However, extra care in detailing during design and extra care in placement of the column reinforcement during construction is required. 3. column, concrete and steel reinforcement are shortened by the same amount due to their composite action. Figure 2: Spirally-reinforced column Composite Columns A composite column is a column made of structural steel shapes or pipes surrounded by or filled by concrete with or without longitudinal reinforcement, shown in Figure 3. The minimum dimension of column shall not be less than (a) 15 times the largest beam bar diameter of the longitudinal reinforcement in the beam passing through or anchoring into the column joint, and (b) 300 mm. Commentary 1.0 A small column width may lead to following two problems : (a) the moment capacity of column section is very low since GENERAL REQUIREMENTS TO BUILD A GOOD STAIR, 40+ Modern TV Unit Designs For Your Your Home, Beautiful Small House With Greenish Touch, 40+ Wooden Front Door Designs For Your Home, Difference Between One Way Slab And Two Way Slab, Top Civil Engineering Project Topics For Final Year Students.
