Dr. Reşat A. Oyguç is an associate professor in the Department of Earthquake Engineering, Institute of Disaster Management, Istanbul Technical University, Turkey. He received his MSc from Yıldız Technical University, Turkey, and a Ph.D. in Structural and Earthquake Engineering from Istanbul Technical University. His research doctorate was on the seismic capacity assessment of irregular structures using adaptive pushover procedures. He investigates the response of complex networks and structures under extreme loading conditions. He has also undertaken many studies on the safety assessment of structures and the evaluation of post-earthquake failures. Specifically, Dr. Oyguç works on nonlinear inelastic dynamic response simulation for infrastructures. His recent research includes a seismic performance assessment of a nuclear reactor building under multiple earthquake excitations considering the degradation effects.

Structural integrity and failure assessment have been considered by many fields of engineers as it is a multi-disciplinary concept. The assessment procedure vitally ensures that structural elements will remain functional throughout their service lives. Structural failure refers to the loss of structural integrity by means of loss at the component- or system-level elements. The main concern of integrity assessment is that a structural failure may be avoided at the service level by designing the structure to withstand its designated loads. Hence, for satisfactory structural performance, structural safety, failure, and interaction between them should be considered throughout the design and analysis stages. This book is a collection of chapters that provide the researcher with a comprehensive perspective on structural integrity and its sub-disciplines.

Structural Modeling and Dynamic Analysis of a Nuclear Reactor Building

By Evrim Oyguc, Abdul Hayır and Resat Oyguc

Increasing energy demand urge the developing countries to consider different types of energy sources. Owing the fact that the energy production capacity of renewable energy sources is lower than a nuclear power plant, developed countries like US, France, Japan, Russia and China lead to construct nuclear power plants. These countries compensate 80% of their energy need from nuclear power plants. Further, they periodically conduct tests in order to assess the safety of the existing nuclear power plants by applying impact type loads to the structures. In this study, a sample third-generation nuclear reactor building has been selected to assess its seismic behavior and to observe the crack propagations of the prestressed outer containment. First, a 3D model has been set up using ABAQUS finite element program. Afterwards, modal analysis is conducted to determine the mode shapes. Nonlinear dynamic time history analyses are then followed using an artificial strong ground motion which is compatible with the mean design spectrum of the previously selected ground motions that are scaled to Eurocode 8 Soil type B design spectrum. Results of the conducted nonlinear dynamic analyses are considered in terms of stress distributions and crack propagations.
