DOWNLOAD EBOOKThe use of fibre reinforced polymers, FRP, in new structures is still limited to few demonstration projects. Innovative hybrid systems such as the concrete-filled FRP tubes are effective in facing the great demand for piling, poles, highway overhead sign structures and bridge components. The new products have to withstand aggressive corrosive environments such as the splash zone in case of marine piles. The concrete-filled glass fibre reinforced polymer, GFRP; cylindrical tube system utilizes the best characteristics of the individual materials. The FRP tube provides lightweight permanent formwork as well as non-corrosive reinforcement for the concrete, which simplify construction and reduce erection time. The round tube also confines the concrete in compression and increases its strength and ductility, while the concrete core supports the tube and prevents premature local buckling failure. Research work related to the flexural behaviour of concrete-filled FRP tubes and their behaviour under axial compression loading conditions is, however, very limited to date. A two-phase experimental program was conducted at the University of Manitoba to examine the flexural behaviour of concrete-filled GFRP tubes and their behaviour under axial compression loads as short columns. Phase-I included eighteen simple beam tests conducted under four-point bending. The beams ranged from 1.07 to 10.4 meters in span and from 89 to 942 mm in diameter. The specimens included hollow and concrete-filled GFRP and steel tubes. Different cross-section configurations including totally and partially-filled GFRP tubes with central voids were considered. GFRP tubes of different laminate structures including filament-wound and pultruded tubes were included. Also GFRP tubes with different diameter-to-thickness ratios were also considered. Phase-II included twelve stub tests under axial compression. The stubs ranged from 100 to 219 mm in diameter. Different cross-section configurations including total.

Design methodology presented in this specification allows CFFTs to be designed as flexural members, axial compression members, or members subjected to combined flexural and axial compression, in addition to shear. CFFT bridge components may include beams, arches, columns, and piles."--P. 1-1.

DOWNLOAD EBOOKRecent field applications and research findings have demonstrated the effectiveness of concrete-filled fiber reinforced polymer (FRP) tubes (CFFT) as an efficient and promising hybrid system for designing main components such as pier columns, girders and piles for a bridge system. The vision was to provide a cost-competitive unified system composed of FRP/concrete hybrid members, which may act as a viable alternative to conventional reinforced and prestressed concrete structural systems. To achieve their broad-based implementation in civil infrastructure, understanding of their behavior and developing analytical tools under full spectrum of primary and secondary load demands are essential. Response characterizations under primary load demands namely, axial compression, flexural and axial-flexural, and seismic loadings have already been reported. However, investigations under primary shear and secondary fatigue load demands remain to be addressed. The present study consists of two phases. In the first phase, an experimental and analytical investigation was undertaken to characterize the behavior of a CFFT beam. Study on shear was primarily focused on the deep beam behavior. Comparisons of behavior of deep, short and slender beams were also highlighted. A strut-and-tie model approach, pertinent to analysis of deep reinforced and prestressed concrete members, was proposed to predict the shear strength of deep CFFT beams. Prediction showed good agreement with test results. It was concluded that shear failure mode is only critical for beams with shear span less than their depth. In the second phase, a detailed study on flexural fatigue behavior and modeling was undertaken. The main objective was to evaluate the performance of beams under four basic criteria; i) damage accumulation ii) stiffness degradation, iii) number of cycles to failure, and iv) reserve bending strength. Effects of laminate fiber architecture, reinforcement index, load range, and end restraint on the.
