Strength of Square CFT Stub Columns with Slender Sections

Abstract:

This paper presents an investigation of ultimate strength of square CFT stub columns with slender sections. The definition of square CFT stub columns with slender sections is discussed and a new strength model is proposed. Experimental results of 31 axially loaded square CFT stub columns published in the literature are then used to verify the proposed strength model. Results show that the proposed strength model provides a direct, compact, and efficient representation of the ultimate strength of square CFT stub columns with slender sections.
