Combinations of actions at ground st floor

a) At ULS, for maximum axial load, Wk is leading variable action.

= 1.35 (214.6 + 50.1) + 1.5 x 502.9 + 1.5 x 0.7 x 35.7 = 357.3 + 754.4 + 37.5 = 1149.2 kN / m

where M

moment from 1st order analysis 28.4 kNm / m

= l0 / 400 = 2325 / 400 = 5.8 mm 0 = h / 30 > 20 mm = 20 mm = 28.4 + 0.0058 x 1149.2.1 > 0.020 x 1149.2 = 28.4 + 6.7 > 23.0 = 35.1 kNm/m

++ Ignoring effect of landing.

** Assuming wind load is lead variable action.

n = NEd / Acfd k e e b) At ULS, for minimum axial load, Wk is leading variable action.

= 1.0 x 214.6 - 1.35 x 50.1 - 1.5 x 502.9 + 0 x 35.7 = -607.4 kN / m (tension) = 28.4s8 + 0.0058 x 607.4 > 0.020 x 602.4 = 28.4 + 3.5 > 23.0 = 31.9 kNm / m c) At ULS, for maximum out of plane bending assuming Qk is leading variable action. NEd = 1.35 (214.6 + 50.1) + 1.5 x 35.7 + 1.5 x 0.5 x 502.9 = 357.3 + 53.6 + 377.2 = 788.1 kN / m MEd = 31.6 + 0.0058 x 788.1 > 0.020 x 788.1 = 31.6 + 4.6 > 15.8 = 36.2 kNm / m or NEd = 1.0 x 214.6- 135 x 50.1 - 0 x 31.2- 1.5 x 0.5 x 502.9 = 214.6- 67.6- 0 -377.2 = -230.2 kN / m (tension) MEd = 31.6 + 0.0058 x 230.2 = 33.0 kNm / m

Consolidate c) into a) and b) to consider two load cases:

NEd = 1149.4 kN / m, MEd = 36.2 kN / m (out of plane) and NEd = -607.4 kN / m,
