The load capacity belongs to a load group with the modification factor k_mod.

1) R_4/5,k is determined for beam width b = 75 mm and essentricity e = 130 mm. See ETA for other values of b and e.

If the overall structure prevents the rotation of the purlin, the load values R_1,k and R_2/3,k in an assembly with only one bracket equal to half of the given value in table 2. See ETA if the purlin is able to rotate.

* The published characteristic capacity is based on short term load duration and service class 2 according to EC5 (EN 1995) – k_mod = 0.9. For other load duration and service class, please refer to the ETA to get more accurate capacities

To obtain the resistance values for a single bracket, the values in the above table should be divided by two, provided that the supported beam is locked in rotation. Please consult our ETA-06/0106 if the beam is free to rotate.

Technical information

F1: tensile force in the central axis of the angle-bracket
Particular situation of a fastening with only one angle-bracket:

If the overall structure prevents the rotation of the purlin or the post, the tensile strength is equal to half of the given value for two angle-brackets.
Otherwise, the connection resistance depends on the « f » distance between the vertical contact surface and the point of load application.

F2 and F3: shear lateral force
Particular situation of a connection with only one angle-bracket:

The resistance value to consider is equal to half of the one given for two angle-brackets.

F4 and F5: transversal force directed towards or opposite the angle-bracket

The connection resistance depends on the « e » distance between the base of the angle-bracket and the point of load application.
To consult corresponding loads, contact us.

Only F1, F2 and F3 forces for connections with 2 angle-brackets are present on this sheet.
