| Summary: | 碩士 === 國立中興大學 === 土木工程學系所 === 107 === As the section of steel unequal angles is asymmetric, unequal angles are often used as second members. When single angles under eccentric load, the mechanical behavior is complicated due to the section is asymmetric. For most structural engineers, the design of an eccentrically loaded unequal angle was considered to be a formidable task prior to the publication of the 2005 AISC Specification for structural steel buildings.
This study intends to use the AISC (2005, 2010 and 2016) formulas to deal with unequal angles. Compare AISC 2016 with previous versions. The provided examples are furnished to indicate
the analysis and design of the basic concepts of unequal angles.
This study explores the difference of Bathon tests and AISC results. Calculate the values which eccentric load applied at point according to AISC (2005, 2010 and 2016), and compare with
Bathon test results.
Analysis are made between a variety of methods of the unequal angles. It was found that the AISC design experimental values are significantly lower than the experimental values, which means the result is in line with industry expectations.
