A mathematical model of free deformed corrugated flat sheet of rectilinear shell

Abramczyk J.

The paper presents a mathematical model of a flat trapezoidal steel sheet deformed in a planned way during assembly work, to the directrices of the building shell. This model has been based on the results of the experimental tests concerning free deformations of flat sheets. The examined flat sheets were undergoing planned free bend or free twist deformations. The shells shaped with the help of a new method using this mathematical model are characterized by relatively free forms and relatively little effort resulting from free deformations of their sheets at their assembly. This method is more accurate than the methods used so far.
