Steps of the seismic analysis

Modal response spectrum based seismic analysis can be performed with the following steps in Consteel:

  1. Definition of modal loads/Mass tab

    • Definition of mass cases and mass groups
    • Mass defintion manually on the structure, or by converting existing load cases
    • Mass combination definitions
  2. Seismic effect definition/Masses tab

    • Definition of Standard or User defined response spectrum
    • Definition of Seismic effect
    • Setting the analysis method
  3. Seismic loadgroup and load combination definition / Loads tab

    • Seismic loadgroup and loadcase creation
    • Assignment of seismic effect to seismic loadcase
    • Definition of considered shapes for the analysis – Only in the case of Selected modes, linear summation analysis method!
  4. Analysis / Analysis tab

    • Setting the statical calculation parameters; For the comparision of available analysis types, please check at the Analysis types chapter.
    • Setting the parameters for Dynamic calculations
  5. Design / Global checks and Member checks tab

    • For the available design checks, please go to the comparision of different types at the Standard design chapter.
