Development of Preflex Composite Beam-Stub Abutment Intergal Bridge System

Abstract

In this paper, we present the results of an analytical study pertaining to the structural behavior of pre-deflected (so-calledpreflex) beam-stub abutment integral bridge system. In this bridge system, pre-deflected composite beam is conected withstub-type abutment resting on the H-piles driven in a row in the perpendicular direction of bridge span. To investigate thelength of bridge and the height of abutment. The results of an analytical study on the preflex composite beam-stub abutmentintegral bridge system were compared with those of the conventional joint bridge system, and the design of preflex compositebeam, stub abutment, and pile foundation is also briefly discussed.
