Sway Stiffness of Scaffold Structures

This paper describes the analysis of large scaffold structures by 2- and 3-dimensional models. The models have semi-rigid joints between scaffold members. A prototype structure was analysed and the results were compared with test data from Stuttgart. Both 2- and 3-dimensional analyses gave good correlation. The basic scaffold, 30m high x 20m wide, given in BS 1139 was then analysed. The 2-dimensional models gave excessive displacements and subjected the windward standard to uplift forces. A 3-dimensional model with small joint stiffhesses showed the beneficial effects of interactions between the front and rear faces of the scaffold in producing acceptable results. M.H.R. Godley and R.G. Beale
