Principle of panel bracing to carry horizontal force

LVL-C is available in panel widths up to 2500 mm. Wide

panels reduce the number of joints to be nailed or screwed,

thus reducing installation work. LVL-C panels also provide an

ideal solution for higher than normal wall heights. Tables 2.1

and 2.2 show the capacities of 1.2 m and 2.4 mwide single pan-

el sections installed in wooden frames calculated according to

method A of Eurocode 5, subsection 9.2.4. Multiple sections

are summed together to get the total capacity of a wall. Sections

with openings are not taken into consideration, except for the

transfer of horizontal forces to adjacent sections. Anchoring

of robust diaphragms can be critical, especially if the sections

are narrow. Small fastener spacings increase the capacity of the

bracing. 75-150 mm is a suitable spacing for nailing and 100-

200 mm for screwing at the panel edges. At the centre studs of

the panels the fastener spacing can be doubled without reduc-

ing the bracing capacity. The capacities are based on the panel,

nail and stud combinations specified in Section 5.7.
