He analyzed the effects of expansion and contrac­ tion of the jointless deck and consid­ ered the interactive forces between the girders and the deck. Although the

Criteria and guidance for the design of integral bridges ...

2015-11-20  Due to the absence of aforementioned mechanisms to release structural stresses, secondary effects such as creep, shrinkage and thermal gradient have a significant influence on the behaviour of integral bridges. Several models for creep, shrinkage and thermal effects are presented and discussed in the report.

Integral Abutment Bridges or the Concept of Jointless

2017-5-12  Due to the elimination of the bridge deck expansion joints, construction and maintenance costs are reduced.. The integral abutment bridge concept is based on the hypothesis that due to the flexibility of the piling, thermal (or seismic) stresses are transferred to the substructure by way of a rigid connection between the superstructure and substructure.

Partial Continuity in Bridge Girders with Jointless

The use of jointless bridge decks is one of the alternatives gaining popularity among bridge engineers and officials. The construction of new bridges without expansion joints, or the elimination of expansion joints in existing bridges, reduces a great portion of the direct and indirect costs associated with the use of expansion joints.
