Book Description
The goal of this thesis was to investigate the behavior of short and slender concrete columns internally and externally reinforced with longitudinal fiber-reinforced polymer (FRP) composites. The study was divided into two major parts. First part addressed the issues regarding the use of FRP as internal reinforcement for new constructions and the second part focused on external FRP reinforcement for strengthening of existing concrete columns. There is a lack of knowledge and experimental data on the use of longitudinal FRPs as external and internal reinforcement. The contribution of FRP bars in compression is ignored by many design guidelines and the use of longitudinally bonded FRPs in compression is not suggested by guidelines due to lack of experimental test data. There is also lack of knowledge regarding the effect of slenderness and associated parameters (e.g., critical slenderness ratio and flexural stiffness) for the columns. Also, the effectiveness of confinement for eccentrically loaded concrete columns is not well-known. Therefore, this thesis addressed the issues regarding the use of external and internal FRP reinforcement in concrete columns using experimental, analytical, numerical, and statistical approaches. To characterize the compressive behavior of FRP bars as internal reinforcement, three different experimental programs were conducted to include a total of 24 columns, including 10 large-scale and 14 small-scale tests, and 35 compressive FRP bar coupons, in part I of the study. In part II, the use of FRPs as external reinforcement were experimentally assessed by testing a total of 36 column in four different experimental programs, including 6 large-scale tests and 30 small-scale tests. For further investigation, a model was developed in MATLAB for second order analysis of concrete columns reinforced internally or externally with FRPs using one-dimensional finite difference method. The nonlinearity of material and geometry and the effect of eccentricity in confinement were also considered. After required verifications, the model was used to perform a parametric study for different parts of the study and to include 18432 different cases. The model was used for a preliminary reliability-based analysis including 800,000 second-order analysis to assess the reliability corresponding different critical slenderness ratios.

Book Description
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.

Book Description
Concrete Composite Columns: Behavior and Design focuses on confined concrete and establishes analytical methods for each composite column. The volume moves beyond existing resources to study the relationship between existing composite structures and design methods for the sectional form of a concrete composite structure. Chapters cover the failure criteria of concrete, confined concrete types, models, including axial stress prediction, analysis and design-oriented constitutive models, the design and analysis of section form, axial and seismic behaviors of concrete composite columns, the seismic design of concrete composite columns, and the engineering application. This book offers a practical solution to students, researchers, and engineers working with both steel and FRP-confined concrete composite columns. Focuses on confined concrete and provides analytical methods for composite columns Discusses different types of composite columns, including FRP and steel-concrete composites Considers the construction method and confining forces in composite concrete columns Details confined concrete from basic theoretical analysis to seismic behaviors and design methods Provides a solution to students, researchers, and engineers working with confined composite columns

Book Description
The Concrete Solutions series of International Conferences on Concrete Repair began in 2003 with a conference held in St. Malo, France in association with INSA Rennes. Subsequent conferences have seen us partnering with the University of Padua in 2009 and with TU Dresden in 2011. This conference is being held for the first time in the UK, in association with Queen’s University Belfast and brings together delegates from 36 countries to discuss the latest advances and technologies in concrete repair. Earlier conferences were dominated by electrochemical repair, but there has been an interesting shift to more unusual methods, such as bacterial repair of concrete plus an increased focus on service life design aspects and modelling, with debate and discussion on the best techniques and the validity of existing methods. Repair of heritage structures is also growing in importance and a number of the papers have focused on the importance of getting this right, so that we may preserve our rich cultural heritage of historic structures. This book is an essential reference work for those working in the concrete repair field, from Engineers to Architects and from Students to Clients.

Book Description
The first textbook on the design of FRP for structural engineering applications Composites for Construction is a one-of-a-kind guide to understanding fiber-reinforced polymers (FRP) and designing and retrofitting structures with FRP. Written and organized like traditional textbooks on steel, concrete, and wood design, it demystifies FRP composites and demonstrates how both new and retrofit construction projects can especially benefit from these materials, such as offshore and waterfront structures, bridges, parking garages, cooling towers, and industrial buildings. The code-based design guidelines featured in this book allow for demonstrated applications to immediately be implemented in the real world. Covered codes and design guidelines include ACI 440, ASCE Structural Plastics Design Manual, EUROCOMP Design Code, AASHTO Specifications, and manufacturer-published design guides. Procedures are provided to the structural designer on how to use this combination of code-like documents to design with FRP profiles. In four convenient sections, Composites for Construction covers: * An introduction to FRP applications, products and properties, and to the methods of obtaining the characteristic properties of FRP materials for use in structural design * The design of concrete structural members reinforced with FRP reinforcing bars * Design of FRP strengthening systems such as strips, sheets, and fabrics for upgrading the strength and ductility of reinforced concrete structural members * The design of trusses and frames made entirely of FRP structural profiles produced by the pultrusion process
