These classes of long span steel framing options along with their applications and various configurations are provided in Table-1. Table-1: Long span steel Types of Steel Beam Connections and their DetailsThere are various types of steel beam connections used in structures. Steel beam connections are categorized into two groups namely framed and seated connections. In the framed steel beam connections, the beam is connected to the supporting steel element through fittings whereas in case of seated connections, the beam is positioned on seat similar to the case where beam is placed on

Ready for quick and efficient assembly Since all the main components of prefab steel frame building are pre-cut, pre-drilled and pre-welded in the manufacturers factory, and then set up at the desired location, it has short construction period.Portal frames - SteelConstruction.infoThe major connections in a portal frame are the eaves and apex connections, which are both moment-resisting. The eaves connection in particular must generally carry a very large bending moment. Both the eaves and apex connections are likely to experience reversal in certain combinations of actions and this can be an important design case. For economy, connections should be arranged to minimise
