Methodology and validation of performance-based structural design applied to the conception of a lattice wind tower

Abstract

This paper presents a study based on the performance design process by using parametric and algorithmic models development. This study integrates the structural analysis and the design to generate complex geometric structures, based on manufacture and assembly parameters. The used methodology is based on the Performative Model, in which the structure shape is generated using performance criteria. In this perspective, the complex structures development is only possible by reverting de shape conception process, in which its generation is linked to the geometric, material and load parameters. Therefore, the structural engineer not only participates in the evaluation phase, but also in the early stages, creating an exploration and production process of common knowledge among architects and engineers. For the purpose of investigating this approach, this work presents the design of a conceptual lattice wind tower.
