Study on the Bending Performance of Composite H-Shaped Piles

Abstract There has been a great increase in the number of structural members composed of two or more materials with different stress–strain distributions. This study investigated the bending performance of composite H-shaped piles subjected to bending moments. Load–displacement hysteresis curves were analyzed using limit state analysis, and eight specimens—six composite H-shaped piles made of reinforced concrete and H-shaped steel beams (i.e., composite H-shaped piles) and two conventional H-shaped steel piles—were tested using a loading apparatus. The test results show that the ductility capacity of the composite H-shaped pile is 138 % more than that of the conventional H-shaped steel pile.
