A hollow concrete column has a rectangular cross-section with an external breadth of 300mm and an external depth of 600mm.The internal breadth is 240mm and the internal depth is 520mm.The compressive resistance of the concrete is 200 N/mm2. If the effective height of the concrete column is 2.8m, calculate:
(i) The least radius of gyration
(ii) The slenderness ratio
(iii) The maximum axial load that the column can carry
Additional information
The problem related to Physics and it discusses about calculating least radius of gyration, slenderness ratio and maximum axial load that a hollow concrete column can carry.
