The optimal shapes of piles in integral abutment bridges [PDF]
Journal of Traffic and Transportation Engineering (English Edition), 2017 Abstract Integral abutment bridges (IABs) can be used to avoid the durability issues associated with bearings and expansion joints. For this type of bridge, the design of the optimal pile foundation, especially with respect to the horizontal stiffness, is a challenging issue.

Study on Calculation Method of Larger Unbalanced Earth Pressure of Backfill behind Abutment in Integral Abutment Jointless Bridges [PDF]
Zhengzhou Daxue xuebao. Gongxue ban, 2022 In order to study the variation of larger unbalanced earth pressure of backfill behind abutment caused by vehicle load, several reciprocating low-cycle pseudo-static tests on interaction of soil-abutment-steel H-pile with or without considering the ...

Experimental and analytical study of integral-abutment bridges
, 2018 Integral-abutment bridges eliminate the expansion joints that are generally used to accommodate bridge length changes due to daily and annual temperature variations. Additional stresses and displacements due to the thermal loading are induced in these indeterminate structures that are not typically associated with bridge structures supported on pins ...

Frontiers in Built Environment, 2022 Expansion and contraction of integral abutment bridges due to temperature changes force integral bridge abutments (IBAs) to move toward and away from the backfill, thus increasing horizontal earth pressures behind the abutments and inducing bending ...

Effects of Geogrid Reinforcement on the Backfill of Integral Bridge Abutments
Buildings, 2023 The construction of integral bridges is one of the most effective methods to reduce bridges’ construction and in-service costs. However, there are associated geotechnical problems with their abutments backfill due to the integrated abutments.

Earthquake Resistance of Integral Abutment Bridges
, 2009 intermediate length bridges. Integral abutment construction eliminates joints and bearings which reduce long-term maintenance costs. However, in the absence of joints and bearings, the bridge abutments and foundations must be able to accommodate lateral ...

Environment-Induced Performance of End Concrete Diaphragm in Skewed Semi-Integral Bridges
Buildings, 2022 Past research has shown that as skewed bridges change temperature, additional lateral movement or forces will occur along with the elongation of the bridge. Even though past research has documented this behavior, lateral movements of semi-integral bridge

Investigation on Flooding-Resistant Performance of Integral Abutment and Jointless Bridge
Advances in Civil Engineering, 2020 Bridge washouts connected to flood events are deemed one of the main reasons for structural collapse. Compared to traditional continuous jointed bridges, integral abutment and jointless bridges (IAJBs) have better lateral stability because there are no ...
