Abstract
Using pultrusion process, FRP composite structural members having various cross-section shapes can be produced with unlimited lengths. Because of such reasons, these members are suitable for the application in the construction field. Especially, this material is highly appreciated if the material is to be used in the corrosive environments such as aquatic or oceanic environments due to its high corrosion resistance. However, design criteria for the FRP structural member are not developed yet. So, the research on the development of design guideline is needed ungently. In order to use the pultruded structural FRP member efficiently, the members are composed of thin plate components, and thus, the member is prone to buckle easily and the buckling is one of the governing strength limit states for the design. In this paper, we present the analytical study results pertaining to the buckling behavior of I-shape FRP compression member. In addition, design procedure and flow-chart are also proposed based on the study results including previous experimental results. Proposed design procedure is similar to that in ANSI/AISC 360-10 with minor modification. Therefore, it is convinced that the structural design of pultruded FRP compression member could be done easily by following design procedure proposed in this paper.
