Design axial load ground st floor NEd

Qk1 = leading variable action (subject to reduction factor aA or an)

Qki = accompanying action (subject to aA or an)

<Table 2.5, BS EN 1990: A1.2.2 & NA> <BS EN 1991-1-1, 6.3.1.2 (10), 6.3.1.2 (11), & NA>

an = 1.1 - n / 10 for 1 < n < 5 = 0.6 for 5 < n < 10 and = 0.5 for n > 10 where n = number of storeys supported **

an = 0.6 for 8 storeys supported .'. as an < aA, use an = 0.6 Assuming the variable action of the roof is an independent variable action: NEd = 1.35 x 5553.6 + 1.5 x (2279.5 - 42.0) x 0.6 + 0.7 x 1.5 x 42.0 = 1.35 x 5553.6 + 1.5 x 2237.5 + 0.7 x 1.5 x 42.0 = 7497.4 + 2013.8 + 44.1 = 9555.3 kN

NEd = ZYoGk + YQQk1 + VoYaQ, assuming the variable action of the roof is an independent variable action: = 0.925 x 1.35 x 5553.6 + 1.5 x (2279.5 - 42.0) x 0.6 + 0.7 x 1.5 x 42.0 = 1.25 x 5553.6 + 1.5 x 2237.5 x 0.6 + 0.7 x 1.5 x 42.0 = 6942.1 + 2013.8+ 44.1 = 9000.0 kN Greener Homes for You
