The column section shown above is reinforced with equal number of 20 mm bars с 1. on each face. Using f'c = 21 MPa, long bar fy = 420 MPa, calculate the following: The distance of the neutral axis “c” (mm) from the extreme concrete compression fiber at balanced condition with bending about x-axis. A. 285 C. 335 D. 275 B. 320 2. 3. The compressive force on concrete compression area (kN) when section fails at balanced condition with bending about the x-axis. A. 1,780 KN B. 3,255 KN C. 2,094 kN D. 1,690 kN The internal force in the 2 bars at the middle when the section fails at balanced condition with bending about the x-axis. A. 11.71 kN B. 17.19 kN C. 10.81 kN D. 28.34 kN
