Consider slenderness of wall at ground floor max

Effective length, l0 = 0.75 x (3300 - 200) = 2325 1 = 3.46 x l0 / h = 3.46 x 2325 / 200 = 40.2 Limiting slenderness, 1lim = 20 ABC / n05 where

<Concise Table 5.1> <5.8.3.2(1)> <5.8.3.1(1), Exp. (5.13N)>

where

NEd = 214.6 x 125+ 312 x 15 x 0.7+5029 x 15 +982 x 15 x 0.7* = 268.3 + 32.8 + 754.4 + 103.1 = 1158.6 kN

Acfd = 200 x 1000 x 0.85 x 30 / 1.5 = 3400 kN . n = 0.34 . 1lim = 20 x 0.7 x 1.1 x 1.95 / 0.3405 = 51.5
