Tying systems: the minimum force on an internal beam line - the values of q3 and Q4
Eurocode 2 part 1-1: Design of concrete structures 9.10.2.3 (4)
In floors without screeds where ties cannot be distributed across the span direction, the transverse ties may be grouped along the beam lines. In this case the minimum force on an internal beam line is:
| Ftie = q3⋅(l1 + l2) ≥ Q4 | (9.16) |
where:
- l1, l2
- are the span lengths (in [m]) of the floor slabs on either side of the beam.
Recommendation
The recommended value of q3 is 20 kN/m and of Q4 is 70 kN.
