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.

This book was released on 2001-01-01 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: In December 1996, the then CEB established a Task Group with the main objective to elaborate design guidelines for the use of FRP reinforcement in accordance with the design format of the CEB-FIP Model Code and Eurocode2. With the merger of CEB and FIP into fib in 1998, this Task Group became fib TG 9.3 FRP Reinforcement for concrete structures in Commission 9 Reinforcing and Prestressing Materials and Systems. The Task Group consists of about 60 members, representing most European universities, research institutes and industrial companies working in the field of advanced composite reinforcement for concrete structures, as well as corresponding members from Canada, Japan and USA. Meetings are held twice a year and on the research level its work is supported by the EU TMR (European Union Training and Mobility of Researchers) Network "ConFibreCrete”. The work of fib TG 9.3 is performed by five working parties (WP): Material Testing and Characterization (MT&C) Reinforced Concrete (RC) Prestressed Concrete (PC) Externally Bonded Reinforcement (EBR) Marketing and Applications (M&A) This technical report constitutes the work conducted as of to date by the EBR party. This bulletin gives detailed design guidelines on the use of FRP EBR, the practical execution and the quality control, based on the current expertise and state-of-the-art knowledge of the task group members. It is regarded as a progress report since it is not the aim of this report to cover all aspects of RC strengthening with composites. Instead, it focuses on those aspects that form the majority of the design problems. several of the topics presented are subject of ongoing research and development, and the details of some modelling approaches may be subject to future revisions. as knowledge in this field is advancing rapidly, the work of the EBR WP will continue. Inspite of this limit in scope, considerable effort has been made to present a bulletin that is today’s state-of-art in the area of strengthening of concrete structures by means of externally bonded FRP reinforcement.

Available in PDF, EPUB and Kindle. Book excerpt: Recently, fibre reinforced polymer (FRP) rebars have been extensively used in construction instead of steel rebars due to their non-corrosive nature and high tensile strength. Bond between FRP rebars and concrete is a critical design parameter that controls the performance of reinforced concrete members at serviceability and ultimate limit states. In order to prevent a bond failure, an adequate anchorage length should be provided. The anchorage length is derived using a bond stress-slip () constitutive law. The objective of this study is to investigate the effect of different parameters such as the type of fibre, the rebar surface and the confinement provided by the transverse reinforcement on the bond behaviour of FRP rebars in concrete. Based on the analysis, a generalized bond stress-slip relationship will be developed and a new design equation for the required anchorage length of FRP rebar in concrete will be derived. A database was created on the bond stress-slip behaviour of FRP rebars in concrete from the available literature up to 2009. The data was statistically analyzed to investigate the effect of the different parameters on the bond performance of FRP rebars. It was observed that an increase in the confinement provided by the transverse reinforcement increased the bond strength of FRP rebars in concrete. This signifies that the presence of transverse reinforcement affects the bond behaviour of FRP rebars in concrete and hence, it should be taken into consideration while developing design equations for FRP rebars. Type of fibre and rebar surface does not affect the bond stress, but the latter affects the slip corresponding to the peak bond stress. Based on the results, a nonlinear regression analysis was performed to develop the bond stress-slip model for splitting mode of failure and a design equation for determining the development length of the FRP rebars in concrete was derived. The proposed development length equation can save about 10%-15% of the d.

Book excerpt: The papers contained herein were presented at the Sixth International Conference on Composite Structures (ICCS/6) held at Paisley College, Scotland in September 1991. The Conference was organised and sponsored by Paisley College. It was co-sponsored by Scottish Enterprise, the National Engineering Laboratory, the US Army Research, Development and Standardisation Group-UK, Strathclyde Regional Council and Renfrew District Council. It forms a natural and ongoing progression from the highly successful ICCS/1/2/3/4 and 5 held at Paisley in 1981, 1983, 1985, 1987 and 1989 respectively. As we enter the final decade of this century many organisations throughout the world are adopting a prophetic role by attempting to forecast future scientific advances and their associated impact on mankind. Although some would argue that to do so is folly, without such futuristic visionaries the world would be that much poorer. IntelJigent speculation based on research trends and historical advances, rather than fanciful theories, breathes a healthy air of enthusiasm into the scientific community. Surely this is the very oxygen necessary to ignite the fir~s of innovation and invention amongst pioneers of research.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Glass fiber reinforced polymer (GFRP) bars are emerging as concrete reinforcements especially in applications where corrosion resistance properties are required. This dissertation focuses on bond properties, microstructure and post-fire behavior of GFRP bars. First, the bond of three GFRP bars with different surface characteristics was investigated by performing pull-out tests. A parametric bond-slip relationship was proposed for the GFRP bar with sand coated surface. The parameters were found by performing sensitivity analysis. The proposed bond-slip law was employed in an FEM model to predict the failure mode. Additionally, the model was employed in a GFRP-RC slab to replace the unrealistic perfect-bond assumption and led to more accurate results. Next, the microstructural patterns of four different GFRP bars were investigated using SEM analysis. Each bar demonstrated a unique defect/void pattern due to experiencing different manufacturing process. In order to investigate the effect of microstructure on GFRP durability, two of the bars were exposed to accelerated conditioning in an alkaline solution. The difference in microstructural patterns significantly affected the GFRP durability-related properties. Finally, the post-fire behavior of two different GFRP bars was investigated. GFRP-RC slabs were exposed to standard fire tests while being loaded at the service load. After the cooling phase, the GFRP bars were extracted for investigation of their residual mechanical properties. GFRP bars maintained the mechanical properties and no microstructural degradation was observed. Additionally, a thermomechanical model was developed to predict the temperature distribution and investigate the effect of the fire on the structural response and concrete cracking.
