10A. DIMENSIONING PART 1/4

To set the "Tensile" parameters and check the position of the holes (EC3 chapter 1.8 §3.5): For the holes define the distances from the ends, the diameter and the number of rows on the torso and tread. In the case of an L section, set the parameters at the bottom of the box. The rationale here is to specify whether the application during the tensile test take into account the bolt holes of the connections in order to account for reduced tensile strength of the cross- section. If you decide to provide data you will derive it, for the specific layer (e.g. Metallic Supports) from the corresponding connection checks you should have already performed. You must therefore have previously checked the connections before you can give data here. The safety factor for all checks is predefined and equal to unity, which means that the program calculates the ratio of the corresponding stress to strength and if this ratio is greater than unity, a failure occurs.
