Optimization of stadium roof structure using force density method

The paper presents the application of a form finding procedure to the optimization of spa-tial structures. In contrast to typically form finding procedure, focus is given to the struc-tures which are primarily loaded by compressive forces. According to the tensile-compressive analogy, finding the form of an analogue tensile structure, bending moments in the structural elements can be eliminated. The geometry optimization is performed itera-tively by the force density method through the kinematic constraints which provides the final shape of structure does not differ significantly from the initial. Finally, the method is applied to geometry optimization of the roof stadium Kantrida in Rijeka.
