Comparison of the expected damage patterns from two- and three-dimensional nonlinear dynamic analyses of a roller compacted concrete dam

2014-03-04
The seismic performance of the tallest roller-compacted concrete gravity dam in Turkey is investigated in this study. For this purpose, two- and three-dimensional nonlinear dynamic finite element analyses were conducted to investigate the expected damage under simulated ground motions. Based on the results of finite element simulations, it was found that the three-dimensional behaviour of the dam is substantially different from the idealised two-dimensional monolith behaviour, even for a dam having monoliths separated with transverse joints. In addition, it was determined that in order to limit the cracking at the base of the dam, higher strength grout-enriched concrete must be used on the upstream and downstream faces. This study demonstrates the importance of three-dimensional modelling for gravity dams built in relatively narrow valleys along with the significance of the modelling of the nonlinear response for seismic performance assessment.

Soysal Albostan, Berat Feyza; Arıcı, Yalın; Binici, Barış; Tuncay, Kağan (2017-10-13)
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...

Inspired from the simplified single degree of freedom modeling approach used in the preliminary design of concrete gravity dams, a pseudo-dynamic testing method was devised for the seismic testing of a concrete gravity dam section. The test specimen was a 1/75 scaled section of the 120-m-high monolith of the Melen Dam, one of the highest concrete gravity dams to be built in Turkey. The single degree of freedom idealization of the dam section was validated in the first stage of the study using numerical simu...
Comparison of loads in Turkish earthquake code with those computed statistically
Firat, Fatih K.; Yücemen, Mehmet Semih (2015-05-01)
In this study, earthquake loads are investigated statistically and compared with the nominal earthquake loads calculated according to the Turkish Earthquake Code, namely: "Specifications for Structures to be Built in Earthquake Areas". For this purpose, the "actual" mean load values estimated from statistical methods and the nominal load values computed according the Seismic Code are compared, with respect to some variations in the basic parameters, such as the importance factor, building height, site coeff...

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...
