Shell and tension surface structures are characterized by complex curved geometries with a potential for structural efficiency and formal quality. To unveil this potential, it is essential to define, modify and analyse complex geometries in an integral way. Describing complex, free-form geometries, within a computer-based design process, non-unifor...

Concrete is the most widely used construction material. Worldwide consumption of cement, the strength‐giving component in concrete, is now estimated to be 4.10 Gt per year, having risen from 2.22 Gt just 10 years ago. This rate of consumption means that cement manufacture alone is estimated to account for 5.2 % of global carbon dioxide emissions.

This paper reviews the methodology employed to teach the design of tensile membrane structures in architecture schools and highlights the importance of developing a deep understanding of the behavioural properties of materials as well as the technical issues related with the structural analysis, construction, and installation of tensile membrane st...
The sensitivity of membrane structures to transient wind loads becomes severe at wide spans and low pre-stress levels of the membrane. At stationary wind loads, the elastic behaviour of the flexible membrane leads to deformations with an associated change of the flow conditions and wind pressure distributions. This effect can be enhanced by time de...
Two recent discoveries that originated from large-scale computational mechanics calculations are discussed.
The first is butterfly effects in massively separated flows commonly encountered in wind calculations.
The second is rogue loads for lightweight structures in complex windfields. Both of these
discoveries have had a profound influence on the...
Windbeanspruchungen bilden für textile Konstruktionen aufgrund ihres geringen Eigengewichts die bemessungsmaßgebende Belastung. Die ausgeprägte Formen-vielfalt doppelt gekrümmter Membrankonstruktionen verhindert eine standardisierte Anwendung normativer Vorschriften. Die Erfassung der dynamischen Bauwerks-reaktionen ist aufgrund des speziellen Trag...
Purpose
– During a routine benchmarking and scalability study of CFD codes for typical large-scale wind engineering runs, it was observed that the resulting loads for buildings varied considerably with the number of parallel processors employed. The differences remained very small at the beginning of a typical run, and then grew progressively to a...

Engineers designing structures must work with incomplete and imperfect models.
In standard design situations, safety provisions in codes implicitly account for these uncertainties.
However, for more advanced design procedures that are not covered by the code, e.g.
when dealing with non-linear dynamic problems, the engineer must explicitly address t...

The susceptibility of membrane structures to fluctuating wind loads due to their flexibility and small inertial mass may lead to severe dynamic amplification of the structural response. This is even more pronounced in the case of low curvature and small prestress values. Thus, the assessment of the structures' stability and safety necessitates the...
Die naturgemäß zeitlich variierende Windeinwirkung stellt bei Leichtbaustrukturen einen wesentlichen Lastfall dar, dessen Beurteilung infolge möglicher aeroelastischer Effekte sowie der typischerweise komplexen Geometrien nur begrenzt mit Windkanalversuchen und Normen/Tabellenwerken möglich ist. Es wird deshalb ein numerischer Lösungsansatz vorgest...
