Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2015 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eccentrically braced frames (EBFs) are very effective lateral load resisting systems against earthquakes because of their hybrid behavior that includes great stiffness corresponding to the bracing actions, and considerable ductility owing to the inelastic activity of a small part of the floor beam called link. Current capacity design approach of EBFs is to confine the inelastic behavior of the frame primarily to the link such that other members remain essentially in elastic range. Limited research works are available in the literature studying the behavior of multi-storey EBFs designed according to the current Canadian seismic provisions. This thesis was aimed to study seismic performance of EBFs through nonlinear time history analysis (NLTHA) of three 4-, 8- and 14-storey chevron eccentrically braced frames. The selected EBFs were subjected to real and artificial ground motion records scaled to match the response spectrum of Vancouver. All the EBFs, designed according to current capacity design provisions, exhibited excellent seismic performance in terms of stiffness, strength, and ductility. It was observed that the inelastic link rotations of all EBFs were lower than the design limit of 0.08 rad, except for the two upper floors in 14-storey EBF where the link rotation slightly exceeded the limit. Seismic analysis also showed that maximum inelastic link shear forces exceeded the values recommended in design for many earthquake records. Although NLTHA can precisely estimate structural seismic responses, it requires high computational demands making it impractical for engineering design offices. On the other hand, the conventional pushover analysis does not consider contributions of higher modes to the structural responses and thus it often does not provide good estimation of seismic responses for taller buildings. Capacity-Spectrum Method (CSM) and modal pushover analysis (MPA) are two simple nonlinear static methods that have been proposed and recently used for seismic performance evaluation of few lateral load-resisting systems. This research further studies the application of CSM and MPA as alternatives for rigorous NLTHA to estimate seismic performance parameters of EBFs. The three selected EBFs were analyzed using MPA and CSM and the results were compared with nonlinear seismic analysis results. It was observed that both CSM and MPA predicted the peak top displacements of EBFs with sufficient accuracy.

This book was released on 2019 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
