Single plate connections for steel beams

Single plate connections for steel beams, connected by high strength bolts to the beam web and welded to the column, were investigated to determine their, behaviour. Tests were performed on the connections in the absence and in the presence of shear, and shear was found not to affect the rigidity of the connections. Varying the gauge distance, the weld size, the pitch and the number of bolts in the test specimens, showed that only the pitch and the number of bolts influenced the rigidity of the connections. An increase in the pitch and the number of bolts causes an increase in the rigidity of the connections. In all cases the major slip value was greater than the usually assumed value. Under the action of pure moment the centre of rotation was found to be slightly above the centroid of the connection, whereas under the action of moment and shear the centre of rotation was slightly below the centroid of the connection. The maximum moment developed by the connections varied from 45 kip-inches for the two-bolt connection, to 355 kip-inches for the six-bolt connection.Applied Science, Faculty ofCivil Engineering, Department ofGraduat
