Composite Column with Concrete Filled Circular Hollow Section Subject to Axial Compression and Uniaxial Bending
This chapter demonstrates the design of a composite column subject to axial compressive load and bending moment. The concrete‐filled column consists of the circular hollow section filled with concrete. Second‐order effects are included in two ways, by using a first‐order analysis modified with appropriate amplification according to clause 6.7.3.4(5), EN 1994‐1‐1, and by using exact second‐order analysis. The confinement effects for a concrete‐filled circular tube can result in increasing the cross‐sectional plastic resistance. For long‐term loading the creep and shrinkage are taken into account in design by a reduced flexural stiffness of the composite cross‐section.In order to determine the resistance of the composite cross‐section to combined compression and uniaxial bending, it is necessary to produce an axial load – bending moment (N–M) interaction curve. The resistance of the column in combined compression and uniaxial bending was performed in accordance with clause 6.7.3.6, EN 1994‐1‐1.
