Abstract
Fiber-reinforced polymer (FRP) pultruded profiles are increasingly used in the construction industry as primary and secondary load-bearing members, because of their good corrosion behavior, low weight, and high mechanical properties. In this paper, the effect of the actual distribution of the applied compressive stresses on the flexural-torsional buckling load of FRP structural members is analyzed. The static behavior is described by means of the exact theory of thin-walled isotropic beams, developed by Capurso in 1964 and generalized by the authors to transversely isotropic materials. A numerical example is presented for the I-section, showing that the critical load of FRP pultruded profiles may be sensitive to the uniformity of application of the load and hence predictions based on St. Venant's principle may result unsafe.
