Additive manufacturing and 3D printing are rapidly developing digital fabrication techniques (Lu et al. 2015). After the first steps in small scale printing of metals (Frazier 2014) and plastics (Gibson et al. 2014) have been made, research from various groups around the world is now also focusing on large scale printing in concrete (Lim et al. 201...

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. The design has been obtained using an open-source, three-dimensional topology optimisation algorithm. Traditional floor systems are cost-optimised but can have...

About 40-50% of global raw materials are currently used in the building industry in the assembly/construction phase and in the use phase of the building and are responsible for 40-45% of total worldwide anthropogenic carbon dioxide emissions (Huovila [5]). These problems have led to the development of legislative policies, regulations and targets t...

A solar updraft tower is a type of power plant which uses solar irradiation to generate electricity. It consists of three elements: a solar air collector, wind turbines and a chimney. The proposed concepts for this chimney schematise it as a 1-km-tall reinforced concrete shell, which are vulnerable to resonance induced by storm actions. This paper...

The adoption of computation in the building industry has led to the development of a range of tools intended for design. Although commonly used for detailed analysis (FEA) and documentation (CAD/BIM), few tools address the needs of the early design stages for flexibility and quick, insightful feedback and documenting the justification of design cho...

A High Performance Fiber Reinforced Cementitious Composite (HPFRCC) is a tensile-hardening cementitious material with a post-cracking ten-sile strength equal to or higher than that of an un-cracked cross-section. As a con-sequence, the tensile strength can be taken into account for the structural design, which allows sophisticated computational met...
Article
Fabric formwork entails the use of fabrics as the main contact material for a concrete mould. The fabric is either hung or prestressed in a supporting falsework frame. Beams or trusses cast in fabric formwork are inherently non-prismatic and have been shown to offer potential for structurally efficient shapes. The casting of beams or trusses in fab...

During the design and engineering process of buildings and structures an enormous amount of data and information is produced. Logic, knowledge and experience is employed during this process by the designers and engineers to finally come to the design result. Because this information can not be fully recorded by software, a huge amount of informatio...

p. 589-597 Structural design deals with solving the complex problem of the realisation of a building from the initiation to final execution. During this process many complicated sub-processes take place which handle with large amounts of design information. Following the Structural Design Tools approach (Coenders [2]) computational design attempts...

In complex structures, cast nodes are often applied to seamlessly and fluently guide the flow of forces through the joints in the structure. Computational optimisation could play a role to automatically form structural joints, with this kind of flow of forces, as a fast design tool and discovery technique. It could be used to give a crude indicatio...

In the current practice of structural engineering progressive collapse usually does not get much attention during the design of a building until the late stages of the building design. An important cause might be that currently no (computational) design tools exist for progressive collapse failure. Quick Building Assessment Tools form one of the fi...

p. 1145-1153 Computer-aided design tools can be of great assistance in the design process. However, commercial software typically caters to the optimisation of one objective and does not address the fact that real world problems tend to be solved by assessing the trade-offs between multitudes of competing objectives. Therefore the question is posed...
