AbstractThis paper investigates the development of a subtractive material technique whereby plywood sheets are slotted in order to achieve variable stiffness, resulting in articulated bending curvatures across global surface geometries. Derived from the differentiated distribution logics found in natural systems, this research employs material computation strategies along with digital analysis and fabrication techniques for the design of performative variable-stiffness structures. The material technique was tested in its application to a research pavilion undertaken by staff and students in the Emergent Technologies and Design program at the Architectural Association School of Architecture during the academic year 2012/2013. Through a process of optimisation the proposed design was adapted to meet structural and programmatic demands. Upon analysing a series of successes and failures with its first installation at Hooke Park, the structure was redesigned and installed at the Architectural Association’s Projects Review in London.
