Book Description
This thesis presents the results of a finite element study of the behavior of the shear links with reduced web sections subjected to cyclic and monotonic loading protocols, for use in seismic-resistant steel Eccentrically Braced Frames (EBFs). The capacity design philosophy for EBFs relies on the principle that the link, where inelastic deformation is intended to occur in an earthquake, must be the weakest element in the frame. One approach to satisfying capacity design requirements of EBFs is to decrease the strength of the links. Removing some portion of the link web is one method to reduce the shear capacity of the link. Twenty-one finite element models were analyzed under cyclic and monotonic loading protocols. Finite element models were based on a W18x40 shear link, without web holes, tested in an actual experiment. Modeling techniques and material definitions were validated using the same experimental findings. The finite element shear link models with various hole patterns, locations, and percent web removal were then analyzed to investigate the effect of removing material from the web on the behavior of the shear link in terms of strength and rotation capacity. This study suggests that shear links with reduced web sections provide a potentially viable method to reduce link shear strength

Book Description
Eccentric braced frames have been a topic of research in seismic design over the past twenty years. The idea of eccentric bracing is a relatively new method used in practice to satisfy seismic design requirements. They have been proven to give reliable results in tests using simulated earthquake events, as well as provide an economical advantage over other framing methods. Two one-story eccentric braced frame models were created using computer generated finite element analysis. The example chosen for this study are discussed further. The maximum shear stress distribution in the link beam of the frame, using finite element analysis, will be investigated herein. The results of the shear stress produced gives insight to shear forces developed in the link beam of eccentric braced frames. The results of shear forces produced are compared with those calculated by structural engineers using commonly used hand calculated equations.

Book Description
Providing real world applications for different structural types and seismic characteristics, Seismic Design of Steel Structures combines knowledge of seismic behavior of steel structures with the principles of earthquake engineering. This book focuses on seismic design, and concentrates specifically on seismic-resistant steel structures. Drawing on experience from the Northridge to the Tohoku earthquakes, it combines understanding of the seismic behavior of steel structures with the principles of earthquake engineering. The book focuses on the global as well as local behavior of steel structures and their effective seismic-resistant design. It recognises different types of earthquakes, takes into account the especial danger of fire after earthquake, and proposes new bracing and connecting systems for new seismic resistant steel structures, and also for upgrading existing reinforced concrete structures. Includes the results of the extensive use of the DUCTROCT M computer program, which is used for the evaluation of the seismic available ductility, both monotonic and cyclic, for different types of earthquakes Demonstrates good design principles by highlighting the behavior of seismic-resistant steel structures in many applications from around the world Provides a methodological approach, making a clear distinction between strong and low-to-moderate seismic regions This book serves as a reference for structural engineers involved in seismic design, as well as researchers and graduate students of seismic structural analysis and design.
