Center of compression
In accordance with EN 1993-1-8, Art 6.2.7.2 (2) for bolted end-plate connections, the center of compression is assumed to be in line with the center of the compression flange of the connected member.
Within SCIA Engineer:
- In case of a presence of a haunch with flange in compression, the center of compression is assumed to be in line with the center of the inclined compression flange of the haunch.
- In case of a presence of a plate haunch in compression, the center of compression is assumed to be in line with the center of the compression flange of the connected member. In fact in the same location, like if the plate haunch is not present, therefore it is not possible to define component "Stiffener at haunch end" in such case.
The inclination of the beam/haunch flange is taken into account in calculation of leverage arm for Mj,Rd determination.
The size of the haunch weld ac has no impact on the location of the center of compression. (See also chapter: "Haunch with flange")
In the splice connections, the positions of center of compression for each side may be located differently. Maximum difference may be equal to the minimum thickness of the adjacent beam/haunch flanges from both sides. For any further calculations, the center of compression is taken from the side, where the bolts have been activated.
