Konstruktion und Berechnung von explosionshemmenden Seilnetzfassaden

Nowadays the threat of terrorist bomb attacks on buildings is very real, and we frequently hear about tragic consequences of such attacks. To protect the public against such horrible acts, the engineering community has embarked on developing technologies and concepts that can economically provide life safety measures to vulnerable structures. The design philosophy is primarily to save lives and prevent injuries, and secondarily to protect buildings, functions, and assets. The design criteria take a balanced approach to safety, considering cost effectiveness and acknowledging acceptance to some risks.
For cable net facades with point supported glazing new design methods and solutions are developed. These methods include new tools for the numerical evaluation of facades under impulsive blast loads. New design solutions include appropriate connections to the supporting structure (cable end support) which are able to dissipate a significant part of the blast wave energy and positively influence the structural post-failure behaviour.
