Multi-Layer Planar Reciprocal Frames: A Structure Prototype for Floor and Roof Systems

This proposal centres on developing a structure prototype using planar Reciprocal Frame (RF) structures that can be adapted to a variety of floors and flat roofs for different building programmes. RF’s use of short members to create long spans, the simplicity of the joint where two members meet and finally the repeating pattern the system creates are developed in two models, scale 1:10. The prototype is modular, flexible, extendable and guarantees frequent and regular void spaces which lend themselves to lightwells and service voids. It can be made from a kit-of-parts suitable for pre-fabrication and rapid assembly. Also, by assembling RF frames one layer atop another, the need for temporary supports during construction is negated. This RF prototype addresses efficiency in the use of building materials and the potential re-configuration of buildings and their elements as per the circular economy.
