This book was released on 2012 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: "TRB's National Cooperative Highway Research Program (NCHRP) Report 725: Guidelines for Analysis Methods and Construction Engineering of Curved and Skewed Steel Girder Bridges offers guidance on the appropriate level of analysis needed to determine the constructability and constructed geometry of curved and skewed steel girder bridges. When appropriate in lieu of a 3D analysis, the guidelines also introduce improvements to 1D and 2D analyses that require little additional computational costs."--Publication information.

Available in PDF, EPUB and Kindle. Book excerpt: The current thesis presents the finite element results of a parametric study to accurately evaluate the effect of skewness on wheel load distribution in steel g irder highway bridges. The finite element method is used to investigate the effect of span length, girder spacing, and skewness, on one-span simply supported, two-lane, th reelane, and four-lane steel girder bridges. Five span lengths and three girder spacings are examined in combination with six skew angles, for a total of 270 bridges analyze d and reported in the study. Various positions of the design trucks are assumed, longi tudinally and transversally, in order to produce maximum bending moments. The finite eleme nt modeling consists of shells and frames, for concrete slab and steel girders, res pectively, and composite action between slab and girders is assumed. The finite element pro gram SAP2000 is used in the analysis, and the longitudinal bending moments are comput ed and corresponding wheel load distribution factors on the girders are reported an d discussed for various skew angles. The finite element analysis results for skewe d bridges are compared to the reference straight bridges as well as to the America n Association for State Highway and Transportation Officials (AASHTO) Standard Specifications and LRFD procedures. This study will assist bridge engineers in performing realistic analysis and design of simply supported, multi-lane, skewed steel girder bridges as well as evaluate the load carrying capacity of existing struct ures.

Download or read book Single Lane Live Load Distribution Factor for Decked Precast/prestressed Concrete Girder Bridges written by John Zhongguo and published by . This book was released on 2005 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The live load distribution factor (DF) equations provided by AASHTO-LRFD for the decked precast/prestressed concrete (DPPC) girder bridge system do not differentiate between a single or multilane loaded condition. This practice results in a single lane load rating penalty for DPPC girder bridges. The objective of this project is to determine DF equations which accurately predict the distribution factor of the DPPC girder bridge system when it is only subjected to single lane loading. Eight DPPC girder bridges were instrumented. Each bridge was loaded with a single load vehicle to simulate the single lane loaded condition. The experimental data was used to calibrate 3D FE models and 2D grillage models of the DPPC girder bridge system. The calibrated models were used to conduct a parametric study of the DPPC girder bridge system subjected to a single lane loaded condition. Two sets of new equations that describe the single lane loaded distribution factor for both shear and moment forces of these bridges are proposed and compared with AASHTOLRFD DF equations.

Download or read book Development of Design Criteria for Simply Supported Skew Slab-and-girder Bridges written by Hendrik Jacobus Marx and published by . This book was released on 1986 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastic analyses, using the finite element method, were done on 108 single span skew slab-and-girder bridges. Each structure had 5 girders and stiffnesses were representative of bridges with pretensioned I-girders or steel I-beam. Spans ranged from 40 to 80 ft, girder spacings from 6 to 9 ft, and the skew angle from zero to 60 degrees. The loadings were multiple point loads representing two HS20 AASHTO vehicles, and the loads were positioned to produce maximum bending moments in the girders. Convergence studies to evaluate the precision of the finite element models were also done, and comparisons were made with the results of other studies. An extensive parametric study was done to determine the most important variables and to gain an understanding of the response of the skew bridge. Expressions for the design moments in interior and exterior girders were then developed. These take into account the span and spacing of girders, the stiffness of the girders relative to the slab stiffness, and the angle of skew. The format is the use of the static moment for a girder, with modifications to this moment based on girder span and spacing, slab to girder stiffness ratio, and skew angle. A similar study was done to obtain factors for the calculation of deflections, starting with the deflection of a simple beam.
