How will the dynamic masses be defined for an elevated water tank?</p> <p>I have modelled an elevated intze tank where the container is modeled using plates. The loads defined are - selfweight and pressures (hydrostatic and hydrodynamic) which act on the wall and base of the container. These (trapezoidal) pressures act along the local z axis of the plates. So while defining the&nbsp;dynamic masses for the time history load case how should the pressures be defined?</p><div style="clear:both;"></div>
