The load-testing of over a hundred bridges during the past nine years, varied from the extensive monitoring of all critical components in a bridge under test vehicles, to the measuring of the bridge accelerations under normal traffic. This report describes, in summary form, nearly all the bridge tests carried out until the end of 1977 and cites references of the detailed descriptions of the tests. Also given in the report is the brief description of the equipment that was employed during the testing operation. The report introduces bridge testing as a powerful, and sometimes the only, tool for determining the true safe load-carrying capacity of a bridge. It demonstrates that the evaluation based on conventional methods, quite often fails to predict the strength of a bridge by a large margin. Bridge testing is shown to be useful not only in determining the load carrying capacity of individual bridges but also in checking the validity of rational methods of evaluation, which after verification could be employed to realistically predict the safe load carrying capacity of similar existing bridges.
