dc.description.abstract	The hybrid systems of steel frames can offer more flexibility and enhance the seismic performance of mid-rise structures. The cold-formed steel (CFS) and hot-rolled steel (HRS) wall system is one such hybrid solution to achieve desired seismic performance level. This study focuses on the numerical analysis of curved steel dampers in the hybrid wall panel (HWP) consisting of cold-formed and hot-rolled squared hollow section (SHS) frames to improve energy dissipation, stiffness, and frame strength during cyclic loading. We evaluated several combinations of damper thicknesses (10 and 13 mm), depths (30, 40, and 50 mm), and angles (30°,45°,55°,60°,65°,and75°) to determine the most efficient damper geometry on seismic performance of the HWP frame. The results show that the energy dissipation, frame strength, and elastic stiffness are optimal when using (a) a 75° damper with 10 mm thickness and 40 mm depth or (b) a 55° damper with 13 mm thickness and 40 mm depth at the top of the hot-rolled section.

Abstract:

The hybrid systems of steel frames can offer more flexibility and enhance the seismic performance of mid-rise structures. The cold-formed steel (CFS) and hot-rolled steel (HRS) wall system is one such hybrid solution to achieve desired seismic performance level. This study focuses on the numerical analysis of curved steel dampers in the hybrid wall panel (HWP) consisting of cold-formed and hot-rolled squared hollow section (SHS) frames to improve energy dissipation, stiffness, and frame strength during cyclic loading. We evaluated several combinations of damper thicknesses (10 and 13 mm), depths (30, 40, and 50 mm), and angles (30°,45°,55°,60°,65°,and75°) to determine the most efficient damper geometry on seismic performance of the HWP frame. The results show that the energy dissipation, frame strength, and elastic stiffness are optimal when using (a) a 75° damper with 10 mm thickness and 40 mm depth or (b) a 55° damper with 13 mm thickness and 40 mm depth at the top of the hot-rolled section.
