Abstract

A finite element having seven degrees of freedom at each node is developed to study the stability problem of thin-walled fiber-reinforced plastic (FRP) structural members. The influence of the in-plane shear strain on the stability of the members is taken into account. The shape functions for the rotation and unit length rotation induced by warping are derived. The static and geometric stiffness matrices of a general beam element are established on the basis of the developed shape functions. The bifurcation buckling problem of thin-walled pultruded open-sections subjected to various loading and boundary conditions is examined through a number of examples. It is shown that the influence of the shear strain on the buckling capacity of the FRP structural members is significant and must be taken into account in the design of such members.
