Abstract |
As buildings become taller and larger, the structural safety of envelope systems has increased the demand for cast-in anchor channels owing to their installation flexibility and superior performance. Due to the lack of domestic standards in South Korea, European specifications (EAD and EN) are currently utilized. This study evaluates the structural reliability of a domestically developed hot-rolled anchor channel system to establish characteristic resistance values for structural design. Following the EAD 330008-04-0601 protocol, static tension and shear tests were conducted. The results confirmed robust structural integrity under ultimate loads without sudden strength degradation, facilitated by a stable load transfer mechanism through the bolt-lip-profile-anchor sequence. Furthermore, coefficients of variation (COV) below 5 % across all series demonstrated high quality, with characteristic strengths closely approximating mean failure loads. This enables more economical design by minimizing the required strength reduction factors. These findings provide a standardized engineering foundation for the development of future domestic design standards. Subsequent research on seismic and fatigue performance is expected to further enhance the structural safety of domestic building envelope systems.
