All calculation diagrams that you have defined are listed in the Calculation Diagrams tab of the 'Overview' table category. Special chart types are available for pushover analysis.
You can use the
button in the 'Options' column to check the parameters of a calculation diagram. The dialog Edit calculation diagram appears. Alternatively, use the 'Calculation Diagrams' category in the Data Navigator to open this dialog box.
Convergence Diagram
The 'convergence diagram' diagram type allows you to check how the maximum deformation evolves in the course of the pushover analysis.
This graphic corresponds to the calculation diagram that was displayed during the pushover analysis in the window Calculation Progress is displayed.
Force-deformation diagram
The 'Basis' diagram type offers the possibility of displaying a force-deformation diagram of the pushover analysis.
In the 'Source' section, select the Pushover Analysis analysis type. For example, if you compare the displacement of the top node with the sum of the horizontal support forces, you get the capacity curve. This allows you to assess the "deformation capacity" of the structure.
Pushover Diagram (ADRS)
The diagram type 'Pushover ADRS' enables the results of the pushover analysis to be evaluated in a special calculation diagram. Here you can visualize the action and the structural behavior in the form of a representation as ADRS ( Acceleration Displacement Response Spectrum ).
The 'horizontal axis' is fixedly related to the value d * of the structural displacement. For the ' vertical axis ', the following result types are available:
- Range of requirements: Acceleration of the structure due to horizontal forces (response spectrum)
- Capacity spectrum, bilinear: Idealized capacity curve of the building according to the standard
- Capacity range: Capacity curve with actual deformation behavior of the building
- Range of requirements | Capacity spectrum, bilinear: Superposition of demand spectrum and idealized capacity spectrum
- Range of requirements | Capacity spectrum, bilinear | Capacity range: Superposition of the range of requirements and the two capacity range variants
The target shift dt * results from the superposition of the curves.
