Abstract
Both static and dynamic tests were carried out on an old reinforced concrete bridge prior to its demolition. The purpose of the static test was to calibrate the mathematical model used in the structural analysis. By comparing deflections, the restraining moments at the supports were estimated. This revised mathematical model was used to calculate the natural frequencies of the bridge deck and the results compared reasonably well with the measured frequencies from the dynamic tests. The study demonstrates the importance of making appropriate assumptions about the boundary conditions in an analysis. Whether these assumed conditions are realized in the prototype is a major factor affecting the accuracy of the predicted behavior of the bridge deck.
