Abstract

A technique of an approximate analysis of thin-walled spatially curved beams by an assemblage of straight beam elements reported in this paper appears justified and gives favorable results compared with analytically exact solutions. It is concluded that the present straight-beam approximation provides a practical tool for the analysis of arbitrary spatially curved beam, and that the space frame analysis of a spatially curved beam is considered to be valid for design purposes in that excellent accuracy is observed for both displacements and stresses.
