This book was released on 2007 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wide-flanged concrete girders are increasingly being used for highway bridges in Wisconsin. The objective of this research was to understand the state of the art of non-metallic SIP forms and to develop design guidelines and performance specifications that can be used locally for the construction of highway bridge decks. Four major types of stay-in-place (SIP) forms using fiber reinforced concrete (FRC) or fiber reinforced polymer (FRP) materials were investigated: fiber reinforcements, grid reinforcements, bar reinforcements and pultruded profiles. The results were used to develop a model design and construction specification for non-structural, non-metallic, SIP forms in highway bridge decks.

This book was released on 1989 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents and presents results of a study to determine time-dependent behavior and relevant design criteria for simple-span precast, prestressed bridge girders made continuous. A questionnaire was used to determine current practice. Creep and shrinkage tests of steam-cured concrete loaded at an early age were made. Computer simulations were used to investigate the effects of time-dependent material behavior and variation in design parameters on the effective continuity for live load plus impact. The findings suggest that positive moment connections in the diaphragms at the piers are not required and provide no structural advantages. The findings also suggest that effective continuity for live load plus impact can vary from 0 to 100% dependent on the design parameters and timing of construction. Computer analyses were also used to determine an upper limit for the amount of negative moment reinforcement over the supports to insure full moment redistribution and attainment of maximum bridge strength. New computer programs were developed for simplified analysis to determine time-dependent effects and service moments. Recommendations for design procedures were presented and design examples given.

Available in PDF, EPUB and Kindle. Book excerpt: Despite their utilitarian nature, many bridges constitute the most visually stunning structures of our cities and towns. In Bridgescape: The Art of Designing Bridges, Frederick Gottemoeller brings the aesthetic aspects of bridge design within the grasp of all architects, engineers, and designers. This innovative approach challenges the reader to design and build bridges that are both functional and pleasing to the eye. Gottemoeller demystifies the creative process by breaking down the bridge into its most fundamental elements-line, form, and placement in the site, as well as color, texture, and ornamentation. The author shows how to plan bridges that take into account symbolism, historical meaning, and our ability to understand the visual world. But Bridgescape is more than an introduction to the aesthetic and engineering aspects of building a bridge. The author also discusses the dynamics of involving local authorities and the community in bridge design. From highway to pedestrian bridges, this book offers realistic and enlightening solutions for incorporating visually distinctive bridges within real-world situations and contexts. Working from the "skeleton" of the bridge-its girders, piers, and abutments-to its decorative features-color, carving, and texture-the author offers practical, easy-to-understand guidelines that can be applied to even the smallest of bridge design projects. Just a few key factors can profoundly enhance a bridge's appearance. Distinct from the technical books that separate architecture from engineering, Bridgescape offers a refreshing survey of the power of aesthetics in modern bridge design. A sixteen-page color insert enlivens the text, which is generously illustrated with over 280 photographs and drawings of bridges. Both engineers and architects will find Bridgescape an indispensable reference volume and an inspiring introduction to the aesthetic side of bridge engineering.

Approved as an alternate to the seismic provisions in the AASHTO LRFD Bridge Design Specifications. Differs from the current procedures in the LRFD Specifications in the use of displacement-based design procedures, instead of the traditional force-based "R-Factor" method. Includes detailed guidance and commentary on earthquake resisting elements and systems, global design strategies, demand modeling, capacity calculation, and liquefaction effects. Capacity design procedures underpin the Guide Specifications' methodology; includes prescriptive detailing for plastic hinging regions and design requirements for capacity protection of those elements that should not experience damage.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "This research aims at enhancing the service life of the prestressed concrete bridge girders, using fiber-reinforced polymer (FRP) composite shell on the lower flange to impede the ingress of deleterious elements into the concrete. The FRP shell would help to retard the resulting deterioration reactions and achieve more durable bridges for a considerably increased service life. The behavior of prestressed concrete bridge girders with FRP shells on the tension flange was investigated experimentally.The flexural characteristics of FRP shell and concrete interface along with the effect of the steel reinforcement ratio were studied experimentally. This FRP shell was bonded around the lower part of the concrete beams, constructed with four different reinforcement ratios. The beam specimens with the FRP shell showed a significant enhancement in their strength, stiffness and energy absorption capacities, as compared with the associated control beams. The flexural behavior of cast-in-place prestressed concrete beams with FRP shell was studied to examine the contribution of the bonded FRP shell to the strength, stiffness, ductility and energy absorption capacity of prestressed concrete beam specimens, for five different levels of prestressing. The initial cracking, yield and ultimate strengths of the beam specimens with FRP shell were significantly higher than those of the associated control beam specimens. The FRP shell and the prestressing force enhanced the strength and stiffness of the beams. The long-term durability of the FRP shell to act as a barrier against ingress of aggressive elements, such as moisture and chlorides into the proposed FRP shell-concrete system, was examined experimentally in a preliminary manner. Detailed tests on concrete specimens reinforced externally with FRP shells subjected to accelerated moisture and salt solution at control temperatures were performed. In addition, scanning electron microscopy (SEM) was used to determine the effects caused by aging, with time, temperature and chloride injection pressure. The FRP shell, acting as a barrier, showed a significant resistance against chloride ingress by significantly slowing down the chlorides ingress rate and the total amount of chlorides. For a prestressed concrete girder with an FRP shell, the accumulated time for chloride penetration and reaching the level of prestressing steel strands was predicted to be more than 135 years. These results suggest that the FRP shell is quite effective in improving the durability characteristics of prestressed concrete girders and can significantly extend their service life. " --
