Sumario:Optimisation techniques may be effective in finding alternative geometries of shell structures to improve their mechanical behaviour, particularly avoiding or reducing the bending moments. This paper shows how the field of use of computers may be widened using these techniques in the design of concrete shells, allowing the user to obtain optimum designs complying with the design conditions. Some optimum geometric designs of an actual concrete shell were found, presenting an aesthetic appearance similar to that initially planned by the designer. The results confirm that significant improvements in the structural behaviour may be achieved with only slight geometric changes.
