Torsional Analysis of Lattice Towers

Cao, J.J. / Bell, A.J. / Xu, K.J.

This paper is concerned with the calculation of forces and displacements arising from the torsion loading of lattice towers. Square, rectangular and triangular towers with parallel legs, sloping legs and combinations of parallel/sloping legs are considered. New formulae are presented for determining forces and displacements based on formulae similar to those used in torsional theory of thin-walled bars. The formulae are simple and accurate and can be used in practical situations, particularly at the initial design stage or during reassessment of structures for revised loading. The accuracy of the formulae has been confirmed by finite element analysis. Two examples are included to demonstrate the use of the formulae.
