Available in PDF, EPUB and Kindle. Book excerpt: Abstract: There are a large number of prestressed concrete box beam bridges in service. Currently there are no satisfactory methods to rehabilitate deteriorated prestressed concrete box beam bridges. The standard operating procedure within government agencies is to monitor the deterioration until it is required to replace the entire superstructure of the bridge. This is not a cost effective solution because many of the box beam bridges have a small number of deteriorated beams. The design of a cost effective rehabilitation of a deteriorated prestressed box beam bridge is presented. Several options were considered, including the use of fiber reinforced polymer (FRP) reinforcement, replacing the superstructure, and replacing only the damaged beams, among others. The most cost effective and technically feasible option was determined and presented. The best solution for the rehabilitation of the prestressed concrete bridge was to remove and replace only the damaged beams. Removal and construction sequencing and details were developed that will prevent damage to adjacent box beams and allow the connection of the new box beams to the existing adjacent beams.

Available in PDF, EPUB and Kindle. Book excerpt: Precast prestressed concrete adjacent box beam bridges are widely utilized for short- and medium-span bridges throughout North America. However, a recurring issue with this bridge type is the deterioration of the shear key connection, resulting in substandard performance of the overall bridge system. This research investigated partial- and full-depth connection designs utilizing conventional non-shrink grout and ultra-high performance concrete (UHPC) by conducting full-scale structural testing. Quantitative measures to evaluate the connection performance that may assist in examining similar types of bridges are suggested in this study. A model to calculate the shear force in the connection is proposed, and both the shear and tensile stresses at the connection are analyzed. The findings can be used to assist in the design of connections for this bridge type. The performance of conventionally grouted and UHPC connections are presented and compared. It was found that the adjacent box beam bridges with UHPC connections can be a resilient bridge superstructure system, providing an innovative solution that can advance the state of the practice in bridge construction. This report corresponds to the accompanying TechBrief, Adjacent Box Beam Connections: Performance and Optimization.

This book was released on 2012 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A decommissioned, adjacent precast, prestressed concrete box girder bridge constructed in 1967 was load tested to destruction in August and September of 2010. The bridge, which crossed Paint Creek approximately nine miles (14.5 km) northeast of Washington Court House, Ohio, consisted of three simple spans, each 47 ft. 10 in. (14.6 m) long. Each span was comprised of nine, 21 in. (533.4 mm) deep by 36 in. (914.4 mm) wide prestressed concrete box beams for a total width of up to 27 ft. 4 in. (8.3 m) with a 15° left-forward skew. Prior to testing, the bridge appeared to be in good condition, with the vast majority of deterioration limited to concrete spalling from the exterior webs of the fascia girders. Of the three spans tested, this thesis details testing and analysis of the first two. In addition to environmental deterioration, the first span was damaged by researchers, whereas no additional damage was done to the second. Loads were applied via three, 350 kip (1557 kN) hydraulic cylinders supported by steel load frames. Test data collected from pressure transducers, wire potentiometers, and strain gauges were compared to predictions from a reinforced concrete modeling program. Beam capacity and bridge distribution factors were compared to values calculated from the AASHTO LRFD Bridge Design Specifications. Data analysis shows that the response of the bridge was predicted well by the analysis program for both low-level destructive and ultimate destructive loads. It was determined that bridge capacity could be found by summing the capacity of each individual beam, as long as the calculated capacity is reduced for the effects of damage. The bridge maintained its ability to transmit load between girders even after cracking of shear keys, indicating that steel tie rods play a major role in transmitting load from one beam to the next.

Available in PDF, EPUB and Kindle. Book excerpt: Segmental concrete bridges have become one of the main options for major transportation projects world-wide. They offer expedited construction with minimal traffic disruption, lower life cycle costs, appealing aesthetics and adaptability to a curved roadway alignment. The literature is focused on construction, so this fills the need for a design-oriented book for less experienced bridge engineers and for senior university students. It presents comprehensive theory, design and key construction methods, with a simple design example based on the AASHTO LRFD Design Specifications for each of the main bridge types. It outlines design techniques and relationships between analytical methods, specifications, theory, design, construction and practice. It combines mathematics and engineering mechanics with the authors’ design and teaching experience.

Download or read book Structural Evaluation of LIC 310 0396 Box Beams with Advanced Strand Deterioration written by and published by . This book was released on 2010 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four adjacent prestressed concrete box beams were removed from a decommissioned bridge and tested to destruction. The beams were 36 inches wide by 17 inches deep and had a span length of 37 feet 6 inches. Each beam contained fourteen, 1/2 inch diameter, stress relieved prestressed strands. All of the prestressed strands were arranged in one layer, which was located below the stirrups. One beam was in good condition, with the only visible deterioration being longitudinal cracking. One beam had three corroded prestressed strands visible and a large spalled segment which, when removed, exposed two additional prestressed strands. The remaining two beams were badly deteriorated, with spalled concrete exposing seven corroded prestressed strands. The provisions of the AASHTO LRFD Bridge Design Specifications, the AASHTO Standard Specifications, and the PCI Design Handbook were used to evaluate the loss of prestressing force. The measured prestressing force loss was closest to the AASHTO LRFD Bridge Design Specifications, but all three methods provided conservative estimates of prestressing force loss. The bridge had been designed using the AASHTO Standard Specifications. The provisions of the Standard Specifications were conservative in determining the ultimate loading for the undeteriorated beam. The provisions of the Standard Specifications were also conservative in determining the ultimate load for the deteriorated beam if the deteriorated strands were assumed ineffective. The deteriorated concrete box beams were all ductile and had final deflections exceeding L/50. The original bridge was rated using the test results. When following the provisions of the AASHTO Standard Specifications, the designed service loading for the bridge would have exceeded the ultimate loading of one deteriorated middle span beam. A failure of this beam would not have caused a progressive failure of the middle span under service loadings. Following the Load Factor Rating method for the middle span beams, the loadings exceeded the strength of the members. Therefore, load restrictions would have been required for the bridge had it not been decommissioned.

Download or read book Vehicle bridge Interaction Dynamics written by Yeong-Bin Yang and published by World Scientific. This book was released on 2004 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: The commercial operation of the bullet train in 1964 in Japan marked the beginning of a new era for high-speed railways. Because of the huge amount of kinetic energy carried at high speeds, a train may interact significantly with the bridge and even resonate with it under certain circumstances. Equally important is the riding comfort of the train cars, which relates closely to the maneuverability of the train during its passage over the bridge at high speeds.This book is unique in that it is devoted entirely to the interaction between the supporting bridges and moving trains, the so-called vehicle-bridge interaction (VBI). Finite element procedures have been developed to treat interaction problems of various complexities, while the analytical solutions established for some typical problems are helpful for identifying the key parameters involved. Besides, some field tests were conducted to verify the theories established.This book provides an up-to-date coverage of research conducted on various aspects of the VBI problems. Using the series of VBI elements derived, the authors study a number of frontier problems, including the impact response of bridges with elastic bearings, the dynamic response of curved beam to moving centrifugal forces, the stability and derailment of trains moving over bridges shaken by earthquakes, the impact response of two trains crossing on a bridge, the steady-state response of trains moving over elevated bridges, and so on.
