Form-Finding and Optimisation Theory and Tools
The construction industry is one of the most resource-intensive sectors. These resources –such as energy, raw materials and available land for both the building itself and the waste generated – are largely non-renewable and are rapidly decreasing. Due to the large size of buildings and bridges, their long serviceability life, and the large number constructed annually, our field in a privileged position to radically rethink the approach to design and to substantially advance sustainable development. This opportunity underlines the relevance of this research. In recent years, research in the field of the design of sustainable structures has mainly focused on quantifying the environmental impact and life cycle cost of existing structures, and to a lesser extent new structures, maintenance and replacement modeling and strategies, reliability-based life cycle management, optimization of maintenance and management of deteriorating structures and life cycle design of new structures. A life cycle assessment approach quantifies the environmental effect of a design once the design is completed. Unfortunately, little attention has been paid to developing structural design methodologies and tools that advocate sustainable design through minimal use of materials. Traditionally structural design is aimed at well-defined codes that guarantee structural strength and serviceability. These codes however set no specific requirements regarding the structure’s environmental impact. Faced with the challenge of building more economically and sustainably, structures should be conceptualized with material and current available fabrication techniques in mind. The advent of digital modeling, optimization, form-finding and manufacturing technologies have given designers a new toolbox. Architects and artists have eagerly explored some of these methods to design and construct sculptural forms. My research develops and validates design methodologies that match untested design ideas to material-efficient and constructible structures through the development of numerical algorithms and tools.
