Original Abstract

The article describes behaviour of the structure of a prefabricated winder wooden staircase with central stringer on the material basis of Scots pine (Pinus sylvestris L.). It focuses on static behaviour of this structure. An analysis was performed with the use of 3D numerical modelling with the finite element method using ANSYS calculation system. The numerical analysis with an orthotropic material model and Hoffman and Tsai-Wu interactive failure criteria showed critical points of this type of analysed staircase. Subsequently, selected critical points were experimentally tested for static loading on models of wooden fragments of the staircase in the scale of 1:1. Experimental tests and numerical analyses pointed out the importanceof a suitable choice of a material model of wood and the necessity to pay particular attention to designing of these points. The results and conclusions could be helpful for designing of a prefabricated winder wooden staircase with the central stringer.
