Measurement of Traffic Loads and Stresses in Three Steel Bridges

摘要

This report, one of a series of three supplementary reports, describes the British contribution to a joint European research project to investigate dynamic loads on steel bridges. The aim of the project was to provide measured data on traffic loading which will be available for future studies of design methods and rules, and also to investigate the dynamic stresses produced in bridges by traffic loading. Measurements were made at three bridges: Forth, Wye and Manchester Road(Isle of Dogs). Strain gauges were installed on parts of the structures subjected to high traffic induced stresses, and dynamic weighbridges and vehicle detectors were installed close by. This report describes the measurements that were made and the methods of making them. Some analyses of the data collected and a review of the literature are contained in the other two reports in the series. The project has provided more detailed information on traffic characteristics than has been available previously, and information on the stresses produced in steel bridge structures by traffic.
