According to DIN EN 1995‑1‑1/NA, the crack factor kcr may be increased by 30% for softwood in the areas that are at least 1.50 m from the timber grain plane. How is it possible to apply this in RF‑/TIMBER Pro?

Answer

Increasing the crack factor kcr still has to be done manually because the program does not know where is the grain plane defined. To do this, divide the member accordingly by 1.5 m from the grain plain, so that the affected areas can be designed as a separate member (see Figure 01).

Two design cases are now required (File → New Case ...). In Case 1, the members within the 1.5 m are selected for the design. In Case 2, it is necessary to select the members where the 30% should be considered. In Case 2, the kcr value is then adjusted manually in the National Annex settings. Thus, the kcr of 0.65 results for C24, which is entered as shown in Figure 02. In this way, the design is performed with the increased kcr value.
