Observing the invisible: X‐ray CT for plant–microbe interactions
New Phytologist, Volume 251, Issue 3, Page 959-966, August 2026.Utility of X‐ray computed tomography (X‐ray CT) for visualising belowground plant interactions between multiple spatial scales and focal planes. Summary Plant–microbe interactions are inherently spatial, yet the physical structure of the soil and rhizosphere is rarely treated as a mechanistic variable in experimental design.

Evaluation on the behavior of abutment–pile connection in integral abutment bridge
Journal of Constructional Steel Research, 2011Abstract Integral abutment bridges can reduce the amount and cost of construction and maintenance work since they do not have expansion joints and shoes in order to increase stability and durability of the bridges’ system. Integral abutment bridges normally have single-row H-pile systems to resist the behaviors under service loading conditions such ...

Parametric and pushover analyses on integral abutment bridge
Engineering Structures, 2011Abstract Integral abutment bridges (IABs) are jointless bridges where the girder or the deck is continuous and monolithically connected to the abutments. A usual and important problem in the design of IABs is how to deal with the soil–structure interaction behind the abutments and next to the foundation piles: this can be considered as a fundamental ...

Rigidity of abutments in integral abutment bridges
Structure and Infrastructure Engineering, 2011In this article, we present the results from a numerical and an experimental analysis of the Scotch Road integral abutment bridge located in Trenton, New Jersey. A three-dimensional, non-linear finite element (FE) model of the bridge has been developed to study the effect of thermal loading on pile–soil interaction.

Semi Static Loads in an Integral Abutment Bridge
IABSE Reports, 2016<p>In order to solve the durability problem of expansion joints and bearings, Integral Abutment Bridges (IAB) have become more and more popular. Soil Structure Interaction (SSI) is a factor that conditions the possibility of the construction of a new IAB, or the retrofitting of an existing from a simply supported bridge into an IAB. Under imposed

Field Monitoring of Integral Abutment Bridge in Massachusetts
Transportation Research Record: Journal of the Transportation Research Board, 2004Integral abutment bridges are increasingly being used to eliminate undesirable bridge joint effects on the long-term performance of bridges. Although many states use this type of construction, common design guidelines are lacking, and nonuniform limitations on integral abutment design are imposed by different agencies. Data from the field monitoring of

Integral Abutment Bridge Behavior: Parametric Analysis of a Massachusetts Bridge
Journal of Bridge Engineering, 2007Integral abutment bridges are often a preferred bridge type for moderate spans throughout the United States. However, design methods and construction details vary from state to state. Variations between states are noted in the methods employed to accommodate deformations in the piles. The significance of these differences was evaluated through a finite-

Nonlinear Analysis of Integral Abutment Bridges
Journal of Structural Engineering, 1986A state-of-the-art, three-dimensional, nonlinear finite element algorithm is developed and used to study piling stresses and pile-soil interaction in integral abutment bridges. The finite element idealization consists of beam-column elements with geometric and material nonlinearities for the pile, and nonlinear springs for the soil.
