Highlights

  • Calculation of the characteristic frequencies and modes of the member construction.
  • Automatic calculation of the self-weight of the structure.
  • Other weights can be entered as local or distributed loads or converted from earlier static calculations into dynamic weight.
  • The user sets the desired number of characteristic values.
  • For each characteristic value, the characteristic mode will be calculated with the subspace iteration method.
  • The results can be represented both numerically and graphically.

Eigen frequencies can be required to verify comfort criteria for buildings, to analyse wind-induced resonance for bridges, to check requirements for sensitive equipment....

  • Input of dynamic masses
  • Selection of desired number of characteristic values
  • Review of numerical and graphical results: frequency values, mass participation factors and modal shapes

Input of masses

  • User input of nodal masses or linear distributed masses
  • Automatic generation of masses from the self-weight
  • Generation of masses from selected static load cases (converts downward vertical loads into masses)
  • Regeneration of masses after modification of selected load cases

Output of results

  • Table output of eigen frequencies for each calculated natural mode
  • Table output of mass participation factors according to each global direction (X, Y and Z).
  • Graphical display of animated eigenmode shapes

Eigen frequencies can be required to verify comfort criteria for buildings, to analyse wind-induced resonance for bridges, to check requirements for sensitive equipment.... You can apply this analysis type to structures containing surface elements (plates and shells) by performing a few steps:

  • Input of dynamic masses
  • Selection of desired number of characteristic values
  • Review of numerical and graphical results: frequency values, mass participation factors and modal shapes
