Influences of structural systems on form and space integrity of free-form buildings: an investigation through case studies

Free-form architecture is a contemporary design language that challenges traditional geometric forms in architectural design. It is characterized by its complex and irregular shapes, which are mainly achieved through advanced digital design and fabrication technologies. However, free-form buildings may overly prioritize form over structural rationality and spatial quality because of their irregular nature. Therefore, the potentials and limitations of their flexibility need to be investigated through the architectural components, structure, form, and space. This thesis investigates the potential of structural systems which are an aesthetic and inventive medium for shaping and experiencing free-form buildings. It is intended to determine and evaluate structural systems' influences on form and space integrity of free-form buildings. With this framework, seventeen selected pioneering free-form buildings are investigated through an in-depth analysis that is resulted in a tabular report which involves specific structural, formal, and spatial analysis with a general assessment part. As a result, it has been determined that the design process for a free-form building needs to be more integrated to ensure the integrity of form and space. Moreover, the findings indicate that contemporary free-form buildings contain overly complex hierarchical structural organization, such as primary and secondary systems. Consequently, designing structural systems that seamlessly integrate with such buildings' form and spatial configurations necessitates a distinct perspective and specialized design knowledge. In line with these findings, this thesis suggests that an integrated design process should be supported by a comprehensive knowledge and understanding of structural systems, their hierarchical organization and how they simultaneously effect formal and spatial configurations.
