Computational analysis optimises uniquely curved form

D-Pod is a multi-use temporary grid shell structure. The architect’s original design (created using parametric software) posited each member as both curving and twisting. However, elements are often easier to fabricate if they are curved in one direction only. Connection detailing is also easier to standardise and therefore less costly if the curvature occurs only along one plane.

The engineering team created a digital tool to reveal the lines of principal curvature in real time to the designer. The architect was able to assess the curve network aesthetically before deciding on a final surface form.
Applying this curvature network constraint early made it easier to remove the twist effect and simplify connections once the design was finalised.

To make the shape of the grid shell more structurally efficient, the engineers morphed the underlying surface into a new position using a self-written script that integrated with the parametric software. Applying the principal curvature tool from the previous exercise to each new surface ensured the resulting structure was buildable.
