Summary The technology behind splines (mechanically as well as digitally) inspires the intuitive construction process of curved structures, initiated from a flat plane. In the spirit of splines, the shaping process of Vacuumatics is aided by its so-called ‘flexibility control’, which enables Vacuumatics to be applied as a truly flexible, reconfigurable, reusable and self-supporting formwork system. Keywords: Vacuumatics, concrete formwork, spline technology, beam curvature, grid shells. 1. Introduction on concrete shell structures Concrete shell structures, often referred to as ‘thin shells’, have been around since the 1930’s (Fig.1). The design of these thin shells was stimulated by the desire to cover wide spans in an economically attractive manner. Ty
