Fiber reinforced polymer (FRP) composite materials have many advantages over traditional building materials. They are becoming more and more popular in civil engineering applications. FRP pultruded tubes are easy to fabricate and can be easily assembled for different applications. In this paper, FRP tube assemblies of variable size, fiber material, tube wall thickness, and different installation are studied using finite element analysis. The deflection and stress distribution are listed for each case. When compared to experimental results, the numerical analysis shows good correlation. Data gained in this study can be used for design and optimization of FRP tube assemblies for bridge deck construction and similar applications in civil engineering.
