This book was released on 2014 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: After an earthquake event it is the responsibility of the engineers to decide if the bridge structure is safe for the traffic flow, requires repair or needs to be replaced completely depending on the damage level. Effective, economical and timely repair of Reinforced Concrete (RC) bridges after a seismic event is crucial to avoid traffic congestion and lengthy detours. Fiber Reinforced Polymer (FRP) composite laminates are one of few options with several advantages. Use of FRP jackets in structural engineering is gaining interest in applications such as strengthening weak structural elements, improving the existing structure capacity to resist increased loads due to change in use of structure and retrofitting structural elements for seismic upgrades. The study presents shaking table experimental investigation to evaluate the use of FRP for repairing RC bridge columns with circular cross-sections. Two 1/4-scale RC columns were tested in as-built configuration. Both tests had identical geometry and reinforcement details except for the spacing of the transverse reinforcing bars. One column had closely spaced hoops satisfying code requirements and the other had larger spacing, representing a shear-critical column. The test specimens were subjected to a series of horizontal and vertical excitations on a shaking table and experienced moderate to high damage. The damaged columns were subsequently repaired with unidirectional FRP composite laminates and subjected to the same set of earthquake excitations. The obtained experimental data showed that the repaired columns achieved higher strength and ductility with lower residual displacements compared to the as-built ones contributing to the resiliency of the bridge system. A three-dimensional (3D) Finite Element (FE) model was developed and calibrated using the experimental test results. A bilinear confined concrete model was adopted to model the constitutive relationship of the FRP confined concrete without explicitly modeling the FRP composite jacket. Due to variability of the material properties, several calibration parameters were studied to develop a reliable FE model. The results of the dynamic FE analysis showed great potential for 3D modeling of the repaired test specimens. From this study, it is concluded that the used FRP composite laminates represent a viable solution for the effective and rapid repair of damaged RC bridge columns. A parametric study was conducted to evaluate the horizontal force, deformation, and confining strain response of the retrofitted RC bridge columns using the computational model. The response of the FE models with different number of FRP plies in the jacket was investigated. The analytical results suggested that increasing the number of FRP plies in the jacket significantly changed the confining strains response of the confined cross-section but the global force-deformation was not significantly affected.

Book Synopsis Post-earthquake Traffic Capacity of Modern Bridges in California by : Vesna Terzic
Download or read book Post-earthquake Traffic Capacity of Modern Bridges in California written by Vesna Terzic and published by . This book was released on 2010 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The test results were then used to calibrate a finite element model of a bridge column. This bridge column model was incorporated into a hybrid model of a typical California overpass bridge and tested using the hybrid simulation technique. The finite element model of the typical California overpass bridge was validated using the data from hybrid simulations. The validated model of the typical bridge was used to evaluate its post-earthquake truck load capacity in an extensive parametric study that examined the effects of different ground motions and bridge modeling parameters such as the boundary conditions imposed by the bridge abutments, the location of the truck on the bridge, and the amount of bridge column residual drift. The principal outcomes of this study are the following findings.
Book Synopsis Preliminary Seismic Analysis and Design of Reinforced Concrete Bridge Columns for Curved Bridge Experiments by : Nathan W. Harrison

This book was released on 2011 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a Federal Highway Administration (FHWA) sponsored research project to study highway system resilience, a 40 percent scale curved steel plate girder bridge is to be constructed and subjected to earthquake simulation at the Large Scale Structures Laboratory on the University of Nevada, Reno (UNR) campus. The 145 foot long bridge model is to have three-spans, supported on two single-column bents with hammer-head pier caps, and have a subtended angle of 104°. The purpose of the shake table testing is to study the seismic system behavior of the bridge as well as additional bridge components including; conventional columns, isolation, ductile-cross frames, abutment behavior, and the seismic behavior of bridges including the effects of live load. Ultimately design recommendations will be developed from this research. The research presented in this document is the results of preliminary analysis and design of conventional reinforced concrete bridge columns and substructure elements as part of the larger project to examine global seismic behavior of the scaled bridge model. In order to prepare for seismic testing of the scaled bridge model, extensive pre-experimental numerical analysis was performed. Finite element models were developed using SAP2000 and non-linear time-history analysis was performed to investigate the seismic response of the bridge model. Analytical bridge models were analyzed using both 16-inch and 20-inch column diameters and various abutment support conditions. The models were subjected to two levels of horizontal bidirectional earthquake excitation representing a design level earthquake and a large amplitude earthquake intended to cause column failure. Using the results from the analysis, preliminary construction plans were prepared for one set of columns and the adjacent substructure components using the provisions from the AASHTO Guide Specifications for LRFD Seismic Bridge Design. In addition to the investigation into column performance, a parametric study was performed to determine axial response of the bearings at both the abutments and piers when subjected to seismic loading. The numerical analysis showed that system effects due to superstructure-substructure interaction can cause column flexural response that is typically not observed with stand-alone column tests. The effects of bridge horizontal curvature was shown to have a significant impact on the axial performance of the bearings in which the response was not uniform for all bearing at one support location. As a component of the analysis and design, two strut-and-tie models were developed to provide adequate joint detailing in order to ensure capacity protection of the column-to-bentcap connection under multiple cycles of seismic loading.

This book was released on 2019-09-19 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resilient buildings and cities are in the center of common interests in modern academic communities for science and engineering related to built environment. Resilience of buildings and cities against multidisciplinary risks, e.g. earthquakes, strong winds, floods, etc., is strongly related to the sustainability of buildings and cities in which reduction of damage during a disaster and fast recovery from the damage are key issues. The reduction of damage is related to the level of resistance of buildings and the time of recovery is affected by the amount of supply of damaged members, assurance of restoration work, etc. Robustness, redundancy, resourcefulness, and rapidity are four key factors for supporting the full realization of design and construction of resilient buildings and cities. This research topic gathers cutting-edge and innovative research from various aspects, e.g. robustness of buildings and cities against earthquake risk, structural control and base-isolation for controlling damage risks, quantification of resilience measures, structural health monitoring, innovative structural engineering techniques for higher safety of buildings, resilience actions and tools at the urban scale, etc.
