Article
Full-text available
This paper presents different strengthening techniques to improve the shear capacity of existing thick concrete slab structures that were constructed without shear reinforcement. Reinforcing bars are installed into vertical drilled holes and anchored with epoxy adhesive to increase the shear capacity. Experiments on retrofitted beams, representing...
Article
This paper examines the behaviour of thick concrete members strengthened in shear with unbonded transverse reinforcement. The retrofitting technique consists of placing unbonded vertical bars with steel end plates or torque controlled expansion end anchorages in pre-drilled holes of existing thick members. To study the behaviour of these members, l...
Article
Alkali-silica reaction (ASR) is one of the most damaging mechanisms affecting concrete structures worldwide. ASR effects on the durability and serviceability of damaged concrete are widely known and fairly well understood. However, the structural implications are still unclear, and a number of contradictory data are found in the literature, especia...
Thesis
Full-text available
Shear behavior of reinforced concrete structures has been studied for more than one century. Even if shear behavior is now better understood, a unique shear theory has not been commonly accepted yet. The study presented in this thesis shows that current theories cannot adequately predict the shear behavior of strengthened structures with post-insta...
Article
This paper presents experimental testing on glulam beam–column moment-resisting connections using glued-in rods (GiRod) and compares the results with model predictions. Three connection geometries and varying numbers of rods and member size were tested and compared. This experiment will be helpful in grounding research by bringing in new experiment...
Article
Full-text available
The reuse of industrial wastes to produce concrete and mortar is an environmental solution for their disposal as well as for the development of ecological and sustainable concrete. A large number of previous studies summarized in this review paper focused on adding different types of waste in the concrete and mortar mix in the form of fine aggregat...
Conference Paper
Full-text available
Due to design using older codes, material degradation and increased traffic loads, numerous reinforced concrete bridge members, such as beams and slabs, have insufficient shear capacity and need shear strengthening. An efficient shear strengthening technique consists of adding drilled-in vertical reinforcing bars within the existing concrete member...
Article
Post-installed epoxy-bonded shear reinforcement is a promising technique to increase shear capacity of reinforced concrete (RC) structures. However, the behavior of epoxy-bonded bars largely affects the shear strengthening efficiency. To better predict the behavior of epoxy-bonded bars, a bond model is developed in this paper. This model appears to...
Conference Paper
Full-text available
In order to investigate the effect of the service shear load at the time of strengthening a thick slab using bonded transverse reinforcing bars, an experimental study has been carried out. Five (5) beams representing slices of a thick slab were tested to induce different shear load levels in the beams at the time of strengthening then loaded up to...
Conference Paper
Full-text available
Efficient shear strengthening techniques for thick concrete slabs were studied at University Laval during the last decade. The strengthening techniques consist to add into the structure vertical reinforcing bars and to anchor the bars with bolted plates or torqued controlled anchorage at the bars extremities (i.e. the bars are unbonded to the concr...

Conference Paper
Full-text available
One commonly used method to increase the shear capacity of existing concrete structures consists of adding vertical steel bars anchored to the structure by means of mechanical anchorages, such as expansion torque controlled anchorages or steel anchorage plates. If the drilled holes are not filled with adhesive then the bars are unbonded along their...
Conference Paper
Full-text available
Installation of drilled-in epoxy bonded reinforcing bars is generally an effective strengthening method for deficient concrete structures. However, this method of rehabilitation has largely been studied and tested on sound concrete elements, i.e. without any pathological damage, which raises the question of bond capabilities in existing damaged ele...
Conference Paper
Full-text available
L’installation d’ancrages époxydiques à l’aide d’armatures conventionnelles constitue une méthode généralement efficace de renforcement d’infrastructures en béton armé. Toutefois, cette méthode de réhabilitation a été étudiée, puis testée sur des éléments de béton sain, c’est-à-dire sans endommagement pathologique. Le projet de recherche étudie don...
Conference Paper
Full-text available
In order to evaluate the performance of drilled-in bonded shear reinforcement, two series of large-scale slabs were tested before and after shear strengthening. Experimental results indicate that the 2006 Canadian Standard and the 2010 fib Model Code provisions overestimate the shear strength of such strengthened slabs by about 29% if the drilled-i...
Conference Paper
Full-text available
In order to study means of improving the behaviour of thick slabs without shear reinforcement a series of large-scale beams representing thick slabs was constructed and tested. Companion specimens were strengthened using drilled-in reinforcing bars to study the effectiveness of this repair technique. The behaviour of these beams, before and after s...
Conference Paper
Full-text available
Plusieurs phénomènes de dégradations des ouvrages en béton armé sont la cause de déficiences structurales. Les ponts de types dalle épaisse sans armatures de cisaillement sont particulièrement sensibles à la dégradation du béton car ce matériau est le seul pouvant résister aux efforts de cisaillement. Cette recherche porte donc sur l’effet de l’end...
Conference Paper
Full-text available
Many concrete bridges may be associated to a simple thick slabs structural system. With the increase in traffic loads and material degradation, some of these structures need to be strengthened in shear. The goal of this research is to study the behaviour of slabs strengthened with post-installed shear reinforcement and to provide an analytical meth...
Conference Paper
Full-text available
Le système structural de plusieurs ponts peut être associé à dalle épaisse en béton armé. Avec l’augmentation des charges routières ainsi que la dégradation des matériaux, certains de ces ouvrages doivent maintenant être renforcés en cisaillement. Le but de ce projet est d’étudier le comportement des dalles épaisses renforcées par divers types de r...
