Semi-rigid floor-to-wall connections using side-framed lightweight steel structures: Concept development
September 15, 2020
This paper presents the development of side-framed lightweight steel (SFLS) structures featuring semi-rigid floor-to-wall connections. Initially, the effect of variation of connection rotational stiffness on the design of a two-story frame is investigated considering different construction methods. The results revealed a considerable effect of the connection rotational stiffness on the design of the joists and studs. A semi-rigid connection is then developed using validated finite element analyses. The developed SFLS system enables more efficient designs addressing the predominant limit states of the conventional designs with fewer and lighter flooring members and connections.
