Utility poles are a critical component of modern infrastructure, providing essential support for power lines, telecommunications, and other utilities that are integral to everyday life. To optimize the performance of these structures and extend their service life, this study investigates a novel hybrid configuration designed to enhance durability and efficiency. The proposed design consists of three distinct layers: fiber-reinforced polymers tapered shell, lightweight-aerated concrete, and steel tubing. Comprehensive experimental testing of full-scale utility poles was conducted. The Digital Image Correlation (DIC) method was employed to measure deflections and strains across the hybrid poles. Two specific densities of lightweight-aerated concrete were examined: 1200 kg/m3 and 1400 kg/m3. A total of four full-scale utility poles were tested following ANSI standard for utility poles. The failure occurred at the fixed end as expected, and it was observed that the higher-density aerated concrete significantly enhanced the poles’ flexural behavior and reduced tip deflection by 20% compared to the lower-density.

摘要

Utility poles are a critical component of modern infrastructure, providing essential support for power lines, telecommunications, and other utilities that are integral to everyday life. To optimize the performance of these structures and extend their service life, this study investigates a novel hybrid configuration designed to enhance durability and efficiency. The proposed design consists of three distinct layers: fiber-reinforced polymers tapered shell, lightweight-aerated concrete, and steel tubing. Comprehensive experimental testing of full-scale utility poles was conducted. The Digital Image Correlation (DIC) method was employed to measure deflections and strains across the hybrid poles. Two specific densities of lightweight-aerated concrete were examined: 1200 kg/m3 and 1400 kg/m3. A total of four full-scale utility poles were tested following ANSI standard for utility poles. The failure occurred at the fixed end as expected, and it was observed that the higher-density aerated concrete significantly enhanced the poles’ flexural behavior and reduced tip deflection by 20% compared to the lower-density.
