钢材的防火性能较差。 The thermal expansion for increasing temperature is very high compared to that of other building materials, and might result in effects that were not present in the design at normal temperature due to restraint in the component. As temperature increases, steel ductility increases, whereas its strength decreases. Since steel loses 50% of its strength at temperature of 600 °C, it is important to protect components against fire effects. In the case of protected steel components, the fire resistance duration can be increased due to the improved heating behavior.
Für eine schnelle Übersicht der verwendeten Querschnitte können die Stäbe farblich je nach verwendetem Querschnitt darstellt werden. Mittels rechter Maustaste im Arbeitsfenster kann dazu aus dem Kontextmenü "Farben in Grafik nach" → "Querschnitte" gewählt werden. In den aktuellen Programmversionen wird dazu auch ein Panel mit einer editierbaren Farbskala ausgegeben.
美国木材协会(AWC)发布了 2018 年版的木结构国家设计规范(NDS)。 This is the second edition of the NDS to contain a chapter dedicated to cross-laminated timber (CLT) design. Therefore, a couple of revisions were included in the 2018 NDS when compared to the previous 2015 Edition.
