This book was released on 2006 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this thesis is to quantify the bond & slip behavior of deformed fiber reinforced polymer rods made of carbon (CFRP) & glass (GFRP) with concrete using the data from a set of experiments conducted previously. These experiments involved a modified form of the standard pullout tests with the goal to minimize the confining action due to the surrounding concrete being in compression. This is shown by performing a finite element simulation of the experimental setup. Then a numerical study is performed to compare the experimental results with some of the bond parameter given in ACI 440.3R-04. This is followed by analytical modeling of bond slip law of GFRP which involves rigorous computational analysis and finding the unknown parameters of the adopted m-BEP model so as to predict the applied pullout force and its consequent loaded end slip to compare with the experimental data.

This book was released on 2012-06 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The differences in mechanical and bond properties of Fiber Reinforced Polymers (FRP) bars when compared to those of traditional steel reinforcement for reinforced concrete (RC) structures may affect the cracking and deformability behaviour of FRP RC members. This study investigates the bond behaviour between FRP reinforcement and concrete through experimental and numerical analysis. Experimental results on pull-out tests and direct tension tests are presented and discussed. A general procedure, derived from a cracking analysis based on slip and bond stresses, is used to study the deformability of FRP RC elements under tension. The tension stiffening effect is included via experimental nonlinear bond-slip law obtained from a laboratory pull-out test. The comparison between experimental data and numerical predictions of the reinforcement strain profile along the reinforcing bar during a tensile test confirms that the bond-based model adequately reproduces the redistribution of stresses after crack formation. Because the numerical model is flexible enough to include any "user-defined" bond-slip law and variable materials' properties, a parametric study is conducted.

Available in PDF, EPUB and Kindle. Book excerpt: Composites materials have aroused a great interest over the last few decades. Several applications of fibrous composites, functionally graded materials, laminated composites, nano-structured reinforcements, morphing structures, can be found in many engineering fields, such as aerospace, mechanical, naval and civil engineering. The necessity of lightweight structures, smart and adaptive systems, high-level strength, have led both the academic research and the manufacturing development to a recurring employment of these materials. Many journal papers and technical notes have been published extensively over the last seventy years in international scientific journals of different engineering fields. For this reason, the establishment of this second edition of Mechanics of Composites International Conference has appeared appropriate to continue what has been begun during the first edition occurred in 2014 at Stony Brook University (USA). MECHCOMP wants to be an occasion for many researchers from each part of the globe to meet and discuss about the recent advancements regarding the use of composite structures. As a proof of this event, which has taken place in Porto (Portugal), selected plenary and key-note lectures have been collected in the present book.

This book was released on 2020 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bond of reinforcement has a major influence on the behavior of reinforced concrete (RC) structures. Even though bond has been extensively studied over the past decades, there are still a number of knowledge gaps requiring investigation. This dissertation presents three studies related to the basic bond behavior of reinforcement and the influence of bond-slip on the seismic response of RC columns. The first investigation characterizes the bond behavior of iron-based shape-memory alloy (Fe-SMA) bars. Fe-SMA reinforcement provides new opportunities for design and strengthening of concrete structures thanks to their shape memory effect. However, there is currently little data on its bond performance. Experiments were conducted to study the bond-slip behavior of ribbed Fe-SMA bars embedded in concrete specimens with different levels of passive confinement. Fe-SMA bars presented a similar bond performance as conventional reinforcement, but their bond strength was reduced with heat activation in low-confined specimens. An analytical model is also proposed to calculate the transfer length of Fe-SMA bars in prestressing applications. The second investigation proposes nonlinear finite element models to accurately simulate the cyclic response of RC columns, including the effect of bond-slip. Concrete is modeled using a triaxial constitutive model recently proposed in the literature. A commonly used uniaxial steel model is modified to account for low-cycle fatigue rupture using a phenomenological criterion. The bond-slip behavior of bars is modeled using a zero-thickness interface element and a bond stress-slip law that predicts bond deterioration caused by generalized slip demands, tensile yielding of steel, and concrete damage. The proposed models accurately predict the cyclic response and failure of previously tested column components. The third investigation focuses on the effects of strain penetration and bond modification on the lateral response of RC columns. Two large-scale column specimens were tested under cyclic loading. One specimen had conventional reinforcement details, while the other had headed bars that were partially debonded along the footing to alleviate strain concentrations. Both specimens formed plastic hinges and failed due to rupture of longitudinal bars. The specimen with partial debonding presented less damage and a larger deformation capacity. Experimental data indicated that the debonding strategy reduced peak tensile strains, and increased bar slip and fixed-end rotations. However, it also reduced the lateral load resistance of the column. Companion finite element analyses have indicated that the reduction in peak lateral strength is caused by lower steel stress demands when concrete cover fails

This book was released on 2022-05-22 with total page 1500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational Modelling of Concrete and Concrete Structures contains the contributions to the EURO-C 2022 conference (Vienna, Austria, 23-26 May 2022). The papers review and discuss research advancements and assess the applicability and robustness of methods and models for the analysis and design of concrete, fibre-reinforced and prestressed concrete structures, as well as masonry structures. Recent developments include methods of machine learning, novel discretisation methods, probabilistic models, and consideration of a growing number of micro-structural aspects in multi-scale and multi-physics settings. In addition, trends towards the material scale with new fibres and 3D printable concretes, and life-cycle oriented models for ageing and durability of existing and new concrete infrastructure are clearly visible. Overall computational robustness of numerical predictions and mathematical rigour have further increased, accompanied by careful model validation based on respective experimental programmes. The book will serve as an important reference for both academics and professionals, stimulating new research directions in the field of computational modelling of concrete and its application to the analysis of concrete structures. EURO-C 2022 is the eighth edition of the EURO-C conference series after Innsbruck 1994, Bad Gastein 1998, St. Johann im Pongau 2003, Mayrhofen 2006, Schladming 2010, St. Anton am Arlberg 2014, and Bad Hofgastein 2018.
