Bar stresses
The Bar stresses analysis result shows stresses in bar elements under the current loading or analysis conditions.
It allows you to evaluate normal and shear stresses in bars resulting from internal forces acting on the element cross-sections.
Bar stresses are available for several static analysis contexts.
- Load cases – stresses from individual load cases
- Moving load maximum – envelope of maximum stresses due to moving loads
- Moving load influence line / surface – influence results for bar stresses
- Construction stages – stresses during staged construction
- Load combinations – stresses from defined load combinations
- Maximum of load combinations – envelope of stresses from multiple combinations
- Maximum of load groups – envelope of stresses grouped by load groups
Result selection
Depending on the selected analysis context, additional selections are required to display Bar stresses. One or more of the following parameters may need to be selected from the result lists:
- load case type, such as ultimate or quasi-permanent
- load case or load combination
- stress component, for example normal or shear stress
- moving load, for moving load–based results
- construction stage
Only the selections relevant to the active analysis type are shown.
Result display
Bar stresses can be displayed using the following result display types:
- Graph – stresses shown as diagrams along bar elements
- Colour palette – stresses visualised as coloured fields along bars
For special minimum/maximum envelope results, like the σ x'(max/min), the stresses are displayed only as graphs.
Graph
Bar stresses shown as graph on bars.
As an example of graph display, here is the special σ x'(max/min) result that only shows as graph, but shows both the minimum and maximum portion of the graph on the same image.
Colour palette
Bar stresses visualised as coloured fields.
