Steps of the seismic analysis
Modal response spectrum based seismic analysis can be performed with the following steps in Consteel:
-
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
-
Seismic effect definition/Masses tab
- Definition of Standard or User defined response spectrum
- Definition of Seismic effect
- Setting the analysis method
-
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!
-
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
-
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.
