| Settings | Opens the Analysis Settings dialog. See: Analysis settings |
| 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: - Geometric: No - Material: No |
| 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: - Geometric: No - Material: Yes |
| 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: - Geometric: No - Material: No |
| 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: - Geometric: Yes - Material: No |
| 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: - Geometric: Yes - Material: Yes |
| 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: - Geometric: Yes - Material: No |
Staged Construction 1st Order Linear |
Runs 1st order staged construction 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: - Geometric: No - Material: No |
Staged Construction 1st Order Non-linear |
Runs a nonlinear staged construction analysis. 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: - Geometric: No - Material: Yes |
Staged Construction 2nd Order Linear |
Runs a 2nd order linear staged construction 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: - Geometric: Yes - Material: No |
Staged Construction 2nd Order Non-linear |
Runs a 2nd order linear staged construction analysis. 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: - Geometric: Yes - Material: Yes |
| 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. |
| 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: 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. |
| Calculate | Calculates center of mass and rigidity for diaphragms and floors. A modal mass combination needs to be defined to request this type of analysis. |
| Show Results | If you have defined more than one modal mass combination, you can click Show Results to cycle through the center of mass and rigidity results for the second, and each additional modal mass combination. |
