Abstract

An experimental study dealing with testing noncircular glass-reinforced plastic pipes under compression was conducted. The testing program included four pipe shapes (box, flat elliptic, egg, and round) loaded under the same condition using the parallel-plate test method. Strain measurements and pipe deflections were recorded from which pipe shape factors and stiffness were estimated. The experimental results showed that circular and flat elliptical pipe shapes are, respectively, the stiffest and most flexible ones among all tested pipes. Moreover, the experimental results showed a good agreement with the simulated results of the same tested samples.
