Z: diagonal tension anchor force on
the corner elements.
PERI recommends temporary bracing
of the corner elements in the case of
expected wind speeds of more than
100 km/h. See Section "Bracing the
Corner Elements" on page 110.

Load cases
A: Working conditions
Wind load from wind suction with q(z) = 0.50 kN/m²
(v = 100 km/h)
100 % live load on one level,
50 % live load on a second level.
Without bracing.
B1: Storm conditions
max. wind load from wind pressure w

> 0
no live loads
Bracing not effective (Z = 0)
