Abstract
Accurate prediction of buckling strength is essential for the reliable, efficient, and safe design of thin-walled pultruded fiber-reinforced polymer (PFRP) columns. This paper presents the comparison of the
existing six closed-form solutions based on the test database. Analysis of the experimental data from the database indicates that the Euler formula is the most unconservative of all equations (except for the equations recommedned by Strongwell Corporation) in predicting the global buckling loads of PFRP columns. The Engesser and Haringx shear correction formulae exhibit better performance than the Euler formula. The equation recommended by Fiberline Composites is observed to underestimate actual
buckling capacity and is the only conservative prediction of those equations. The equations proposed by Strongwell Corporation appear to be incapable of reasonably predicting the global buckling loads of PFRP columns. The formula developed by Zhan et al. gives the most accurate predictions.
