With the "Convert Area Loads on Openings to Line Loads" function, you can automatically take into account, for example, wind loads applied on windows or other loads applied on non‑bearing structures not represented in the model in openings. You can access this function via "Tools" → "Generate Loads" → "From Area Loads on Openings...."
The RF-/STEEL EC3 add‑on module allows for the fire protection design of structural steel components. The simplified analysis is performed by determining the steel temperature iteratively for a particular point of time.
In Part 1, the selection of the design criteria for dimensioning the reinforcement for the serviceability limit state design in RF‑CONCRETE Members and CONCRETE was explained. Now, we go into detail for the function "Find economical reinforcement for crack width design".
If you want to orient a nodal support to the member axes of the connecting member, the easiest way to do this is to use the "Pick Member and Import its Rotation" function.
If you want to model two intersecting surfaces, RFEM offers you the possibility to create the section line automatically. In the program, this function is referred to as intersection. When generating an intersection, the modeled surface is split into components. This has the advantage that the components can be taken into account in the determination of the internal forces, or deactivated.
In RFEM and RSTAB, it is possible to define nonlinear properties of member releases. In addition to the activity diagrams and force-deformation relationship, you also have the simple option of using signs or limit values of the internal forces as criteria for the effectiveness of the release. This way, you can specify which internal forces should be transferred at the member end.
To determine the distance between two nodes or the angle between two objects without using the dimensioning function, you can simply use the "Measure" option on the "Tools" menu. Here, you can also choose between various measure functions.
In the calculation parameters, you can set the number of member divisions for result diagrams. The effect of this setting option is shown in the following images.
In RFEM 5 and RSTAB 8, it is possible to assign nonlinearities to member hinges. In addition to the nonlinearities "Fixed if" and "Partial activity", you can select "Diagram". If you select the "Diagram" option, you have to specify the according settings for the activity of the member hinge. For the individual definition points, it is necessary to specify the abscissa and ordinate values (deformations or rotations and the according internal forces) that define the hinge.
You can assign comments to each element in RFEM and RSTAB (structure element, load element, and so on). This can help to improve the overview and documentation of structures, as the comments appear in the printout report and, for example, certain objects can be filtered and displayed using the "Select Special" function.
