DYNAMIC TEST ON MODEL BRIDGE DECK

This article describes some of the findings of report D123/RP6 published by ORE, Utrecht. A model bridge deck with a span of 3.6 M was subjected to tests designed to check whether ultimate strength would be affected by the cracks expected to develop during service. After approximately 200000 load cycles, measurements were made of maximum deflection, strain in upper and lower edges of the girders and the upper surface of the concrete. Based on the measured material characteristics, calculation using plastic theory or elastoplastic theory gave lower predictions of failure moment. Effects of cracking under repeated service loading tended to stabilise.
