Analysis of calculation models of scaffolding constructions in light of experimental tests results of constructive scaffolding module

The concern of the article is the analysis of multiple computational models of scaffolding construction, taking into account the experimental results obtained for a representative scaffolding construction module. Analyses of 25 distinct models have been performed, allowing selecting models that most accurately predict deformations of the real construction. The article deals with the issues of elastic-plastic second-order analysis in relation to the working anchored scaffolds and it is focused on the standardization of computational models for engineering calculations. Including in calculations the plastic bearing capacity reserve and using objective calculation procedures, allows optimal designing of the scaffolding and evaluating of the load capacity. Structural model analyses were carried out in terms of their conformity with the actual construction. For comparative purposes, the results of the analyses of individual models were evaluated according to different verification formulas to determine the extent of their applicability. The purpose of the article was to test the behaviour of the system under the influence of constant horizontal forces reflecting the influence of wind and rising from zero until destruction due to the vertical load.
