Eqn A.3.2 where h = height of frame in metres = 4 x 3.5 = 14 m

F = sum of all vertical loads taking y = 1

= 4 x 1900 + 2 x 2100 + 4 x 3300 + 2 x 1200 = 27400 kN E I = sum of the stiffnesses of the bracing elements.

Table 3.2

cm c

= 2024960 x 109 Nmm2

Hence

27400 x 103

cm c

E I J 2024960 x 109

Note:

Since the height of the building is stated to be in metres, it seems reasonable to assume that m units should be used for the other factors, though this is not stated in EC2.

Hence
