Fabrication Aware Form-finding: A combined quasi-reciprocal timber and discontinous post-tensioned concrete structure

This paper describes a design and construction method that combines two distinct material systems with fabrication aware form-finding and file-to-factory workflows. The method enables the fluent creation of complex materially efficient structures comprising high populations of geometrically unique parts. The first material system employs a novel rotated joint design to allow the structural tuning of quasi-reciprocal timber frame elements fabricated from multi-axis machined plywood sheet stock. The second em-loys discontinuous post-tensioning to assemble unique precast concrete components into load-bearing structures, significantly reducing or eliminating false work during as-embly. The method is tested with the construction of a research pavilion.
