04/18/2018_Tension facades and cable trusses use high tensile cables or stainless steel rods to impose the loads of the facade on the main structure and rely on the introduction of prestress forces into the tensile elements of the truss to provide stability.
This system gives transparency and dematerialization to the structure and cables are tensioned to create sub-trusses with minimal visual obstruction.
Cable properties are:
- being flexible
- have exceptional tensile strength to mass ratio
- work solely on a tension design
- rod and metal frame systems may use both tension and compression
- in terms of engineering these systems are very complex comparing to other systems
This system is especially ideal when the facade design is very tall. The result is a cost effective, easy-to-maintain facade construction that retains minimal vertical trusses where structure helps to spread out the forces put on the building, while keeping the sightlines very clean inside and out.
