Strength and dynamic characteristics of mechanically jointed cast iron water pipelines

Kratky, R.G. / Salvadori, M.G.

The report expands on the earlier Interim Grant Report IR-3, July 1977. Elastic and dynamic characteristics of both mechanical joints with rubber gaskets and cast-iron pipes are discussed. The main characteristics for pipe failure are the ultimate tension force and the ultimate bending moment. Practical observations confirm that other modes of failure seldom occur, although some compression failures have occurred. Bolt failure, ultimate gasket friction, the longitudinal elastic constant of gasket, longitudinal periods of pipe due to gasket elasticity, longitudinal periods of pipe due to pipe elasticity, the rotational constant of gasket, periods of rotational motion due to gasket, and periods of vibration for vertical anti-symmetrical rotational modes of continuous elastic pipes are topics discussed. Some calculations are carried out as axemples. (Buehn)
