This book was released on 2011 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wide and concealed beam- narrow column joints constitute an important part of reinforced concrete building structural systems in Lebanon and the region. Because Lebanon and most of the region are seismically active, evaluating the performance of these joints when subjected to earthquake loads becomes particularly important. A two-part experimental investigation was carried out. Part 1 concentrated on evaluating the seismic response of wide and concealed beam-narrow column joints when designed and detailed under gravity load in accordance with local design and construction practices (as-built). Part 2 focussed on exploring means for improving the seismic performance of the joints through adequate reinforcement detailing, guided by the ACI Building Code. Aspects of the seismic behavior that were evaluated throughout the research program included: (i) mode of joint failure, (ii) flexural and shear capacity, (iii) bond performance of the reinforcing bars, (iv) lateral drift capacity or ductility, (v) stiffness degradation, (vi) energy absorption and dissipation capacity under cyclic loading, and (vii) shear capacity of the joint core. In the first part of the investigation (Part 1), four full-scale interior and exterior beam-column sub-assemblages were tested under quasi-static cyclic loading. All specimens experienced extensive shear cracking within the joint core, and at drift ratios between 4.0% and 4.5%, the joint core experienced damage beyond repair. It was concluded that unless detailed to prevent or limit shear failure, the as-built joints under investigation are significantly weak to be considered as part of the earthquake lateral-load-resisting system. In the second part of the investigation (Part 2), four additional full-scale joints were tested under quasi-static cyclic loading. The joints, referred to as earthquake-resistant joints, were similar to the four joints tested in Part 1, except that the reinforcement details were improved in part in accordance with ACI 318-08 provisions for earthquake-resistant structures. The joints satisfied some of the ACI Building Code design and steel detailing requirements, but still violated the dimension limitations specified in the same code or recommended by ACI-ASCE Committee 352-02. The corresponding joints displayed a considerably improved seismic performance, manifested by preventing or delaying joint shear failure, higher lateral load and drift capacities, lower stiffness degradation, larger energy dissipation capacities and stable overall hysteretic response when compared with the as-built joints. In addition to the main two parts of the investigation described briefly above, the potential of upgrading the seismic-resistant joints tested in Part 2 using a combination of epoxy injection for repairing the major cracks and carbon fiber reinforced polymers (CFRP) composites for strengthening was also explored and experimentally evaluated. The repair and strengthening procedure used in this study, which was carried out with minimum labor and cost, resulted in significant improvement of the structural performance of the damaged joints. This improved performance was manifested by substantial stiffness recovery, enhanced lateral load capacity and low strength degradation under large lateral drifts, controlled cracking and damage, and reasonable regain of energy absorption and dissipation capacity.

Available in PDF, EPUB and Kindle. Book excerpt: Earthquake engineering is the ultimate challenge for structural engineers. Even if natural phenomena involve great uncertainties, structural engineers need to design buildings, bridges, and dams capable of resisting the destructive forces produced by them. These disasters have created a new awareness about the disaster preparedness and mitigation. Before a building, utility system, or transportation structure is built, engineers spend a great deal of time analyzing those structures to make sure they will perform reliably under seismic and other loads. The purpose of this book is to provide structural engineers with tools and information to improve current building and bridge design and construction practices and enhance their sustainability during and after seismic events. In this book, Khan explains the latest theory, design applications and Code Provisions. Earthquake-Resistant Structures features seismic design and retrofitting techniques for low and high raise buildings, single and multi-span bridges, dams and nuclear facilities. The author also compares and contrasts various seismic resistant techniques in USA, Russia, Japan, Turkey, India, China, New Zealand, and Pakistan. Written by a world renowned author and educator Seismic design and retrofitting techniques for all structures Tools improve current building and bridge designs Latest methods for building earthquake-resistant structures Combines physical and geophysical science with structural engineering
