seismic evaluation of dams through IDA [12,13,38,39]. Choosing S a (5%; T 1 ) as IM, by Alembagheri and Ghaemian, has made a lower coe cient of variation in all ranges of DMs in IDA curves [12].…”

“…Choosing S a (5%; T 1 ) as IM, by Alembagheri and Ghaemian, has made a lower coe cient of variation in all ranges of DMs in IDA curves [12]. In another research performed by Soysal et al, it was revealed that PGA and spectral velocity at the rst mode (S v (5%; T 1 )) played a signi cant role compared to the other IMs in the prediction of cumulative damage states [39]. Since the purpose of this study is the assessment of cumulative damage states, PGA is selected as the main IM parameter.…”

Determination of limit-states for near-fault seismic fragility assessment of concrete gravity dams

Fragility curve, based on the Performance-Based Earthquake Engineering (PBEE), is a fundamental tool for assessing the probabilistic seismic performance of concrete gravity dams. Determination of the dam Limit-States (LSs) is necessary for estimation of fragility curve. In this research, four LSs in seismic performance of massive structure have been utilized for Pine Flat dam. To address this, the Incremental Dynamic Analysis (IDA) method has been applied to the integrated dam-reservoir nite-element model. Evaluation of seismic behavior, demand and capacity of the tallest monolith has been done by implementing IDA. A new comprehensive method in terms of IDA and statistical analysis has been used for determination of each de ned LS based on the certain value of the Engineering Demand Parameter (EDP). To assess probabilistic performance of the dam, the exceeding probability of the LSs curves has been developed at various intensity measures based on the tree EDPs. It was found that the de ned LSs had the capability indeed to be used in probabilistic framework.

The purpose of this joint contribution is to study the maximum dynamic load concrete dams can withstand. The so-called "dynamic capacity functions" for these infrastructures seems now technically and commercially feasible thanks to the modern finite element techniques, hardware capabilities, and positive experiences collected so far. The key topics faced during the dynamic assessment of dams are also discussed using different point of view and examples, which include: the selection of dynamic parameters, the progressive level of detail for the numerical simulations, the implementation of nonlinear behaviors, and the concept of the service and collapse limit states. The approaches adopted by local institutions and engineers on the subject of dam capacity functions are discussed using the authors' experiences, and an overview of time and resources is outlined to help decision makers. Three different concrete dam types (i.e., gravity, buttress, and arch) are used as case studies with different complexities. Finally, the paper is wrapped up with a list of suggestions for analysts, the procedure limitations, and future research needs.

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 extending over a predefined horizon to discretize the continuum similar to the concept used in peridynamics. The constitutive model of concrete was calibrated by using tension tests prior to the dam simulations. The most important advantage of the OLM approach was the ability of the simulations to capture the discrete crack propagation in a much better. Nonlinear finite element analyses by using a smeared rotating crack model for concrete were also conducted to compare the estimations of OLM. The results of IDA showed that initial cracking occurred at the dam base followed by the inclined cracking of the dam body resulting in significant damage. A strong dependence of the damage patterns on the ground motion was noted. OLM estimations of crack lengths tended to be longer and more discrete as opposed to the more diffused and shorter cracks obtained with the nonlinear finite element simulations. Results demonstrate the promising nature OLM to capture dynamic crack propagation in concrete media.
