AnswerThe design points in CRANEWAY have been adopted in compliance with the standard. In this case, the stresses are calculated for the following locations:
These points are not displayed in the resulting cross-section graphic in the CRANEWAY program. However, there is always a stress point at the design points 0 and 2 for which the result values can be directly displayed.
- Design Point 0
A periphery of the flange at the web edge or at the fillet start
- Design Point 1
A flange at load application point (this can be checked as wheel spacing in Window 1.4)
- Design Point 2
The flange edge
- Design Point 0
AnswerDuring the development of the FRAME‑JOINT Pro add on module, the bottom end plate extension was introduced as it causes an improved load transfer of the compression force into the column.
It is not possible to deactivate the extension and the minimum dimension of it is defined as follows:
uu = max
- End plate thickness
- √2 * bottom flange weld
- for end plate height < 200 mm → min 10 mm
- for end plate height > 200 < 400 mm → min 20 mm
- for end plate height > 400 → min 30 mm
AnswerTo add different supports to a structural component, this must consist of several members and the design must be carried out by using a set of members. It is then possible to assign different parameters to the individual members. The video shows the procedure.
AnswerEspecially in the case of the "Column web, Compression Force, Bottom" design, a specified web stiffener is only applied to the design if it is actually required, or if the design cannot be performed without the web stiffener. In the latter case, the comment "Web stiffener required" appears in the last column of the result table.It is also important to note whether a continuous or a partial rib is applied.In the case of the partial rib, the compressive force is divided into a web and a rib and designed in this way.If a continuous rib is used, the column web is first fully loaded and the excess load is applied to the rib. In the case of T-joints and cross joints, this approach prevents the rib from being overloaded.
The geometry depends on the definition of the structural components. In Window "1.2 Nodes and Members," there is the specification of which member is calculated as a column and which one as a beam. The program always recognizes the column as a continuous structural component by default (see Figure 01).In order to make the beam continuous, simply change the status of the individual members (see Figure 02). The actual beam will have the "Column" status and the actual column will be defined as a "Beam."
When designing one or more members with a circular cross-section, As,top and As,bottom are no longer displayed: For such cross-sections, "top" and "bottom" cannot be defined; the "circular" reinforcement is created, see Figure 01.
Solution: Create a separate design case for the circular cross-sections (select "File → New Case" in the module menu) and design the corresponding members separately. In the other design case, delete the members with circular cross-sections. After the calculation, As,top and As,bottom will be displayed in the Results navigator, see Figure 02.
AnswerIn RF-CONCRETE Surfaces, the "top" or "bottom" position is controlled by the orientation of the area's local coordinate system.See also the FAQ000740This means for a wall that As, below or As, above can either be the reinforcement on the outside or inside depending on the orientation of the local z-axis.Both values must be taken into account for the reinforcement planning.So the sum of A s, below + A s, above .

Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
