Abstract

The paper presents a three degree of freedom formulation for the dynamic relaxation modelling of tubular bearing systems applied in arch supported membranes and closed hoop supported cable net bridging structures. For tubular arch structures the numerical modelling method has been validated against analytical and finite element models with span/rise ratios up to 20. Beyond this, and particularly as arches flatten under limit state loads the method becomes impractical. A revised process is given for the modelling when approaching failure states, and is applied and validated for the case of a very flexible arch supported membrane structure subject to snap through buckling. The paper also illustrates how the torsion/bending theory can be used to cover different closed hoop supporting systems, and the numerical modelling is applied to a multi-span bridging structure employing tubular hoops of various sizes and shapes around which spiral a prestressed cable network.
