Riveted Structures

Riveted Structures

 

metal structures whose elements are joined by rivets. Contemporary metal structures are fabricated predominantly by welding; the fact that rivet holes weaken the cross section of riveted structures by 15–20 percent, as well as the labor-intensiveness of such structures, has made riveted structures less advantageous than welded structures in many cases. However, riveted structures are more reliable under low-temperature conditions, in which the stress concentration that promotes brittle failure and develops around rivet holes is substantially less than the concentration of stresses in weld seams. Therefore, riveted structures are frequently preferred for construction in northern areas.

Riveted structures are also used in bridge construction (predominantly for railroad bridges) and in the construction of industrial buildings that carry large loads (for example, for beams supporting a crane), where the possibility of metal failure under a cyclic load is particularly dangerous or where the fabrication of a high-strength, built-up cross section by welding presents considerable technological difficulties.

Experimental evidences of a consistent amount of riveted structures have shown that the great majority of fatigue failures are generally related to the connected material and not to the rivet itself (Kulak 2000); even if in case of missing rivets the possible collapse of a bridge is evidence that also rivets could play an important role in fatigue failure.
