Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a 30 month investigation at Lehigh University during which an FHWA WIM system was redesigned and used to acquire and process simultaneous truck weight plus bridge response data from 19,402 trucks crossing 4 inservice bridges in Pennsylvania. The new system is designated the WIM+RESPONSE system in the report. The WIM+RESPONSE system is capable of acquiring and processing data to provide information on simultaneous bridge loading and response including GVW distributions for the four inservice bridges plus stress range distributions, strain rates, and maximum stresses at 16 locations on each of the 4 bridges. Girder stresses are compared with AASHTO design stresses and with stresses from a detailed finite element analysis of the superstructure.

This book was released on 2011 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Report 683: Protocols for Collecting and Using Traffic Data in Bridge Design explores a set of protocols and methodologies for using available recent truck traffic data to develop and calibrate vehicular loads for superstructure design, fatigue design, deck design, and design for overload permits. The protocols are geared to address the collection, processing, and use of national weigh-in-motion (WIM) data. The report also gives practical examples of implementing these protocols with recent national WIM data drawn from states/sites around the country with different traffic exposures, load spectra, and truck configurations. The material in this report will be of immediate interest to bridge engineers. This report replaces NCHRP Web-Only Document 135: Protocols for Collecting and Using Traffic Data in Bridge Design. Appendices A through F for NCHRP Report 683 are available only online.

This book was released on 1992 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two main objectives of the present study were to: (1) demonstrate the advantages of using the Weigh-in-Motion and Response (WIM+R) system to evaluate the fatigue life of existing bridges and (2) introduce pattern recognition methods in the analysis of WIM+R data. Four steel girder bridges were instrumented to obtain strain data at fatigue critical details, and at sections of maximum strain to compute the gross vehicle weight (GVW) of each truck. Two were simple spans, and two continuous spans. A comparative study of three of the four alternatives suggested by AASHTO showed that the fatigue life computed with direct measurements of the stress ranges were greater than those computed with the simplified approaches. The effect of secondary cycles was negligible for the four bridges. The damage equivalent secondary cycle factor for fatigue was defined. The applicability of three pattern recognition methods for WIM+R was investigated. The dynamic time warping, hidden Markov model, and feed forward neural network methods can classify trucks with the measured strain patterns alone.
