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.

This book was released on 2011 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beam-column joint is considered a critical region in a structure when subjected to seismic load. Past earthquakes have shown that many of these structures behaved poorly and exhibited a combination of brittle failure at the joint and pullout of the beam longitudinal steel, leading to a rapid degradation of the joint and a precursor to a catastrophic collapse of a structure. Review of existing structures built prior to 1976 have determined concrete joints typically have little or no transverse reinforcement, discontinuous bottom beam reinforcement with insufficient embedment depth, and a common occurrence of column lap splice above the beam-column interface. Previous studies of rebar bond slip behavior, joint shear response, and joint interface - shear response were reviewed culminating in a study of various joint models simulating the behavior of deficient concrete beam-column joint subjected to a seismic load. An experimental test program consisting of three specimens was developed to test the behavior of deficient concrete beam-column joints. Specimen AB1 consists of deficient shear reinforcement at the joint, and will be tested to evaluate the behavior of a deficient reinforced concrete beam-column joint solely on insufficient shear reinforcement. Specimen AB2 is designed according to pre-1976 building standard and lacks sufficient rebar embedment of longitudinal beam reinforcement at the joint and has no shear reinforcement within the joint area. Specimen ACI318 is designed per the specifications of ACI 318-08, and will be used as the control specimen. Experimental results of the test program will eventually be applied as a baseline comparison to proposed state-of-the-art retrofit schemes aimed at enhancing the overall seismic performance of deficient reinforced concrete beam-column joints.
