Shear strength investigation of connections between RC and strengthened steel frames
https://orcid.org/http://orcid.org/0000-0001-6012-1718
A numerical analysis model should consider the indirect connection’s shear strength to evaluate buildings’ seismically strengthened effect by embedded and perimeter steel moment frames with the indirect connection. The seismic design code for the Korean school facilities does not support the particular indirect connection’s design information, recommends to secure through the experiment. This paper investigates the shear strength of bolted indirect connections of the steel retrofit method per the experimental results. The bolted indirect connection for the embedded steel retrofit method dissipated most indirect connection energy, excluding the connection steel plate and post-installed anchors as flexural behavior. Regardless of the lack of concrete shear strength due to the post-installed anchors, it was not observed the cracks in the column. In contrast, the bolted indirect connection of the perimeter steel retrofit method was confirmed as the only vertical cracks due to the post-installed anchors in the column and the indirect connection. This indirect connection is that the post-installed anchors resisted the shear force as shear behavior. According to these experimental results, the shear-resistant capacity of bolted indirect connections of the embedded and perimeter steel retrofit methods was proposed.
