Columns and Struts - Special types of strut - Steel Structures

The design of two types of strut requires that certain additional points be considered:

(1) built-up sections or compound struts (Fig. 15.13), for which the behaviour of the individual components must be taken into account

(2) angles, channels and tees (Fig. 15.14), for which the eccentricity of loading produced by normal forms of end connection must be acknowledged.

In both cases, however, it will often be possible to design this more complex type of member as an equivalent single axially-loaded strut.
