clarifications. As with reinforced concrete, some work is needed to evaluate these tie

forces relative to US and DoD construction.

As described in the footnote of Table 6-2, lateral supports are defined, using

the definition of Ft in Section 6-2.4, as:

1) An intersecting or return wall tied to a wall to which it affords support, with

connections capable of resisting a force of Ft in kN per meter height of wall

(0.45 Ft in kips per foot height of wall), having a length without openings of

not less than H/2 at right angles to the supported wall and having an

average weight of not less than 340 kg/m2 (70 lb/ft2).

2) A pier or stiffened section of the wall [not exceeding 1 m (3.3 ft) in length],

capable of resisting a horizontal force of 1.5 Ft kN per meter height of wall

(0.45 Ft in kips per foot height of wall).

3) A substantial partition at right angles to the wall having an average weight

of not less than 150 kg/m2 (30.9 lb/ft2), tied with connections capable of

resisting a force of 0.5 Ft kN per meter height of wall (0.15 Ft in kips per

foot height of wall) and having a length without openings of not less than H

at right angles to the supported wall

Figures B-8 through B-10 are schematics of these definitions.
