Analyse ribbon
Command | Description |
---|---|
1st Order Linear | - Runs a linear static analysis. This analysis type is suitable for structures where secondary effects are negligible. Any nonlinear springs or nonlinear elements present are constrained to act linearly. Loadcases and Combinations to be considered in the analysis can be pre-selected. Nonlinearity Included:
See also: Run 1st order linear analysis |
1st Order Non-linear | - Runs a nonlinear analysis with loading applied in a single step. This analysis type is suitable for structures where secondary effects are negligible and nonlinear springs/elements are present. Loadcases and Combinations to be considered in the analysis can be pre-selected. Nonlinearity Included:
See also: Run a 1st order non-linear analysis |
1st Order Modal |
Runs an unstressed modal analysis to determine the structure's natural frequencies. The structure is assumed to be in an unstressed state and nonlinear elements are constrained to act linearly. Nonlinearity Included:
See also: Run a 1st order modal analysis |
2nd Order Linear | - Runs a 2-stage P-Delta analysis. This analysis type is suitable for structures where secondary effects are of comparable magnitude to primary effects. Any nonlinear springs or nonlinear elements present are constrained to act linearly. Loadcases and Combinations to be considered in the analysis can be pre-selected. Nonlinearity Included:
See also: Run a 2nd order linear analysis |
2nd Order Non-linear | - Runs a nonlinear analysis with loading applied in a single step. This analysis type is suitable for structures where secondary effects are of comparable magnitude to primary effects and nonlinear springs/elements are present. Loadcases and Combinations to be considered in the analysis can be pre-selected. Nonlinearity Included:
See also: Run a 2nd order non-linear analysis |
2nd Order Buckling | - Runs a linear buckling analysis to determine a structure's
susceptibility to buckling. The stressed state of the structure is determined from linear analysis; therefore nonlinear elements are constrained to act linearly. Loadcases and Combinations to be considered in the analysis can be pre-selected. Nonlinearity Included:
See also: Run a 2nd order buckling analysis |
Analyze All (Static) |
- Performs a full series of analyses that would be carried out as part of 'Design All (Static)' but with no design. Includes all relevant analyses. Analysis type (e.g. second-order non-linear) is the same as set in the design settings. See also: Run Analyze All (Static) |
3D only (Static) |
- Performs same analyses as 'Analyze All (Static)' but excludes chasedowns. This can save time during scheme design, for example while addressing overall stability, sway, drift, wind drift, etc. See also: Run 3D only (Static) |
1st Order RSA Seismic | - Runs Modal Response Spectrum Analysis to determine the peak response of the structure to earthquakes. Any nonlinear springs or nonlinear elements present are constrained to act linearly. For RSA Seismic Combinations, the peak responses are enveloped around the static results for 1st Order Linear Analysis. |
2nd Order RSA Seismic | - Runs Modal Response Spectrum Analysis to determine the peak response of the structure to earthquakes. Any nonlinear springs or nonlinear elements present are constrained to act linearly. For RSA Seismic Combinations, the peak responses are enveloped around the static results for 2nd Order Linear Analysis. |
Model & Results | - Displays the analysis model data in spreadsheets for review/editing. |
Wind Tunnel | - Displays the wind tunnel data tab, and wind model data in spreadsheets for running modal analysis and reviewing the results. |
Mesh Slabs | - Slabs are meshed automatically for FE Load Decomposition, FE Chasedown, and also if specified in the 3D Analysis. This command is only used if you need to mesh slabs manually. After the operation the slab mesh is automatically switched on in the scene content. |
