Many methods can be used to assemble large mechanical structures. Using rivets is one of these methods. Rivets are lighter than bolts and allows for efficient assembly. The cylindrical structure has a discontinuous rivet assembled region. So concentration load operates in the edge of discontinuous assembled region. This paper evaluates the force placed upon rivets used to assemble cylindrical structures and strength of structures assembled with rivets. Plastic deformation of rivets occurs at 4 kN and rivets are destroyed at 7 kN. However, rivets are designed to transfer load to neighboring rivets when they are overloaded. Structural test were accomplished using tension and bending load condition. The structural tests showed that plastic deformation first occurs in the fastening where the rivet meets the outside of the cylinder and a number of rivets exhibited this type of deformation. The secondary phase of deformation occurs in the fastening where the rivet meets the inside of the cylinder. Despite the plastic deformation, the structural tests showed that the rivets succeeded in redistributing load to neighboring rivets and as a result, no rivets were destroyed.
