Using bolted connections for the construction, de-construction and reuse of lightweight exterior infill walls: Experimental study

Bolted connections ofer advantages in terms of disassembly and reusability, potentially replacing conventional connections like screws, welds, or chemical bonds. This research investigates the behaviour of bolted connections between lightweight exterior infll walls and beams of primary structural members that are conventionally connected using screws. Although previous studies have investigated bolted connections in diferent structural members, understanding of the behaviours of these specific connections remains limited. The connections between infll walls and steel beams primarily experience shear loads under serviceability conditions. Therefore, an experimental study was conducted to gain insight into their shear behaviour. The obtained experimental results were analysed using existing predictive equations from design standards that are used across European, North American and Oceanian countries, to identify the most suitable equations for designing such connections.
