Typically, using such steel frame member sectional member, for ease of processing. However, in a multi-storey industrial building for a large area of the door frame in the industry, often based on the member section by changing the use of force along the length of the member variable cross-section of members to save timber. In the multi-rise steel buildings, floors and more in the form of in-situ concrete slab for the use of bearer role in the framework of the system can be set up on the pegs beams, steel beams and concrete slabs so that work together to form a concrete steel composite beam.
According to the force deformation characteristics, Steel Frame connection can be divided into three categories.
(l) a rigid connection between the beams no relative rotation, the connection can withstand bending moments.
(2) hinged connection between the beams relative rotation, the connection can not withstand bending moments Room
(3) semi-rigid connections beams relative rotation, connection can withstand bending moments.
A typical structure in the form of various types of steel frame beams connected, which is semi-rigid frame steel frame system connecting peculiar.
