Part of a two story building is shown in the figure in which a concerte column and a steel column are used in the first and second floor. The compressive force on the roof of the second floor is PC = 400 kN. The compressive force on the first floor is PB = 310 kN. The steel [Esteel = 200 GPa] column is a wide angle steel shape that has a cross section area of A2 = 1850 mm2. The concrete [Econcrete = 30 GPa] column has a circular section with a diameter of d = 530 mm.[L1 = 4.8 m, L2 = 5.8 m] What is the displacement of the column at B?in mm What is the displacement of the column at C?
