Evaluation of surface roughness and bond-slip behavior of new textured epoxy-coated reinforcing bars
… smooth epoxy coating significantly reduces the bond between concrete and reinforcing steel, which often results in the early development of transverse cracks in bridge decks. To solve this problem, the Illinois Department of Transportation (IDOT) proposed a new type of textured epoxy-coated …

Advanced beam finite element models with warping and bond-slip for concrete structures: addressing objectivity issues, prestressing and time-dependent effects [Modelli avanzati di elementi di trave con warping e bond-slip per strutture in calcestruzzo: analisi dei problemi di oggettività, precompressione ed effetti dipendenti dal tempo]
… proposta una nuova formulazione force-based con bond-slip, nella quale l’interazione acciaio-calcestruzzo è incorporata lungo l’intera lunghezza dell’asta e la precompressione può essere applicata direttamente a livello di elemento. L’approccio consente la gestione di tracciati di cavi …

An Analytical Study on the Behavior of Reinforced Concrete Interior Beam-Column Joints
… can be used to study the flexural-shear-bond interaction, the failure modes, and sensitivity of various parameters of structural elements. Most of the existing analytical approaches for interior BC joints have either failed to account for the cyclic bond-slip behavior and the triaxial …

Finite Element Analysis and Experimental Validation of Reinforced Concrete Single-Mat Slabs Subjected to Blast Loads
… investigated the effect of using various bond-slip models in studying the behavior of these twelve RC slabs subjected to blast loading. LS-DYNA®, a non-linear transient dynamic finite element analysis program, was used in this study. Finite element models for twelve slabs using the …

Time-dependent response of flat plate structures under high sustained load
… good agreement. In order to isolate and study bond behavior under high sustained load, ASTM A944 (2004) beam-end tests were subjected to sustained load levels ranging from 71 percent and 100 percent of their ultimate capacity and observed until failure or at least 20 days. Four-specimen groups …

Numerical Simulation of Reinforced Concrete Subjected to Multiaxial Stress Conditions
… by cracking, crushing, aggregate interlock, bond slip, dowel action, shrinkage and creep. Because the reinforced concrete involves so many nonlinear phenomena interacting with one another, the formulation of a "complete" analytical model is very difficult. The focus of this study is cast on: …

Numerical modelling of time-dependent cracking and deformation of reinforced concrete structures
… is smeared through the concrete elements and bond-slip between steel and concrete is accounted for indirectly by including the tension stiffening effect. The second approach is the localized cracking approach, in which concrete fracture models are used in conjunction with bond-slip interface …

Nonlinear Finite Element Analysis of FRP Strengthened RC Beams under Static and Cyclic Loads
… finite element models also neglected the bond-slip between FRP-adhesive-concrete interfaces in FRP strengthened RC beams. Furthermore, components such as adhesive and stirrup, which may play significant roles in structural behaviour of FRP strengthened RC beam, have been neglected in most …

A generalized finite element method for three-dimensional fractures in fiber-reinforced composites
… formulation of the Embedded Reinforcement with bond Slip (mERS) that allows its combination with the GFEM where fractures are represented using enrichment functions instead of meshes fitting the crack surface. Matrix cracks are described using discontinuous and singular functions as in the GFEM …

Experimental and Theoretical Investigations of a New Flat Slab System Incorporating GFRP Stay-In-Place Structural Forms and Embedded I-Beams
… forms span the spacing between, and are bonded to, the lower flanges of the I-beams. Different components of the floor were investigated. Flexural behaviour in the direction transverse to the I-beams was investigated in the positive and negative moment regions using 2,575×610×225 mm slab …

Examination of flexural crack width prediction in concrete: comparison of analytical and numerical models
… confidence with which durability can be ensured. Bond failure between concrete and the embedded reinforcing steel exposes the steel surface within a crack path. This relative slip results from differential tensile strain between concrete and steel that allows harmful ions to reach and then react …
