Abstract
Applications of fiber-reinforced polymers poles were increased in the last few years because of their high strength-to-weight ratios, high corrosion resistance, can be customized to meet strength and deflection requirements and have a low life-cycle cost of construction and maintenance. This research presents a comprehensive review of all significant research and existing case studies to review the present knowledge concerning FRP poles.
It is well-known that the design of GFRP poles is controlled mainly by serviceability requirements. Values of the flexural modulus “E” and the shear modulus “G” are considered the basic requirements for deflection calculations. Values of “E” and “G” given by the manufacturers of poles are generally conservative; that is why the previous research work done in this field tends to determine the values of “E” and “G” experimentally rather than using the manufacturer’s values.
The main goal of this study is to investigate the stiffness characteristics of the GFRP poles locally manufactured in Egypt using centrifugal casting production method with and without opening openings. Three different fixation methods were used in this study to reduce the deformations of the GFRP poles. An experimental and mathematical investigation was done on five full scale poles, parts of the poles and coupons specimens cut and tested according to ASTM standards. Values of flexural modulus “E” and shear modulus “G” were determined from all the carried-out tests. Ratio of shear deformation as a percentage from the total deformation was determined to figure out when it can be ignored without a significant error in the design purposes. Effect of the presence of opening openings in GFRP poles on stiffness characteristics was also considered.
