ICONS
A c = Gross cross-section area of the column
E = Earthquake effect
Q = Live load effect
G = Constant load effect
N dm = Considering the live load reduction coefficients defined in TS 498, G and Q are vertical loads and E earthquake effects. Maximum of axial compressive forces calculated under joint effect G + Q + E
f ck = Characteristic cylinder compressive strength of concrete
7.3.1.1 - The smallest cross section dimension of rectangular columns shall not be less than 300 mm and circular columns diameter shall not be less than 350 mm.
7.3.1.2 - The gross cross-section area of the column, N dm , taking into account the live load reduction coefficients defined in TS 498, the joint effect of vertical loads G and Q and E earthquake effect is the maximum of axial pressure forces calculated under G + Q + E. larger, it will satisfy the condition A c ≥ N dm /(0.40 f ck ).
