Available in PDF, EPUB and Kindle. Book excerpt: In order to better utilize and develop timber structures in transportation, the United States government implemented several national programs starting in the early 1990's. Some of these programs were conducted by the United States Department of Agriculture Forest Service/Forest Products Laboratory and have attempted to develop a public awareness and effective use of timber and to advance timber technology for future use. One specific need identified was investigating the dynamic field performance of timber bridges due to vehicular loading. Currently, the American Association of State Highway and Transportation Officials (AASHTO) recommend a dynamic load allowance of 0.165 for timber bridges. Previously however, AASHTO did not include a load allowance for timber bridges. To quantify the appropriate code values, research was needed to determine the dynamic characteristics of timber bridges and to study their dynamic performance with respect to time and bridge condition. To fulfill this research need, five glued-laminated timber girder bridges and four longitudinal glued-laminated timber panel bridges were selected for testing. These bridges had also been tested previously in 1995 and 1996. The recent testing involved loading the structures dynamically with a fully loaded three axle dump truck to obtain dynamic response data. The information collected and discussed herein relates to the dynamic deflection, acceleration, and overall condition assessment for all nine bridges. The results of the individual bridges are also compared with each other to determine the validity of the current AASHTO recommendations and to develop better design standards. In general, the nine bridges tested were found to have fundamental frequencies between 5Hz and 11Hz as well as a dynamic load allowance less than 0.25. The bridges found to have dynamic amplifications above specified code values were also found to have physical characteristics (i.e., rough entrances) that caused the excessive dynamic amplification values.

This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to state department of transportation and consulting bridge, structural, and research engineers. The synthesis describes the current state of the practice for determining dynamic impact factors for bridges. Information for the synthesis was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search using domestic and foreign sources. This report of the Transportation Research Board documents relevant background and recent information with regard to vehicular dynamic load effects on bridges. It provides details on the basic concepts of bridge dynamics, including identification of the main variables affecting bridge dynamic response. In addition, current code provisions for accounting for vehicular dynamic load effects for new bridge design and load evaluation of existing bridges are reported, including a discussion on the background of the provisions. Finally, a discussion of observed field problems associated with vehicular dynamic load effects, as obtained from the survey, are included.
