Rooftop Studio Extension for Oxford Brookes School of Architecture

The roof structure for this new studio space had to be of lightweight construction, being built on an existing flat roof. An orthogonal grid of continuous aluminium extrusions was chosen as the structural form, with single bolt connections at each cross over.
The spherical surface is to be created by 'jacking down' a flat grid of extrusions into position over a series of vertical props. The deformation of the shell is developed by a combination of rotation of the single bolt connections and bending of the extrusions.
Physical models were built to examine the behaviour of the grid shell during this erection preceedure.

A non-linear analysis programme was used to model the construction sequence and derive the final dimensions of the cladding panels.
