Problem

Design a 400 mm square column, having an effective length of 8 m in both directions, to withstand the design ultimate first order moments shown in Figures 5.7 and 5.8 combined with a design axial load of 2000 kN. The concrete strength class is C30/37 and the reinforcement has a characteristic strength of 460 N/mm2.

X = (8000/400) ยก12 = 69.3 in both directions Assume d'lh = 0.15

Figure 5.7 First order moments in z direction
Figure 5.8 First order moments in y direction
