Novel Parametric Knowledge Modelling approach applied to Viaducts

This paper presents a novel approach to modelling and documenting design knowledge: to use parametric technology to explicitly store knowledge which exists in a group of people (such as a company), so that it can be reused over many projects and grow over time when more projects are designed. This approach has been applied and tested on a test...

Topology optimisation of a concrete floor slab guided by manufacturability constraints from a vacuumatic formwork

This paper presents a design for a topology-optimised concrete floor slab, of which the structural optimisation process is guided by manufacturability constraints from a vacuumatic formwork. Ihe design has been obtained using an open-source, tliree-dimensional topology optimisation algorithm. Traditional floor systems are cost-optimised but can...

The use of SCC and textile reinforcement

In an earlier article (CPI issue of August 2011 [1]) a method was presented for producing precast curved panels with a thickness of a few centimeters using the 'flexible mould method'. This method is the central theme in the PhD study of the first author on the realization of freeform architecture in concrete. The concrete panels manufactured...

Concrete shell structures revisited: Introducing a new 'low-tech' construction method using vacuumatics formwork

This paper provides a new perspective on the construction process of concrete shell structures and introduces a new cost saving approach for constructing (single curved) concrete shells using Vacuumatics formwork.
