Fiber reinforced composite steel pipe is a potential alternative to conventional pipe materials, particularly for high pressure applications. While composite-steel hybrids offer a number of advantages, the design (or sizing) of the pipe requires the use of specialized analysis tools such as finite element modeling. The objective of this paper is to provide a series of closed-form equations which can be used to determine the stress-strain response for both the composite and steel components. Coupled with an appropriate failure criteria, these simple equations can be used for preliminary design and sizing purposes. Solutions are developed for fixed (restrained) ends and free (unrestrained) boundary conditions. Predictions are compared to advanced finite element models and experimental data to demonstrate their utility.
