Abstract

Reseach results have shown that columns in low-to-medium rise special two-story X-braced frames should be designed based on the capacity of the braces because of high column demands. Composite columns, either encased of filled, can be an economical solution to deal with the additional axial load capacity over that available with steel columns alone. Forces must be transferred between steel and concrete in composite columns so that dissimilar materials can achieve a state of equilibrium and act in a composite manner. With the new 2010 AISC Specification for Structural Steel Buildings, the provisions for force transfer have been greatly expanded in a new section to address the lack of clarity in previous Specification. The concept of load introduction length (AISC Specification I6.4) will be applied in the design the composite columns in low-to-medium rise special two-story X-braced frames with particular emphasis on the headed stud anchor provisions as they relate to load transfer. The clearer guidance in addressing component behaviour, design techniques, and proper detailing considerations in the 2010 AISC Specification will be followed.
