Abstract

The material such as steel or concrete has used to civil structures such as drainage pipes , but many problems such as corrosion in using steel and concrete pipes have happened. So, Necessity of developing new materials with high strength and anti-corrosion has been topic recently. One of this topics is study about ERP pipe. The strength of orthotropic FRP tends to be higher than it of isotropic FRP, the buckling problems can be significant in materials with high strength. thus, the study about bucking of orthotropic FRP-pipe is needed. In this study, buckling analysis of laminated cylindrical composite structures subjected In ply angle change under external uniform pressure was performed.
