An advanced analysis of spatial interaction between the elements of tubular scaffolding has been carried out at the Czech Technical University in Prague. Experiments focusing on rotational stiffness of the common couplers have been performed. The resulting stiffness (semi-rigid connections), eccentricities etc. have been implemented into spatial models and a detailed GNIA analysis followed. The results of calculations performed on simple and complex models and a recommendation for the most effective computation models has been presented. The recommendations have been implemented in the following research of the scaffold anchoring. This paper research was essential for the related development of the new scaffold anchor, which successfully overcomes the problems with insulated building facades.
