Applications where time history dynamic analysis can be beneficial are analysis of waterhammer or steamhammer fluid transient loads, analysis of piping pulsations loads from reciprocating equipment (sinusoidal time history loading), seismic loadsground motion accelerations, unbalanced vibrating machinery loads (sinusoidal time history), and relief valve openings. Use of approximate static load factors to account for dynamic loading effects may be a questionable approach that needs to be investigated.
