RESULTS FROM HIGH AMPLITUDE DYNAMIC TESTS AND IMPLICATIONS FOR SEISMEC DESIGN

A dynamic field experiment to investigate distribution of lateral seismic loads on a 400 foot long reinforced concrete bos girder bridge, carried out in May 1982, is described. Four hydraulic rams were used to induce dynamic loads by the quick-release method. The largest release loads used during the dynamic experiments had a magnitude of one and one-half times the design earthquake loads. Preliminary results indicate that damping may be fairly low for bridges of this type, and that the soil-structure interaction phenomenon plays a very significant role in the response of this fairly typical highway bridge.
