Seismic response control of integral abutment bridge using sleeved piles

Abstract

Integral abutment bridges IAB are constructed without any deck joints with abutment and pier In a single span construction the deck is cast integrally with abutment In the case of a multi span construction the intermediate support to the deck is provided either by flexible pier with deck integrated monolithically with the pier or by rigid pier with a bearing on it supporting the deck This practice is a significant deviation from the conventional method of bridge construction which employs
