Part 1: Architect’s Guide 1 - 26 Mineral wool layers supporting the plasterboard. The space between the beams under the floor can be used for service integration (ducts). Figure 4.19 Composite slab with thermal insulation 4.4 Connections 4.4.1 General Steel construction is based on a simple principle, involving the assembly of elements, such as columns, beams, bracing members, tie members. The components of the building envelope – floors and partitions – are then connected to the principal members. The main function of a connection is to transfer internal forces between the members, in a way that is consistent with the design assumptions – pinned or continuous connection. When the connections are visible, their aesthetic quality can emphasise the structural behaviour and contribute to the architectural value of the building 4.4.2 Types of connections There are many types of connections for structural members. The principal types commonly used in multi-storey buildings are: Nominally pinned connections (beam-to-beam and beam-to-column) Moment connections (beam-to-column) for continuous frames Connections of bracing members Column bases. Figure 4.20 shows three types of beam-to-column connections. These connections can be considered as pinned. This type of connection is mainly designed to transfer a shear force and a small axial force.
