Book excerpt: ABSTRACT: The enclosed work focuses on shear strengthening of reinforced concrete beams with carbon fiber sheets. The use of composite materials is increasing in rehabilitation of concrete structural elements. The advantages over concrete are high strength to weight ratio and high resistance to corrosion over steel structures. Over time, concrete beams lose their strength due to corrosion of the reinforcement inside the beam. To replicate this condition in the field, research on concrete beams was performed and experimental tests and analytical investigations were conducted to prove the validity of the research. Several T-shape rectangular beams were tested, and they were externally reinforced with carbon fiber. The bonding of the material to the concrete surface, the surface preparation, and the orientation of the fiber were important factors in strengthening the beam in shear. Two samples were tested in as-build conditions. Four other samples were externally reinforced with carbon fabric composite sheets. By applying the carbon externally, significant improvement on the shear strength of the concrete beam was achieved. Samples were modeled in a finite element (FE) program, ABAQUS, to verify the actual conditions acting on the beam during testing. The FE results were found to be similar to the experimental findings.

Available in PDF, EPUB and Kindle. Book excerpt: Reinforcement corrosion is the most common deterioration problem observed in reinforced concrete (RC) structures located at coastal or cold regions. The corrosion process can impact the performance of these structures by inducing damage on the bonding action between concrete and steel, either by the splitting of the concrete cover due to the volumetric expansion of corrosion products or the lubricant effect at the steel/concrete interface as the corrosion by-products accumulate. The current research aims at investigating corrosion-induced deterioration of bond between steel and concrete through finite element (FE) analysis of the flexural behaviour of corroded RC components. By treating the concrete cover as a thick-wall cylinder subjected to internal pressure, the analytical evaluation of impaired bond capacity is studied first and verified against published bonding tests. Then, the formulation of a numerical model is performed using ABAQUS, wherein a link element to simulate the bond behaviour is formulated and implemented through the ABAQUS user-subroutine (UEL) feature according to the validated analytical model. By introducing corrosion-induced damages, i.e., smaller cross-sectional area of reinforcement, splitting of concrete and bond deterioration, in the FE analyses, the results of the numerical model show good agreement with experimental observations. Upon validation of the analytical and FE models, a parametric investigation is conducted, wherein the effects of concrete strength, dimension of reinforcing bars, properties of oxide products, different corrosion damage mechanisms and the corrosion location along the longitudinal reinforcement on the flexural behaviour of RC beams are studied. The results show that the analytical evaluation for bond degradation is impacted by the selection of the post-cracking material model and the thickness of cover that determine the 'holding capacity' after cracking initiation. Also, the density of rust by-products affects the results of the analytical model at high corrosion levels. From the FE model results, it was observed that each damage mechanism due to corrosion contribute to different levels of flexural degradation, although the flexural strength degradation is mainly due to the loss of bonding action. The parametric study also demonstrates that flexural members which have reinforcement corrosion initiated near the supports suffer greater deterioration in flexural capacity than those with damages at mid span. Finally, based on these observations, suggestions for the application of both analytical and numerical models are made.

This book was released on 2008 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion of reinforcing steel is a major problem facing infrastructures owners with billions of dollars spent in repairing our aging infrastructure. One of the first steps in the repair process is to quantify the strength degradation in a reinforced concrete element caused by the corrosion of reinforcing steel. An understanding of the forces involved in the load carrying mechanisms is imperative; the transfer of shear forces in reinforced concrete beams is one of these load carrying mechanisms. The shear transfer mechanism is different near the end of beams, adjacent to point loads, and near changes in cross section. These regions are known as disturbed regions. Structural engineers have a good understanding of the shear transfer mechanism in disturbed regions. However, the effects of corroded shear reinforcement in these regions have not been widely investigated. The current study is comprised of an experimental program and analytical strut and tie modeling aimed at quantifying the strength reduction that occurs in disturbed regions of reinforced concrete beams with corroded shear reinforcement. The feasibility of strengthening a beam with dry lay-up carbon fibre reinforced polymer (CFRP) to repair the damage caused by corrosion of the shear reinforcement was also investigated. In the experimental study, a total of 16 reinforced concrete beams were cast. The specimens were 350 mm deep, 125 mm wide and 1850 mm long. Three shear-span to depth ratios (1.0, 1.5, 2.0) were selected. Each specimen was reinforced in flexure with two 25M bars and the shear reinforcement was 10M spaced at 150 mm on centre. The specimens were corroded for 21 days, 60 days, and 120 days corresponding to low, medium, and high corrosion levels. In addition, three specimens were constructed without shear reinforcement in the shear-span in order to compare the results from the corroded specimens. One specimen was also corroded to a high level and repaired with dry lay-up CFRP. The specimens were corroded using an accelerated corrosion technique. There was evidence of cracking of the cover concrete in all specimens, and in the more severely corroded specimens delamination of the cover concrete was recorded. The stiffness of the corroded specimens was less than their corresponding control specimen, and a strength reduction was evident in most specimens. The maximum recorded strength reduction was 52% compared to the companion uncorroded specimen. It was revealed that a more critical case occurs when the corroded shear reinforcement was shifted during placement or was inclined closer to the direction of the compressive force flow. Also, it was observed that the corroded shear reinforcement still provides limited ductility in comparison to the un-corroded reinforcement. A strut and tie model was developed based on the experiments to explain the behaviour of disturbed regions with corroded shear reinforcement. The model consisted of direct and indirect struts. The effects of corrosion were expressed in terms of a reduction in the stirrup cross-section, a reduction of compressive strength due to corrosion cracking, and a reduction in the concrete cross section width. It was hypothesized that the corrosion crack width influences the concrete compressive strength in the strut; consequently, a mathematical model was developed that related the reduction in concrete compressive strength with corrosion crack width. Also, a relationship between reinforcing steel mass loss and corrosion crack width was utilized from the published literature. An effective cross section width was obtained by reducing the width by the damaged concrete cover. The results from these models were input into a strut and tie model as a reduction in concrete compressive strength. The output from the strut and tie model was the ultimate shear strength of the specimen. The developed models were compared with a model from the literature and compared with the experimental results. The major contribution of this research is to allow designers to analyze disturbed regions with corroded shear reinforcement and determine the strength degradation; subsequently, one can determine what strengthening procedure would be most appropriate.

Available in PDF, EPUB and Kindle. Book excerpt: This work is devoted to the study of the debonding of thin bonded cement-based overlays from the concrete substrate under mechanical loading. As repair materials, fiber-reinforced and rubbberized cement-based mortars are used. Under these conditions, assessment of durability of the repairs necessarily involves the study of the degradation of the bridging strength under fatigue loading. In this context, tensile fatigue tests controlled by crack mouth opening displacement (CMOD) are conducted on composite specimens in order to establish the degradation law of fiber-reinforced and/or rubberized mortar. The bridging strength decreases with the number of fatigue cycles for the same maximum crack width, whatever the nature of the composite. The maximum cyclic bridging strength degradation occurs in plain mortar. The cyclic bridging strength degradation for large pre-cracked widths is limited for mortar reinforced with metallic fibers. In case of rubberized mortar, cyclic bridging strength degradation is limited at less pre-cracked width values. A combine use of rubber aggregates and fibers in mortar appeared to be a suitable solution to limit the cyclic bridging strength degradation for a wide range of pre-cracked widths. It confers to the composite an interest for durable application such as cement-based thin bonded overlays. Taking into account the main cause of distress in thin bonded cement-based applications i.e. cracking and interface debonding, different surface preparation techniques were evaluated in this research. Among them, the sandblasting one is usually implemented in actual conditions. In order to investigate the structural performance, composite beams consisting of a thin repair layer on top of sandblasted substrates are subjected to three point bending tests (monotonic and fatigue). For monitoring the evolution of cracking in the repair layer and of debonding at interface, digital 3D image correlation technique is used. It emerges as a conclusion that the rubber aggregates incorporation in repair material is helpful to control micro-cracking, which results in the delay of the debonding initiation. Moreover, a fiber-reinforcement of repair material is also helpful to limit the interface debonding propagation by restraining opening of the crack. So, the dual-use of rubber aggregates and fibers in the repair material of thin bonded cement-based overlays can be a suitable solution to delay the debonding initiation and also to limit the interface debonding propagation. This shows that the synergetic effect provided by the combine use of rubber aggregates and fibers remains valid under fatigue loading also. The used rubber aggregates are obtained by grinding end-of-life tyres. In such conditions, the approach brings an added value, the recycling of this industrial by-product being also a contribution to the maintenance of a clean environment. Incidentally, this approach also helps towards the development of a circular economy.

This book was released on 2018 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an urgent need to develop economic and efficient methods to repair and strengthen existing reinforced concrete structures. This demand is motivated by several factors including the aging of concrete structures, the desire to upgrade design standards, and the exposure to severe environmental effects. A particular problem confronting engineers in repairing deteriorated structures is the rehabilitation of reinforced concrete elements. Conventionally, steel plates were utilized to restore and enhance the tensile strength of damaged concrete members. Despite the effectiveness of this practice in terms of improving the structural capacity, it is still considered disadvantageous due to the excessive weight of steel and its susceptibility to corrosion in moist environments. The application of fibre reinforced polymer (FRP) to existing reinforced concrete structures has gained the interest of many researchers in the last few decades. These materials are superior to steel when it comes to comparing the resistance to electrochemical corrosion, strength-to-weight ratio, ease of handling, fatigue resistance, and availability in any length or shape. However, there is still a serious concern regarding the effect of premature debonding of the FRP plates before reaching the desired strength or ductility. This debonding can initiate from the ends of the plate or can be induced by intermediate cracks in the concrete member. Although the end-plate debonding and peeling mechanisms have been studied extensively, there is still a significant lack of data for FRP-strengthened beams in which intermediate crack-induced debonding is the dominant failure mode. On the other hand, the interfacial bond capacity between the concrete and the FRP composite has not been thoroughly investigated. Whereas, there is still need to study the effect of some of the mechanical and physical parameters on the bond strength of FRP-Concrete interface. Moreover, researchers have also shown a keen interest in simulating flexural cracks in concrete beams, and examine their effect on the debonding mechanisms of FRP materials. However, more realistic approach is needed to model cracks and account for their growth. In this study, a three-dimensional nonlinear finite element model was developed for simulating the flexural behaviour of RC beams externally bonded with FRP systems. The ABAQUS/CAE software version 6.14-2 was used for this purpose. This numerical analysis was performed based on a comprehensive experimental program conducted by Brena et al. (2003). The simulated RC beams were categorized in two groups: Control Beams (without fibre) and CFRP Beams (with carbon fibre reinforced polymer). During the process of constructing the CFRP beam models, two distinct procedures were followed to simulate the interface between the concrete and the externally attached FRP laminates. Perfect bond was assumed in the first approach, and a Cohesive Zone Model (CZM) was adopted in the second approach. In the latter, cohesive surface technique was implemented in the ABAQUS model through the use of traction-separation law. Despite the lack of quantitative evaluation in the literature as no similar techniques was attempted by others, the results of this numerical analysis were only compared with experimental findings, and the proposed models were found to be reliable. A parametric study was performed to investigate the influence of various parameters on the flexural capacity of the proposed beam model, and the debonding behaviour of the externally attached FRP laminate. This analysis was conducted by either changing the mechanical properties of some of the constitutive materials (e.g. concrete and reinforcing steel), or altering the geometrical and mechanical properties of the FRP reinforcement. It was then found that the effect of internal steel reinforcement ratio has the most impact on beam ultimate capacity. While changing the FRP bond length beyond a certain value bears no effect on beam strength. Moreover, the numerical model was modified to review the effect of intermediate crack spacings on the overall beam performance. A discrete crack approach was adopted to replicate crack propagation throughout the body of the beam. This technique has shown an approximately 30% improvement in the prediction capacity of this model when compared to a similar specimen in which smeared crack approach is used. The results of this analysis showed that the debonding behaviour of FRP laminates is largely influenced by crack spacing. In addition, the results have also indicated that the initiation of FRP micro-debonding was prolonged as crack spacings were decreased. This response can be attributed to the abrasion effect within the FRP-Concrete interface. Finally, this numerical analysis provides a relatively reliable guidance on the application and the mitigation of externally bonded FRP reinforcement in concrete beams. The predictive capability of the proposed FE models ensures their suitableness for further investigations of FRP effectiveness in civil engineering field.
