Beam-to-column connections As for beam-to-beam connections,the bolts and the welds should be able to resist B the beam reactions and the relevant moment due to the eccentricity of the force to the centreline of the connecting material.Since this eccentricity C is relatively small the column bending moment for such a connection is much smaller than from a moment connection

Bracing connections Connections within the bracing system or between the bracing system and the main framing have to transfer forces between a number of differently oriented members.Since the triangulated bracing arrangement will have been designed on the basis that each member carries only axial forces,the design requirement for the bracing connections is essentially the transfer of direct forces between a number of differently oriented members.

Column bases A column base connection always consists of a plate welded to the foot of the column and bolted down to the (aj b (c) foundations. A second,usually rather thicker,steel plate is normally incorporated into the top of the foundation.It helps both to locate the foot of the column accurately and in spreading the load into the weaker (concrete or masonry)foundation material. Base plate connections in simple construction are generally modeled as pins,and designed to transfer either concentric force or a combination of axial and shear force

8.2.2 Moment Connections for Continuous Framing Moment connections:to transmit shear force,axial force moment.'Continuous'framing implies connections which are sufficiently 'performing'(in terms of stiffness and/or strength). An elastically continuous frame could incorporate connections which are Rigid and Partial Strength. Similarly,a plastically continuous frame could incorporate connections which are Full Strength and Semi-Rigid(though it might be necessary to take account of connection flexibility when serviceability and stability are under consideration)
