Title of Document: EFFECTS OF WINGWALL CONFIGURATIONS ON THE BEHAVIOR OF INTEGRAL ABUTMENT BRIDGES Andreas Paraschos, Doctor of Philosophy, 2016 Dissertation Directed By: Professor Amde M. Amde Department of Civil and Environmental Engineering This research includes parametric studies performed with the use of three-dimensional nonlinear finite element models in order to investigate the effects...

Integral Abutment Bridges (IAB) are defined as simple or multiple span bridges in which the bridge deck is cast monolithically with the abutment walls. This kind of bridges are becoming very popular due to different aspects such as good response under seismic loading, low initial costs, elimination of bearings, and less maintenance. However the main issue related to the analysis of this type of...

To establish a maximum safe length and design details for zero skew steel and concrete bridges with integral abutments, a survey of the highway departments of all 50 states was conducted. The findings of the survey include maximum lengths of integral abutment bridges being constructed, advantages and disadvantages of these bridges as perceived by the various states, and the extent of field obse...

 Integral bridges are gaining increased popularity because of both economic and fast construction associated with the omission of bearing supports and expansion joints. In the present study the cyclic earth pressure behind integral bridge abutments under traffic surcharges are investigated and compared with that induced behind the abutment of  conventional bridges (with isolated deck and abutme...

One of the most commonly discussed problems regarding bridges with integral abutments is the influence of longitudinal elongation of the superstructure as a result of seasonal temperature variations. A bridge built with integral abutments is often supported by a row of piles made of steel or concrete. The longitudinal elongation of the superstructure induces a displacement and a rotation at the...

Abstract The jointless bridges includes integral bridges, semi-integral and extended deck bridges. adopts an abutment, its main girder, abutment pile under are fixed together to bear the force together. expansion joint device cancelled, integrity, durability driving comfort of bridge improved. In this paper, a simply supported girder in Fujian Province China is taken as research background, it ...
