To ensure that the cross-sections are recognized when directly importing girders and columns in REVIT, a corresponding family must be available for these components in the REVIT project.
If this is not the case, you can import a suitable family into your project during the import process. The interface then independently recognizes all other cross-sections and creates the corresponding cross-sections within the family.Figure 01 does not show a 480/520 (mm) timber column. After importing the correct family type, this cross-section and all other cross-sections of the same type are recognized and the import process is successfully completed.
If two members are hinged to each other, the corresponding release must be assigned to only one of these members.
If there are three members, which are all hinged, two of the three members will have the corresponding release.
Generally, a nodal point with a completely pinned design with an arbitrary number of member ends receives a total of one member hinge less than the existing number of member ends:
Number of member ends: n
Number of Member Hinges for Completely Hinged Connectors: n-1
Bei weniger als n-1 Stabendgelenken sind die jeweiligen Stabenden ohne Gelenk biegesteif miteinander verbunden.
Bild 1 zeigt drei Varianten eines Hauptträgers, an welchen ein Nebenträger anschließt:
Wird ein Stabendgelenk zuviel angesetzt, so kann es zum Abbruch der Berechnung aufgrund von Instabilität kommen. Demnach ist die oben beschriebene Regel zu beachten.
- Vollständig biegesteife Verbindung - kein Stabendgelenk
- Teilweise gelenkige Verbindung: Der Nebenträger schließt gelenkig an den durchlaufend biegesteifen Hauptträger an - ein Stabendgelenk
- Vollständig gelenkige Verbindung: Alle drei Stäbe schließen gelenkig aneinander an - zwei Stabendgelenke
AnswerWith the model check, members that cross each other but do not have a common node at the point of intersection can be found (see Figure 1). To check the model, select Tools -> Model check -> Opening or closing intersecting members.
The results are shown in the "Groups of Crossing Not Connected Members" dialog section. The crossing members are listed in groups; the current group is represented by a
The "What is to be done with" dialog section controls how the crossing members are handled. The "Connect members" option is suitable for actual transfer options for internal forces, but not for For example, for usual diagonal crossings with tension members.
Alternatively, it is also possible to use the model check to display the member pairs as an Excel list or to create visibilities. The visibilities created in this way can be quickly used to find and delete relevant members in the model.
AnswerWith the national annex ÖNORM B 1991-1-3: 2018-12, Austria has redrafted the width of the tolerance zones textually.
 In the third paragraph under the heading "Annex B", the standard accordingly states that within 2.5 km on both sides of the zone boundary, the characteristic value s k is the average of the affected zones. In the area of Vienna, we can assume a 250 m per side. This results in a tolerance zone width of 2 x 2.5 km = 5 km inland and of 2 x 250 m = 500 m in Vienna.
AnswerThis is possible. For this purpose, we select the temperature in the member load and display a random distribution over the depth of the cross-section.
AnswerYou can either define the nodal support or the intermediate restraint in RF- / STEEL EC3.If you already have nodes in your actual RFEM or RSTAB model, we recommend directly entering the nodal support in the 1.7 dialog box, because you can select the nodes directly in the model. See Figure 01.If you want to consider intermediate storage at a point in a horizontal beam where you do not have a node available in your actual system, you can use the intermediate support and select the intermediate support (for example Preload (lateral / torsional restraint)). See Figure 02.
AnswerTo do this, open the "General Data" dialog box of the current model. To do this, right-click the model description in the Data navigator. See Figure 01.Alternatively, you can open the "General Data" dialog box with the "Edit" menu. See Figure 02.In the "General Data" dialog box, you can select the standard according to which the combinatorics is to be carried out. Or Whether load combinations (COs) or result combinations (RCs) are created. See Figure 03.If COs or TOs are already available in the existing file, a query appears asking if the program should delete or keep the existing combinations. See Figure 04.
AnswerThe individual members of a set of members must have an identical orientation. Furthermore, the orientation of the members and the set of members must match.Solution:In the Display navigator, you can display and check the orientation of members and sets of members. Use the shortcut menu to invert the Orientation of a member or set of members (see Figure 03)
AnswerThe option to control how new structural elements are applied to the already existing, deformed structure in the design states.Starting position:The new elements are applied with orientation to the initial position, that is, the provided geometry. The deformations are compensated throughout the construction process. Theoretically, there is a buckling in the geometry (Figure 02 1.)Tangential:The new elements are applied with the orientation of already deformed elements that are already existing, that is, tangent to them. Deformations are not compensated during the construction process. Theoretically, there is no buckling in the geometry (Figure 02 2.)
