Design of Joints:

At joins while more than one member meet, the members are connected either by rivets or welds, through a common gusset plate whose thickness is more than the thickness of any connected member.

The joints are made such that the centroidal axes of the members meet at one point, to avoid eccentricity of connection. The joints are designed to resist the forces acting on the members and are designed according to the principles laid down in Unit 4 (Riveted and Welded Joints). The minimum nominal diameter of rivets should be 16 mm and the gusset plates should not be less than 6 mm thick.
