Topology Optimisation for a Concrete Slab

Concrete is one of the most consumed products in the world, with more than ten billion tonnes being produced every year. Optimising the use of concrete in prefabricated components can have a global impact in reducing material costs and the carbon footprint of buildings and infrastructure. However, optimisation algorithms often result in highly complex geometries […]

3D Printed Slab

Topology optimisation can be used as a design method to reduce material without affecting the functionality of an object. Despite being one of the most demanding economic sectors in terms of material consumption, the construction industry has not yet adopted such design methods. This is generally because computational optimisation algorithms produce complex solutions which are difficult […]
