Development of Hybrid FRP-Concrete Composite Compression Members

Article Preview

The concrete-filled steel tubes have been widely used in buildings and civil structures. However the corrosion of the steel tubes results in the loss of load carrying capacities of the members and, therefore, there is a need for regular maintenance. To mitigate such maintenance issues and prevent the loss of load carrying capacity, FRP composite were suggested as the candidate material. A number of research works has shown that the use of FRP tubes produced by filament winding technique was very effective on the improvement of compressive strength of the concrete-filled FRP tubes (CFFT). However the filament wound FRP tubes did mot contribute to the increase of the flexural strength of a CFFT. In this paper, a new type of FRP tube which consists of several pultruded open sections assembled by filament winding technique is proposed to improve compressive strength as well as flexural strength of a CFFT. The load carrying capacity of proposed CFFT is discussed through the analytical investigation.
