8.2 Connections for buildings For multi-storey buildings the connections between the main structural elements may conveniently be classified as: Beam-to-beam connections Beam-to-column connections Column splices Column bases Bracing connections. Despite the different geometrical configurations and detailed structural requirements of the five different types, certain general functional requirements must always be addressed

8.2.1 Simple connections Simple connections are 国国 defined as joints between members that have not been 国 designed with the intention that they transmit significant moments. Beam-to-beam connection lt Floor decks in buildings are usually supported by means of grids of secondary beams and main girders simply connected to each other
