Abstract
This paper proposes an evaluation method of stress vs. strain relation of a rubber shock absorber for a seismic countermeasure of bridges. Compression behavior of the absorber subjected to an extremely high compression, induced by poundings between adjacent bridge decks, was studied. A high compression loading test was conducted with a strain as large as 70% was conducted. Finite element analysis with the Mooney-Rivlin stress vs. strain relation was conducted, and based on the results, an evaluation method for stress vs. strain relation was proposed. It was found from the comparison with the test data the proposed method predicts the stress vs. strain relation of the rubber shock absorber with acceptable accuracy.
