In contrast to other infrastructure, there has been very limited cooperation between the industry and academia on developing the analytical tools for the design and evaluation of dams for seismic loading. This is mostly due to the complexity of the dam behavior as well as the size of these systems precluding the diffusion of academic information to the tools used by the practicing engineer due to time constraints. With the support of the Turkish National Sciences Foundation under the academia-industry cooperation grant programme, a commercial software suite is being developed including two major features developed in the scientific literature indispensable to the realistic design and evaluation of concrete dams. Soil-structure-reservoir interaction (SSI), with an extensive development in the scientific literature, is integrated in the first part of the software, allowing the realistic analyses of 2 and 3D dam systems. This feature enables the prediction of the correct damping response on the system simulating the wave propagation effects correctly in contrast to the finite element models used in the industry. On the other hand, the evaluation of the existing dams usually requires very large scale nonlinear finite element modeling out of the scope of the general purpose analysis tools. A parallel-explicit finite element engine is the second important feature of the suite enabling the user to predict the behavior of systems with excess of millions of degrees of freedom incorporating the cracking behavior. An easy to use graphical user interface, enabling the user to easily create the models and evaluate the analysis results, forms the top framework of the suite. This pre-post processor is dam-specific, designed for users to easily create and visualize dam and valley geometries, select common design inputs and analyses assumptions, as well as easily retrieve the specific outputs used for interpretation of the analyses results.

Development of a decision support system for optimal instrumentation of concrete faced rockfill dams
Arı, Onur; Yanmaz, Ali Melih; Department of Civil Engineering (2016)
In this study, an algorithm for optimal design of instrumentation systems for concrete faced rockfill dams was developed. The aim of this algorithm is to determine the number and the location of individual instruments for stress monitoring. It was intended to develop a user-friendly and flexible algorithm that would be applicable in reliable and economic design of instrumentation systems for concrete faced rockfill dams. The first developmental step was the generation of a model cross-section for a concrete...
DEVELOPMENT OF STRENGTH REDUCTION FACTORS FOR PERFORMANCE-BASED SEISMIC DESIGN OF BRIDGES IN FAR-FAULT SEISMIC REGIONS
Rabaia, Tareq Z. S.; Dicleli, Murat; Department of Engineering Sciences (2021-9)
In this thesis, a methodology to develop strength reduction factors for performance-based seismic design of bridges in far-fault seismic regions is presented. The presented methodology is mainly based on performing linear 5%-damped response spectrum analyses (RSA) and nonlinear time history analyses (NTHA) of bridge piers modeled as single degree of freedom (SDOF) systems. Bridge piers of both circular and rectangular sections are analyzed for wide ranges of various design parameters considering several sub...
Development of an applied element based tool for prediction of collapse behavior of concrete dam monoliths
Hassan Zada , Hamidullah; Arıcı, Yalın; Department of Civil Engineering (2020-9-24)
In this study, conducted with the support of TUBITAK under the grant 116M524, a software framework with a web-based graphical user interface is developed for the investigation of the seismic behavior of concrete gravity dams. Using a modified discrete element technique, one of the primary goals of the developed tool is to simulate extensive cracking on concrete dam monoliths followed by sliding, rocking and loss of stability. The graphical user interface for using this engine is prepared in HTML, Java...
Development of Fragility Curves for Single-Column RC Italian Bridges Using Nonlinear Static Analysis
Perdomo, Camilo; Monteiro, Ricardo; Sucuoğlu, Haluk (Informa UK Limited, 2020-05-07)
The main objective of this study is to assess the accuracy and suitability of Nonlinear Static Procedures (NSPs) in the development of analytical damage fragility curves for seismic risk assessment of large portfolios of Reinforced Concrete (RC) bridges. Seven NSP approaches, from widely used single-mode conventional pushover-based approaches to the more rigorous multi-mode conventional or adaptive pushover-based procedures are implemented. By systematically comparing fragility curve estimations in terms of...
Investigation of the relationship of seismic intensity measures and the accumulation of damage on concrete gravity dams using incremental dynamic analysis
Soysal, BERAT FEYZA; Binici, Barış; Arıcı, Yalın (2016-04-25)
Nonlinear analysis tools are gaining prominence for the design and evaluation of concrete gravity dams. The performance limits of concrete gravity dams within the framework of performance based design are challenging to determine in comparison to those used for the assessments based on linear elastic analyses. The uncertainty in quantifying the behavior of these systems and the strong dependence of the behavior on the ground motion play an important role. The purpose of the study is to quantify the damage l...
