Filled Rec. HSS Composite Columns

This is a numerical example for calculating the available compressive capacity of a filled rectangular HSS composite section.

It should be noted that due to the differences in resistance and safety factors between composite and non-composite column provisions, it is possible to calculate a lower available compressive strength for a composite column than one would calculate for the corresponding bare steel section. However, in accordance with AISC Specification Section I2.2b, the available compressive strength need not be less than that calculated for the bare steel member in accordance with Chapter E. This point is detailed in the below example.

In the next Article, the load transferring between structural steel and the concrete shall be explained.
