Steel-concrete bond behavior: An experimental and numerical study

Construction and Building Materials, 2021
Abstract This manuscript aims to evaluate the steel-concrete bond behavior using experimental and numerical procedures considering pull-out tests, with a C35 concrete (strength class of 35 MPa). The experimental procedure considers steel bars with diameters of 6.3, 8.0 and 10. The numerical procedure considers steel bars with diameters of 6.3, 8, 10,

A strain-softening model for steel–concrete bond

Cement and Concrete Research, 2003
Abstract A new analytical model is proposed to describe the bond strength between a ribbed reinforcement bar and concrete. The model is based on the partly cracked solution of a thick-walled cylinder exposed to radial internal pressure. Instead of considering the minimum crack number in previous solutions, smeared cracking and average stress–strain ...

Adhesive-bonded steel/concrete composite construction

International Journal of Adhesion and Adhesives, 1982
Abstract The development of a new form of roadway deck for bridges is described. This consists of a concrete core bonded to a steel soffit plate using epoxy resin adhesive. The durability of structural joints made with a number of adhesives and with steel, concrete, and aluminium adherends is being investigated.

Artificial neural network model for steel–concrete bond prediction

Engineering Structures, 2009
Abstract In this paper, an Artificial Neural Network (ANN) is proposed for modelling the bond between conventional ribbed steel bars and concrete. The purpose is to predict the ultimate pull-out load from the concrete mix constituents (first ANN model) or the compressive strength (second ANN model) and from the steel bar diameter according to the ...

STEEL-CONCRETE COMPOSITE GIRDER WITH EPOXY BONDING.

Proceedings of the Institution of Civil Engineers, 1990
Tests on a steel-concrete composite girder with epoxy bonding instead of the usual shear connectors at the interface are described. A girder of 4.5 m effective span was subjected to 2 million cycles of pulsating load, and its behaviour was monitored periodically. The epoxy bonding did not show any signs of deterioration up to ultimate load.

Experimental study of bonded steel concrete composite structures

Journal of Constructional Steel Research, 2007
Abstract This paper deals with the experimental analysis of the mechanical behaviour of bonded steel–concrete composite structures. The steel girder and the concrete slab are assembled by adhesives. The effect of the main parameters, such as the adhesive nature and the irregular thickness of the adhesive joint, on mechanical performance and ultimate ...

A non-linear thermodynamical model for steel–concrete bonding

Computers & Structures, 2012
In Reinforced Concrete structures, the concrete damage configuration as well as the crack pattern distribution depend directly on bonding, and its implementation for numerical analysis is still complicated. In this work, a new thermodynamical non linear bond model is introduced taking into account tangential bond deterioration and coupling between ...

Steel‐Concrete Bond Analysis with Nonlocal Continuous Damage

Journal of Structural Engineering, 1991
This paper deals with the application of continuum damage mechanics to the description of the response of reinforced concrete members. Two simplifying assumptions are made: (1) The constitutive law of concrete is the isotropic damage law; and (2) there are no displacement discontinuities at the interface between steel and concrete (this last statement ...

Influence of carbon nanotubes on steel–concrete bond strength

Materials and Structures, 2018
In this study, the bond strength between steel and concrete reinforced with multi-walled carbon nanotubes (CNTs) is analysed. To this end, pull-out tests were carried out for concretes with incorporation of 0.05–0.1% of different types of functionalized and unfunctionalized CNTs with distinct aspect ratios and dispersion techniques.

Analysis of Steel-Concrete Composite Frames with Bond-Slip

Journal of Structural Engineering, 2001
Recent developments in modeling the slip in steel-concrete composite beams have led to an accurate and numerically stable force-based frame element. The element assumes force fields rather than displacement fields along the element. After a brief review of the element formulation, the paper discusses a new phenomenological law for the shear connection ...
