The structural analysis software RFEM 6 is the basis of a modular software system. The main program RFEM 6 is used to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. The program also allows you to create combined structures as well as to model solid and contact elements.
RSTAB 9 is a powerful analysis and design software for 3D beam, frame, or truss structure calculations, reflecting the current state of the art and helping structural engineers meet requirements in modern civil engineering.
Do you often spend too long calculating cross-sections? Dlubal Software and the RSECTION stand-alone program facilitate your work by determining section properties of various cross-sections and performing a subsequent stress analysis.
Do you always know where the wind is blowing from? From the direction of innovation, of course! With RWIND 3, you have a program at your side that uses a digital wind tunnel for the numerical simulation of wind flows. The program simulates these flows around any building geometry and determines the wind loads on the surfaces.
Are you looking for an overview of snow load zones, wind zones, and seismic zones? Then you are in the right place. Use the Geo-Zone Tool to determine quickly and efficiently snow loads, wind speeds, and seismic data according to ASCE 7‑16 and other international standards.
Would you like to try out the capabilities of the Dlubal Software programs? You have the opportunity to do so! The free 90-day full version allows you to thoroughly test all our programs.
This is very easy. The following example shows you this.
Preparation
The web requests to the Geo-Zone Tool using Python require:
To run a web request of the Geo-Zone Tool, you need the information for the Geo-Zone Tool. This is explained in the following article using the example of the query URL structure:→ Controlling WebService (API)
In this example, the following information is used, which you can replace with your own in the script:
Executing Web Request and Reading Data
The following script queries the web service of the Geo-Zone Tool and documents the required times and content.
This leads to the following results, for example:
Addition: Preparing Web Request Content
The following script converts the text obtained from the Geo-Zone Tool web service into a tabular form. Furthermore, the result values are separated from their units and finally saved as a CSV and an Excel file.
This results in the following, for example:
If you want to specify your own design results for a structural component of one design situation type for different configurations, the "Construction Stages Analysis (CSA)" add-on provides a solution. Among other things, this add-on allows you to perform a parallel simulation of a model with a constant number of objects. In this special case, the base model is internally juxtaposed several times, and can thus be transferred to the design with differently set design configurations.
For the conversion, you can proceed as follows:
Open the "Base Data" dialog box using the menu command "File > Base Data".
Then, open the Add-ons tab and select the add-ons you want to use.
Click "OK" to close the dialog box.
When designing cross-laminated timber (CLT) panels, the calculated moment capacities in the major strength direction (β = 0°) should be multiplied by 0.85 for conservatism according to the American National Standard Institute ANSI/APA PRG 320.
This value is known as the conservatism factor, Ccon in the Timber Design add-on and can be adjusted under the Strength Configuration for NDS.
The stability design checks according to EN 1993‑1‑1, 6.3, are not included in RSECTION 1.
According to EN 1993‑1‑1, 5.2.2 (7) a), the stability analysis may be performed as a cross-section design, provided that a spatial calculation according to the second-order analysis is performed while applying global and local imperfections. In order to model the lateral-torsional buckling, it is necessary to determine the internal forces according to the geometrically nonlinear torsional buckling analysis with regard to warping torsion. It is only necessary to perform the section design, as all stability effects are covered by the calculation.
In RSECTION 1, you can calculate the stresses due to the axial force, biaxial bending moments and shear forces, primary and secondary torsional moment, as well as warping bimoment for any cross-section shape. This way, you can use the design method described in EN 1993‑1‑1, 5.2.2 (7) a) in RSECTION 1.
Using the Effective Sections (Extension for RSECTION 1) add-on, you can perform the classification according to EN 1993‑1‑1 and the calculation of the effective cross-section according to EN 1993‑1‑5.
The stability design checks according to EN 1999‑1‑1, 6.3, are not included in RSECTION 1.
According to EN 1999‑1‑1, 5.2.2 (5) a), the stability analysis may be performed as a cross-section design, provided that a spatial calculation according to the second-order analysis is performed while applying global and local imperfections. In order to model the lateral-torsional buckling, it is necessary to determine the internal forces according to the geometrically nonlinear torsional buckling analysis with regard to warping torsion. It is only necessary to perform the section design, as all stability effects are covered by the calculation.
In RSECTION 1, you can calculate the stresses due to the axial force, biaxial bending moments and shear forces, primary and secondary torsional moment, as well as warping bimoment for any cross-section shape. This way, you can use the design method described in EN 1999‑1‑1, 5.2.2 (5) a) in RSECTION 1.
Using the Effective Sections (Extension for RSECTION 1) add-on, you can also perform a classification and calculate the effective cross-section according to EN 1999‑1‑1.
In the Steel Joints add-on, the order of components plays an important role when editing a joint: It "runs" from top to bottom.
For example, if you want to edit a plate, you have to define the "Plate" in the list of components first, before defining the "Plate Editor" component. The same principle applies to other components, such as "Plate Cut".
The attached video shows in detail how to proceed when modeling without using the component library.
Currently, it is not possible to calculate composite beams in RFEM. The corresponding add-on for the analysis of composite structures or composite structural components is in preparation.
Yes, the dimensioning function is available in every graphics window of the "New Steel Joint" or "Edit Steel Joint" dialog box. However, the geometry of a connection is your concern in most cases. Therefore, open the "Components" tab and right-click in the graphic window. Then, select the New Dimension function in the shortcut menu. The "Linear" and "Angular" options are suitable for the dimensioning of joints.
A dialog box known from RFEM appears, where you can control the settings of the dimensions. The graphic provides you with the possible snap points. When moving the pointer over the components, suitable snap points are displayed.
Click the desired snap points (multiple selection is possible) and place the chain dimensioning.
It is possible to show or hide the dimensions using the toolbar or delete them using the shortcut menu of the dimension line.
