The capacities are given for one SPF, where the header and purlin are prevented against rotation

The published characteristic capacity is based on short term load duration and service class 2 according to EC5 (EN 1995). For other load duration and service class, please refer to the ETA to get more accurate capacities

The capacity for connection with 2 SPF is the sum of the single capacities.

$\sum\frac{F_{i,d}} {R_{i,d}}\le1$
