Abstract

The change of dynamic properties of a pultruded SHS beam sections due to fatigue loading and a crack was investigated. A significant change in the fundamental frequencies and flexural stiffness of the pultruded beam due to fatigue loading was observed. There were no significant changes in the fundamental frequencies of the beam which has a purposely created large crack on the surface. However, some noticeable discrepancies were observed in the frequency spectrum which was measured close to the crack.
