Question
In the case of a single-span beam with uniform load (M = q * l2/8), the moment graphic is not displayed as a parabola. The table result values are correct only at the maximum, but not at the other locations.Answer
The problem with the internal force graphic is due to the member divisions. In RSTAB, there are several divisions to consider.
1st Member divisions for result tables
The member divisions for result values can be created via "Insert" → "Model Data" → "Member Divisions." This division ensures that, for. For example, the internal forces of members can also be displayed at intermediate points in RSTAB Table 4.1. The graphical result display remains unchanged.
Figure 02 - member division
2nd Member divisions for graphical display
The divisions for the graphical result diagram and the extreme value determination can be viewed and influenced in the calculation parameters (pull-down menu "Calculation").
If you set the value for "Result Diagrams" to a larger value, the internal force graphic is displayed more finely.
To improve the graphic, it is therefore recommended to apply a finer member division.
