ResumoThree-dimensional geometric non-linear analysis of guyed towers using linear isoparametric formulation within an updated Lagrangian coordinate framework is presented. The complex non-linear behaviour of the guy cables is simplified by the equivalent modulus approach. Shear locking of the two-noded beam element is corrected by reduced order of integration and altering the elastic coefficient for the transverse shear. The formulation is general enough to include transverse shear effects, eccentricity of the centroidal axes from the beam shear centre and the product of inertia of the beam cross-section. A typical guyed tower example is solved and results are compared with the published work.
