Abstract

The paper presents a concept of shaping of the space structures formed by means of post tensioning. Basic structure is completed as a plane form with a bottom chord made of the cable. Shortening of the bottom chord allows "self-erection" of the structure. Final shape i.e. curvature of the upper chord is a result of interaction between bending rigidity of the structure and the tensile force in the cable. Struc- tures more rigid in the central part than at the sides gains curvature with smaller radius while structures more rigid at the sides than at the central part gains curva- ture with bigger radius. The simple way of changing global rigidity of the structure is to change its height. This concept allows to easily create a wide range of struc- tures suitable for any purpose especially of
