Static analysis of taut structures

Abstract

The article presents a general framework for the nonlinear equilibrium analysis of taut structures, such as cables and membranes. Distinction is done between geometric and constitutive stiffness, and all the relevant matrices for truss and membrane finite element static analyses are derived, including the effects of sliding cables and following forces (such as wind pressures). The peculiarities of the design of taut structures are briefly discussed, considering the design of an existent membrane structure as a benchmark.
