Bolted at intersection with end plates, possibly with a stiffener plate behind – where beams are different depths these can be flush top or bottom to suit your site requirements.

Simple connections are nominally pinned connections that are assumed to transmit end shear only and to have negligible resistance to rotation. Therefore do not transfer significant moments at the ultimate limit state. This definition underlies the design of multi-storey braced frames in the UK designed as ‘simple construction’, in which the beams are designed as simply-supported and the columns are designed for axial load and the small moments induced by the end reactions from the beams. Stability is provided to the frame by bracing or by the concrete core.
