Book Synopsis Seismic Design and Performance of Concrete Multi-column Bents for Bridges by : Sri Sritharan
Download or read book Seismic Design and Performance of Concrete Multi-column Bents for Bridges written by Sri Sritharan and published by . This book was released on 1997 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the seismic design and performance of two concrete multi-column bents. The first unit contained a precast fully prestressed cap beam while the second unit was designed with a reinforcement concrete cap beam. A mix of conventional and headed reinforcement and mechanical couplers were used in detailing the cap beam of the second unit. Tests were performed with the objective of examining the most efficient cap beam/column details, which were established in previous joint tests, under the maximum feasible shear demand. Tests results showed that both units produced a satisfactory response when subjected to simulated seismic loading.

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.

Book Synopsis Seismic Behavior and Retrofit of Older Reinforced Concrete Bridge T-joints by : Laura N. Lowes
Download or read book Seismic Behavior and Retrofit of Older Reinforced Concrete Bridge T-joints written by Laura N. Lowes and published by . This book was released on 1995 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of experimental tests investigating the seismic response of reinforced concrete beam-column T-joints was recently completed at the University of California, Berkeley. The evaluated connection was representative of an interior beam- column joint from a multi-column bridge frame built in the late 1950's. Three one-third scale models, representing the as-built connection and two retrofit connections, were tested. The results of this research project are an improved understanding of the seismic behavior of lightly reinforced bridge T-joints as well as verification of a design procedure for retrofitting this type of connection.

Download or read book Upgrading Bridge Outrigger Knee Joint Systems written by Božidar Stojadinović and published by . This book was released on 1995 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The collapse of the Cypress Street Viaduct during the 1989 Loma Prieta earthquake emphasized the vulnerability of elevated freeway bridge structures. A part of the joint Caltrans and University of California at Berkeley research project, initiated after the earthquake, focused on the outrigger knee joint systems found in bents of elevated freeway bridges. The investigation had two principal goals: to evaluate the behavior of the existing outrigger knee joint systems under a combined transverse and longitudinal loading and to devise and experimentally verify strategies for seismic upgrading of existing outrigger knee joints. The experiments on two half-scale as-built models confirmed the poor performance of existing outrigger knee joint systems observed after the earthquake. Two seismic upgrading strategies, a "ductile" and a "strong" strategy, were proposed and tested on prototype specimens. The "strong" strategy was chosen for the final seismic upgrade design. The variation of this strategy using a steel jacket, was recommended in the seismic upgrade design guidelines.

Book Synopsis Design and Response of Lower-level Beam-column Joints in Ductile Reinforced Concrete Double-deck Bridge Structures by : Mazzoni, Silvia
Download or read book Design and Response of Lower-level Beam-column Joints in Ductile Reinforced Concrete Double-deck Bridge Structures written by Mazzoni, Silvia and published by . This book was released on 1997 with total page 252 pages. Available in PDF, EPUB and Kindle. 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.
