Abstract: Observed damage and analytic studies indicate that earthquakes may cause destructive pressure surges in liquid-filled piping. Most studies have concerned buried piping that could be assumed to ...

Abstract: Water hammer pressure in piping is modified by the consequent motion of the piping. In general, accurate estimates of dynamic pressure and pipe displacement must account for this interaction. ...

Abstract: Transient pressure in piped liquid is a function of structural restraint at elbows. If supported rigidly, an elbow causes no appreciable alteration of the pressure transient generated by rapid ...

Abstract: Pipe vibrations can be induced by internal liquid pulsations which propagate throughout the piping system and create unbalanced oscillatory pressure forces at locations where either flow area or ...

Abstract: Since liquid-filled piping systems are composed of slender elements, their transient behavior can be described as one-dimensional wave phenomena. Seven wave components are identified: coupled axial ...

Abstract: The motions of liquid-filled pipe reaches in which long wavelength assumptions are valid can be described by Poisson-coupled axial stress waves in the pipe and in the liquid column, and in ...

Abstract: A four equation model of axial wave propagation with Poisson coupling which includes viscous damping to account for structural energy dissipation is evaluated. Comparison of the predictions with ...

Abstract: The traditional approach to designing a piping system subject to internal dynamic pressure is to restrain the piping as much as possible, and the approximation made in the analysis is to ...
