Safety Identifying of Integral Abutment Bridges under Seismic and Thermal Loads
Integral abutment bridges (IABs) have many advantages over conventional bridges in terms of strength and maintenance cost. Due to the integrity of these structures uniform thermal and seismic loads are known important ones on the structure performance. Although all bridge design codes consider temperature and earthquake loads separately in their load combinations for conventional bridges, the t...
متن کاملEarth Pressure behind an Integral Bridge Abutment and Comparison with that behind a Conventional Bridge Abutment under Traffic Loads
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...
متن کاملPerformance Evaluation of Integral Abutment Bridges
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...
متن کاملModelling of Soil Structure Interaction of Integral Abutment Bridges
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...
متن کاملDesign Considerations for Integral Abutment/ Jointless Bridges in the USA
This paper summarizes results of a major study on jointless bridges sponsored by the U.S. Federal Highway Administration. This study included extensive laboratory and field experiments as well as detailed analytical studies. A set of design recommendations were provided. Jointless bridges have reduced maintenance, improved riding quality, lower impact loads, reduced snowplow damage, and structu...
