Abstract
Building shapes throughout history have been created with architectural, structural and other purposes in mind. Form can be embedded with technical knowledge that complement the architectural and esthetic aspects of buildings and enrich their design. Shells in particular have a long tradition of being structurally sound as well as architecturally significant. Complex curved surfaces present a great deal of opportunities in their ability to evenly distribute sound energy inside concert auditoria, as well as carry structural loads efficiently, with very little material and with very interesting shapes. This paper presents the use of multi-objective Genetic Algorithms (GAs) with the purposes of generating free-form surface shapes that are both structurally and acoustically efficient. Pareto fronts representing the non-dominated solutions for both structural and acoustical fitness functions are presented.
