Semi Rigid Behaviour of Single Web Angle Connection
Connections constitute a small percentage of the weight of a structure, but they have a relatively high labor
content and hence represent a substantial percentage of total framing. Connection deformation is sometimes responsible for a
substantial proportion of overall deflection of structure and it often has a significant bearing on the internal force
distribution. Design of steel frames are carried out with the assumption that the beams-to-column connections are either
rigid or pinned. Steel frames can be designed economically by incorporating the semi-rigid behaviour of the connection.
Authors account the semi-rigid behaviour of single web angle connection in analysis by modifying the stiffness matrix and
also proposed a partial moment release factor to simulate the semi-rigid behaviour in Staad pro.
