The Flexural Performance Evaluation of Hybrid Concrete Filled FRP Tube Connection

Abstract

In the construction industries, in order to compensate material disadvantages of existing construction material (concrete, steel, wood, etc.) and satisfy requirements of the structural performance, research on durable and outstanding corrosion resistant fiber reinforced polymeric plastic (FRP) is actively underway. In general, a pile cannot be produced with unlimited lengths because of the size of the manufacturing machine and transportation to construction site. Therefore, the connection of pile and structural integrity of connection should be considered in the pile design. In this paper, hybrid FRP-concrete composite pile (HCFFT) was investigated by focusing on the connection of HCFFT members. The connection capacity of HCFFT was evaluated by the experiment and the finite element analysis. From the results appropriate connection method of HCFFT is discussed.
