| Abstract |
This study presents an experimental investigation on semi-rigid beam-to-column bolted connections utilizing austenitic stainless steel (STS316)
angles. The structural behavior of these connections was compared with that of connections using carbon steel (SS275) angles. The purpose
of this study is to evaluate the structural performance of stainless steel connections and assess their feasibility as an alternative to
conventional carbon steel connections. The experimental results provide an insight into the moment-rotation behavior of the connections,
emphasizing the influence of material properties on stiffness, strength, and ductility. The STS316 connections showed on average, 29% lower
initial stiffness and 21% lower yield moment compared to the SS275 connections. However, the yield rotation of the STS316 connections
was up to 1.16 times higher than that of the SS275 connections, indicating superior ductility. Additionally, at a rotation angle of 0.02 rad,
the moment strength of the STS316 connections was 5?7% lower than that of the SS275 connections. However, the moment at the onset of
bolt slip was 1.11 times higher than that of the SS275 connections. These findings confirm the applicability of stainless steel as a joint
material, highlighting the significant influence of strain hardening on the mechanical performance of stainless steel joints. The results suggest
that partial application of stainless steel in connections can enhance structural performance. |
