1. Introduction

Dynamic relaxation (DR) [1,2] is a dynamic analysis procedure where one is interested in the final rest state of the structure, that is, the static solution after the dynamic oscillations have been suf- ficiently damped. The structural system is considered to be in equilibrium after a convergence criterion is satisfied, for example, when the balance of internal and external forces is suitably close relative to some tolerance. The initial geometry of the structure need not be close to the final rest state, and so the process may be initialised from an approximate geometry and found after the external loads are instantaneously applied. The method is particularly adept at solving large displacement problems and has found application withanalysing assemblies of cable, bending and membrane elements, and is used extensively for tensile structures [3]. There are various examples in the literature of using DR to analyse beam elements. Work related to bending elements stabilised by membranes can be found in [4]; in [5], six degree-of-freedom elements were used to analyse the erection and loading of double-layered timber beams for grid-shells, with an optimisation method for variable crosssection depths; tubular glass-fibre-reinforced grid-shells have been investigated by [6], and [7] looked at bending elements supported by cables and/or cable-nets. Although membrane elements are not investigated in this research, constant strain triangular elements could be used, as formulations in the literature describe the behaviour of the membrane element via the edges of the faces to give an equivalent cable-net system. Therefore by creating a relationship between membrane stresses and edge link tensile forces, the methods described here-in for net structures may be extended readily for application to membrane elements. Further literature on membrane elements in the dynamic relaxation method can be found in [2,8,9] and [10].
