摘要

The plastic deformation behaviour of embedded-type column bases was experimentally examined. The primary parameters were width-to-thickness ratio and axial load ratio, and results showed significant strength deterioration induced by local buckling that was largely affected by the test parameters. Analytical models of the test specimens were developed. The developed models were applied for nonlinear dynamic analysis of low- and mid-rise steel moment frames. The analysis results showed the importance of considering deterioration behaviour of column bases as it significantly affected the response and the collapse limit. Large dependency of the collapse limit on the width-to-thickness ratio of the column in addition to the strength itself is also noted from the analysis.
