This book was released on 1975 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The load distribution on a 48.5-ft. span timber deck-steel girder bridge built to the Virginia Department of Highways and Transportation standard SS-4 requirements was investigated under two conditions. The first condition was concerned with the load distribution when the timber deck fasteners were tight and the second condition involved investigating the load distribution when the fasteners were loosened in several stages. The results of the study indicated that the live load stresses were of the same general order of magnitude and that the lateral load distribution was generally the same whether the deck plank fasteners were loose or tight. The load distribution factor currently used for the interior girders was found to be too high, whereas the procedure used for distribution of the load to the exterior girders was slightly low. It is recommended that consideration be given to using a load distribution factor of S for the evaluation of both the interior and exterior girders of timber deck-steel girder bridges similar to the one investigated. Compared to current procedures, this modification would result in a 20% reduction in the live load distribution to the interior girders and a 28% increase in the distribution to the exterior girders.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past few years the United States Department of Agriculture (USDA), Forest Products Laboratory (FPL), and the Federal Highway Administration (FHWA) have supported several research programs. This paper is a result of a study sponsored by FPL, with the objective of determining how truckloads are distributed to the deck panels of a longitudinal glued-laminated timber deck bridge. Currently, the American Association of State Highway and Transportation Officials (AASHTO) LRFD (load and resistance factor design) Bridge Design Specification provides live load distribution provisions for longitudinal glued-laminated timber deck-panel bridges. The AASHTO LRFD live load distribution provisions for longitudinal glued-laminated timber deck bridges were based on the assumption that the bridge deck behaves as one slab and ignores the discontinuity of the bridge deck panels. This study investigated this assumption by using analytical models that validated field test data from several in-service bridges and data from a full-scale laboratory test bridge. The analytical models accounted for the effects of the interface between the deck panels as well as the effects of the transverse stiffener beams on the distribution of the live- load. The analytical live load distribution results above were compared with both the AASHTO LRFD and AASHTO Standard Specifications.

Available in PDF, EPUB and Kindle. Book excerpt: Increased use of timber bridges in the U.S. transportation system has required additional research to improve the current design methodology of these bridges. For this reason, the U.S. Forest Service, Forest Products Laboratory (FPL), and the Federal Highway Administration have supported several research programs to attain the objective listed above. This report is a result of a study sponsored by the FPL, with the objective of determining how highway truckloads are distributed to girders of a glued-laminated timber bridge. The American Association of State Highway and Transportation Official (AASHTO) load and resistance factor design (LRFD) Bridge Design Specification provides live-load distribution provisions for glued-laminated girder timber bridges that were used in previous AASHTO Specifications. The AASHTO live-load distribution provisions were reviewed in this report. Field-test results were used to review the current AASHTO LRFD glued-laminated timber girder bridge-design specifications and to validate analytical results obtained by finite-element analyses. With the validated analytical models, parametric studies were performed to determine the worst-case live-load distribution factors that can be used to calculate the design moment and shear for glued-laminated timber girders. Simplified live-load distribution equations that can be used to determine these distribution factors were developed and are provided in this report. These equations take into account how load is distributed to the bridge girders, considering the effects of span length, girder spacing, and clear width of the bridge.
