Book excerpt: A research program of field and laboratory tests to study the seismic response of reinforced concrete double-deck freeway structures has been concluded at the University of California, Berkeley. The program had three phases of testing. This report describes the research findings of the third phase of the program, which focused on the design criteria for beam-column joints in new ductile double-deck freeways. Two one-third scale test specimens representing the lower-level beam-column joint in a double-deck bridge structure were built and tested in the laboratory. The test specimens were designed according to current design criteria. The two test specimens differed in the strength of the members framing into the joints. The scope of the tests was to determine the response of the joints when subjected to unidirectional and bidirectional load cycles and compare the response to the different levels of maximum joint shear stress demands.

This book was released on 1996 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete bridge joints in California were detailed with no shear reinforcement in the 1950s. The probable consequence of such poor detailing was demonstrated on an as-built tee (interior) joint from the Santa Monica Viaduct in Los Angeles. When a redesign of this joint was considered with the conventional design methods based upon the maximum joint shear forces, it resulted in a considerable amount of joint reinforcement, causing congestion of steel within the joint. This has been identified as a major construction problem in concrete bridge construction. Three redesigns of the prototye joint were sought with the objective of reducing the amount of reinforcing steel within the joint, thereby ensuring constructability. In all three designs, force transfer models were employed in determining the appropriate amount of joint reinforcement rather than using the joint shear forces as the design parameter. When the cap beam was designed with full prestressing, it was also shown that precast construction can be adopted as an alternative to cast-in-place construction for building multi-column concrete bents. The details of the joint design, seismic performance of all three redesigned units and some design recommendations are presented in this report.

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.
