A concrete circular column with a radius of 350mm has f'c=25 MPa and is braced against sidesway. The column is assumed to be pinned on both ends with an unsupported length is 6.1meters. The column is subjected to the following service loads: Axial Dead Load =350 kN Axial Live Load=480 kN Moment due to Dead Load on the top of the column = 125 kN-m Moment due to Dead Load on the bottom of the column = 60 kN-m Moment due to Live Load on the top of the column = 122 kN-m Moment due to Live Load on the bottom of the column = 75 kN-m. If the moments bent the column in a singular curve, determine the following: 1. Critical Load on the column, kN 2. Moment

Question
A concrete circular column with a radius of 350mm has f'c=25 MPa and is braced against sidesway. The column is assumed to be pinned on both ends with an unsupported length is 6.1meters. The column is subjected to the following service loads:
Axial Dead Load =350 kN
Axial Live Load=480 kN
Moment due to Dead Load on the top of the column = 125 kN-m
Moment due to Dead Load on the bottom of the column = 60 kN-m
Moment due to Live Load on the top of the column = 122 kN-m
Moment due to Live Load on the bottom of the column = 75 kN-m.
If the moments bent the column in a singular curve, determine the following:
1. Critical Load on the column, kN
2. Moment Magnifying factor
3. Design Moment of the column, kN-m
