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...

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...

Background: Bridges are one of the most critical parts a transportation network that may be damaged during earthquakes and it is necessary to have prediction model for bridge responses under seismic loads can extended other situations. Soil stiffness significantly affects load distribution when soil, piles, abutment, superstructure all act as combined system resist lateral loading on bridge. Me...
