Select function Supports >Resultant of reactions.
Select the supports for the display of results.
Refresh the screen
Note: Until version 16.1. the selection could be made only by selecting separate supports. In post-processing environment of version 17 the resultant on selections will be displayed also when supported members are selected. Therefore it is possible to view reactions and resultants of reactions even with hidden supports only by making selection of entities that contain supports on their structural nodes or edges.
Values
Specifies the values, i.e. the components, which are displayed.
Either one or multiple components can be displayed at a time.
Extreme
Specifies the position on diagrams where numerical values are attached.
Possible options are: No, Node, Global
Rotated supports
Selects the type of supports.
Separate members
From version 17.0. there is possibility to use new post-processing environment for displaying results. The new post-processing environment could be enabled in the project dialogue. When using this post-processing environment a Separate members parameter is available. This allows the user to display resultant of reactions for separate nodal and linear supports at the same time. With this option disabled, the global resultant is calculated and displayed.
When the resultant is displayed for a linear support and if the selected linear support intersects another linear support, one must be aware of the following.
If several linear supports meet in one point or if they intersect each other, the resultant calculated for one of the supports takes into account also the results from other supports. As a result, if you display in turns the resultants for individual supports, the sum of these resultants will not be equal to the resultant calculated for all the supports selected simultaneously.
Let us assume a structure whose one part is supported by three linear supports that all meet in one point of intersection (red support A, blue support B and green support C).
Let us define some load (the exact size and distribution is not important as the example is just illustrative). That load produces the following resultants in individual supports (i.e. when these supports are selected separately):
red A = 111.1 kN
blue B = 60.1 kN
green C = 51.9 kN
The sum of these three resultants is 223.1 kN. When, however, all the three supports are selected at the same time, the total resultant is 189.2 kN.
The reason is that the resultants in individual supports take into account also the results from finite elements located in the two remaining supports (for example elements e2 and e3 if we evaluate the resultant in the support with element e1 in the picture below).
Note: Resultant of reactions cannot be displayed in case there is a surface support in the project.
