END‐Bearing Piles in Jointless Bridges
Journal of Structural Engineering, 1988An algorithm based on a nonlinear finite element procedure previously developed by the writers is modified and used to study the effect of thermally induced lateral movement on the vertical loadcar...

Abutment Pile Design for Jointless Bridges
Journal of Structural Engineering, 1989Abutment piles for a jointless bridge are subjected to lateral displacement as the bridge superstructure expands and contracts. The piles must be designed to satisfy the strength criteria of a structural member and the load transfer requirements and support resistance of the surrounding soil. Two design alternatives for the pile capacity are presented.

In-Service Performance of Integral Bridges and Jointless Decks
Transportation Research Record: Journal of the Transportation Research Board, 1998New York has been building integral bridges as well as jointless decks since the late 1970s. They performed well from the beginning, but a recent study evaluated their performance to identify details possibly needing improvement in future construction.

Engineering Journal, 1987
Todays bridge designer is striving essentially to achieve the same goals as his counterparts were 50 years ago: long term serviceability, low maintenance characteristics and economy of construction. While we have mastered new techniques such as welding, composite decks, hybrid girders, load factor and autostress designs, we still cling to many of the ...

Partial Continuity in Bridge Girders with Jointless Decks
Practice Periodical on Structural Design and Construction, 2005Many bridges are constructed in groups of simple spans. This construction system requires the use of deck (expansion) joints over piers, leading to numerous problems that are costly to maintain or repair. The use of jointless bridge decks is one of the alternatives gaining popularity among bridge engineers and officials. The construction of new bridges

Continuity Considerations in Prestressed Concrete Jointless Bridges
Structures 2004, 2004Jointless bridges, which have been constructed by several states, promote reduced maintenance costs, improved riding quality, lower impact loads, reduced snowplow damage to decks and approaches, and improved seismic resistance. In spite of many of these recognized benefits, the behavior of such structures is not yet fully understood, and nationally ...

Buckling of piles in cohesive soil supporting jointless bridges
Bridge Structures, 2012Soil-structure and especially soil-pile interaction is one of the main sources of complication in the analysis of jointless bridges. Because of the complexity of the problem, calculation of the critical buckling load of embedded piles has always been a concern to the designers since piles are relatively slender elements.

Jointless Concrete Bridges – Development of a Flexible Abutment
IABSE Reports, 2007<p>For bigger concrete bridges the jointless construction hasn’t been established up to now. Concerns regarding the durability still exist since constraint stresses as a result of temperature alterations and shrinkage lead to crack initiation. With the use of the new flexible abutment these restraint stresses and occurring cracks can be reduced ...

Mobilization of Passive Earth Pressures Behind Abutments of Jointless Bridges
Transportation Research Record: Journal of the Transportation Research Board, 2004Bridges without expansion joints are referred to as integral bridges. The abutment and the superstructure of integral bridges act as a single structural unit. As the temperature of an integral bridge changes, the length of the bridge increases and decreases. The changes push the abutment against the approach fill and pull it away and thus cause lateral
