Bringing together experts from research and practice, Shell Structures for Architecture: Form Finding and Optimization presents contemporary design methods for shell and gridshell structures, covering form-finding and structural optimization techniques. It introduces architecture and engineering practitioners and students to structural shells and provides computational techniques to develop complex curved structural surfaces, in the form of mathematics, computer algorithms, and design case studies.
• Part I introduces the topic of shells, tracing the ancient relationship between structural form and forces, the basics of shell behaviour, and the evolution of form-finding and structural optimization techniques.
• Part II familiarizes the reader with form-finding techniques to explore expressive structural geometries, covering the force density method, thrust network analysis, dynamic relaxation and particle-spring systems.
• Part III focuses on shell shape and topology optimization, and provides a deeper understanding of gradient-based methods and meta-heuristic techniques.
• Part IV contains precedent studies of realised shells and gridshells describing their innovative design and construction methods.

'As the role of computational tools in structural design continues to grow, the form-finding techniques detailed here are more relevant than ever. Bringing together experts in the field, I expect Shell Structures for Architecture will be a valuable inspiration and reference for architecture and engineering students and professionals seeking a deeper understanding, which is essential to make full use of such tools and techniques.'
