Towards this objective, a numerical example is considered in which, the thermal loading parameter and the soil parameter are varied. The multi linear spring stiffness of soil at abutment-backfill interface and at soil pile interface considered in the study are computed and adopted for the soil-structure interaction studies. The response of Integral Abutment Bridges (IAB) is studied, principally in terms of the displacements and bending moments in the superstructure deck. The study revealed that the response of the IAB is very sensitive to the thermal loading especially at larger temperature change. The effect of rise in temperature significantly affects the behavior of deck only adjacent to the abutments. However, elsewhere the effect is negligible. The influence of type of soil as backfill and around piles on the behavior of the deck girder is not significant. September - November 2014 Copyright © 2014 i-manager publications.
