The Modeland and Lateral Drift Stiffness of Steel Frame Column There are about three manners of the general beam-column connections for the engineering design of steel structures to be choosed,i.e.,(1)Weld connection shown in Fig. 1(a), (2)High strength bolted connection shown in Fig. 2, (3)Welded and bolted hybrid connection shown in Fig. 1(b).
In the usual engineering design of steel frame structure, beam-column connection is assumed either as a hinged connection, or as a rigid connection.
