allgemeinen Windkanalversuche die Grundlage bilden. Das gilt sowohl für das Windklima am Bauwerksstandort als auch für die aerodynamischen Beiwerte, für die im. Die Angaben der Norm lassen sich durch Sonderuntersuchungen zuschärfen, soweit die Regelungen das nahe legen und der zusätzliche Aufwand gerechtfertigt ist. The framework is exemplarily applied to the wind load model of the Eurocode.ĭer folgende Beitrag befaßt sich mit den klimatischen Einwirkungen auf weit gespannte Dächer. Based on this, we develop a framework for adapting the safety concept to ensure that advanced models lead to the same level of safety as standard models. We comprehensively discuss the role of hidden safety in codified structural design and its effects on the reliability and material consumption.
While the advanced models might be associated with smaller uncertainty, which increases reliability, the loss of hidden safety can decrease the reliability. On the other hand, it will affect the structural safety. But what happens if one utilizes more advanced design models without the implicit conservatism of the simple models? On one hand, an advanced design method has the potential to result in more optimized designs. This leads to additional “hidden safety” in the design. To ensure sufficient safety with simplified models, parameters of these models are often chosen conservatively. Structural design codes are deliberately kept simple to facilitate the design process.
