MODELLING PROBLEMS IN SHORT-SPAN BRIDGES AND THE BASICS OF LOAD TESTING

Problems in modelling short span bridges arise from the complexity of the support systems involved. A strength higher than that calculated may be due to a) materials strengths, b) design assumptions, or c) the presence of other coexisting support systems. Examples of support systems for bridges are discussed. Factors considered include soil- structure interaction, fill effects, bearing restraint and end restraint. Suitable applications for load testing are discussed. Supplementary and proving loading tests are distiguished and the procedures involved in each outlined. Loading methods are described. Measuring procedures, lane by lane loading and costs are considered. For the covering abstract see IRRD 864951.
