Question: For the T - shape column shown in the figure below concrete cover to centroid of bars is 7 0 mm . Material strengths are

For the T-shape column shown in the figure below concrete cover to centroid of bars is 70 mm . Material strengths are f'c=20MPa and fy =275MPa. The longitudinal bars consist of 4-20mm diameter bars in the flange and 3-32 mm diameter bars in the web as shown. Neglect the area of concrete displaced by the steel reinforcements.
Determine the pure axial load capacity of the column in kN.
