Seismic Response of 3-Span Bridges Considering the Effect of Failure of Bearings
Although the effect of bearings and restrainers has been considered in seismic response analysis of bridges, the effect of failure of those structural components has not yet been fully analyzed. This paper presents an analysis of a 3-span simply supported bridges that are supported by elastomeric bearings. Cable restrainers are accommodated between decks. It is shown from the analysis that bearings fail progressively from the edges due to rotations of the decks, and it is also shown that design concept to evaluate demands of the bearings and unseating prevention devices by dividing the total demand by number of devices underestimates the real demands at in particular edge girders.
