Die Stahlbetonbemessung für den Brandfall erfolgt nach dem vereinfachten Verfahren gemäß EN 1992-1-2 Abschnitt 4.2. Dabei wird die im Anhang B.2 beschriebene "Zonenmethode" benutzt: Der Querschnitt wird in eine Anzahl paralleler Zonen gleicher Dicke unterteilt und deren temperaturabhängige Druckfestigkeit ermittelt. Die reduzierte Tragfähigkeit bei Brandeinwirkung wird so durch einen verkleinerten Bauteilquerschnitt mit abgeminderten Festigkeiten abgebildet.
Le présent article traite des éléments dont la section est soumise simultanément à un moment fléchissant, à un effort tranchant et à un effort normal de compression ou de traction. Cependant, dans notre exemple nous n'intégrerons pas de sollicitations dues à un effort tranchant.
Using the RF-TIMBER CSA module, timber column design is possible according to the CSA O86-19 standard. Accurately calculating timber member compressive resistance and adjustment factors is important for safety considerations and design. The following article will verify the factored compressive resistance in the RFEM add-on module RF-TIMBER CSA, using step-by-step analytical equations as per the CSA O86-19 standard including the column modification factors, factored compressive resistance, and final design ratio.
Using the RF-TIMBER CSA module, timber beam design is possible according to the CSA O86-14 standard. Accurately calculating timber member bending resistance and adjustment factors is important for safety considerations and design. The following article will verify the factored bending moment resistance in the RFEM add-on module RF-TIMBER CSA using step-by-step analytical equations as per the CSA O86-14 standard including the bending modification factors, factored bending moment resistance, and final design ratio.
Requirements for the design of structural stability are given in the AISC 360 – 14th Ed. Chapter C. In particular, the direct analysis method provisions, previously located in Appendix 7 of the AISC 360 – 13th Ed., are described in detail. This method is considered an alternative to the effective length method, which in turn eliminates the need for effective length (K) factors other than 1.0.
