Structural Analysis Models to Download
The Dlubal programs always focus on simple and efficient operation. That's why there are numerous new features implemented in RSTAB 9, which facilitate your daily work with the structural analysis program. On this page, we present a selection of the new features.
Integration of All Add-ons
Discover the advantages of working with the various add-ons for RFEM 6 and RSTAB 9. All add-ons are integrated in the programs. This allows seamless interaction between the individual program parts and ensure that your analysis and design runs smoothly. Examples for this is the determination of the ideal overturning moment of timber beams using the "Torsional Warping (7 DOF)" add-on or the consideration of staggered form-finding processes by means of the "Construction Stages Analysis (CSA)" add-on, and so on.
Output of Design Check Formulas
With Dlubal Software, you always have an overview, regardless of whether your projects are from the reinforced concrete, steel, timber, aluminum, or other industry. The program clearly displays the design check formulas used in your design (including a reference to the used equation from the standard). These design check formulas can also be included in the printout report.
Member and Member Set Representatives
Make your work with members easier. For members and member sets with the same properties, you can define representatives for model organization, design, and documentation.
The results of these representatives can be easily displayed in the result tables.
Unit Stresses of Sections
Make sure nothing collapses on you: To estimate the resistance of member cross-sections, it is possible to display the unit stresses for the unit loads N = 1 kiP, My = 1 kiP/ft, and so on, when selecting the cross-sections.
The organization of imperfections is efficiently solved by imperfection cases. The cases allow you to describe an imperfection from local imperfections, equivalent loads, initial sway via table (new), a static deformation, a buckling mode, a dynamic mode shape, or a combination of all these types (new).
Use design situations to support your design checks. They allow you to collect the relevant load situations for design For example, you can define a design situation for the design of different materials.
Extension of Snow and Wind Load Wizards
Discover the new functions of the snow and wind load wizards:
- Loading of hybrid models made of members and surfaces (RFEM only)
- Connection to the Geo-Zone Tool (depending on the global construction site definition)
- Switching off surface sides
Modern Online Licensing System
Dlubal Software supports its customers with their construction planning worldwide. The modern online licensing system allows licenses of RFEM, RSTAB, and other programs to be distributed all over the world and assigned to the respective users via the Dlubal Account.
Improved Printout Report
Discover the fundamentally revised and optimized printout report. It offers you the following innovations, among other things:
- Quick creation due to non-modal printout report environment (parallel work in program and report possible)
- Interactive modification of chapters as well as creation of new user-defined chapters
- Import of PDFs, formulas, 3D graphics, and so on
- Output of the design check formulas used in the design (including a reference to the used equation from the standard)
- Modern printout report design
Do you have to calculate multiple load combinations in your models? Then several solvers (one per core) are initiated in parallel, each of which calculates a load combination. This ensures a better utilization of the cores and thus faster calculations.
Improved Result Diagram Window
Discover the new features in the result diagram window:
- Parallel work in the result diagram window and in the model
- Optional overlapping display of results (for example, several similar structural components in one image)
Webservice and API
Technology takes you further, also in your daily work with RFEM / RSTAB. The new API technology Webservice allows you to create your own desktop or web-based applications by controlling all objects included in RFEM 6 / RSTAB 9. Entire libraries and numerous functions are available to you. Thus, you can easily perform your own design checks, effective modeling of parametric structures, and optimization and automation processes using the programming languages Python and C#. Dlubal Software makes your work easier and more convenient. Convince yourself!
Extension of IFC Interface for Improved Open BIM Process
There are also improvements in the data exchange to make your work process easier. In addition to the import of IFC 2x3 (Coordination View & Structural Analysis View), the import and export of IFC 4 (Reference View & Structural Analysis View) is now supported.
Wind Simulation (RFEM or RSTAB Environment)
Discover the new features in RFEM and RSTAB for the determination of wind loads using RWIND:
- Useful load wizards for generating wind load cases with different flow fields in different wind directions
- Wind load cases with freely assignable analysis settings including a user-defined specification of the wind tunnel size and wind profile
- Comprehensive display of the wind tunnel with input wind profile and turbulence intensity profile
- Visualization and use of the RWIND simulation results
- Global definition of a terrain (horizontal planes, inclined plane, table)
Import of Construction Site for Load Determination
Always keep an eye on the natural conditions of your construction site by defining it on a digital map. The address data (including the altitude) as well as the snow load zone, wind zone, and seismic zone are imported automatically. The load wizard also uses this data.
The map is also displayed with the construction site marked in the "Model Parameters" tab.
Definition of Hotkeys
Would you like to make your work process more efficient? Then use hotkeys for various commands. This way, you can execute the frequently used commands quickly and easily with a previously assigned key combination.
By the way, this also works for your computer mouse. If it has other buttons in addition to the left, right, and middle buttons, you can assign a hotkey to them.
Assigning Loads to New Load CaseThis feature is useful for your daily work! For member loads, surface loads, and so on, you can retroactively move loads into another load case.
Mass LoadsThere is also an innovation in the load catalog that will interest you: The Mass Loads type has been added to the catalog!
Specification of Element TypesUse the specification of the element types for members, surfaces, solids, and so on, to facilitate your input (such as member nonlinearities, member stiffnesses, design supports, and many others).
The Dlubal Center ensures that your planning goes quickly and efficiently. Among other things, your projects and model files are managed here in a central location. Detailed information and graphics make it easier for you to assign all models and thus enable uncomplicated, clear processing of the project. Furthermore, your customer data including the licensed programs and add-ons is organized in the Dlubal Center.
Global Management of All Add-ons
Compile the right add-ons for your individual project. All add-ons are directly integrated in the program and, like all required design standards for the respective materials, are managed centrally.
Global Model Parameters
Define as many global model parameters as you want. You can also use them in the documentation.
Structured Data Navigator
You can now work even more efficiently with the Data Navigator. Its clear structure makes it easy to use. The navigator contains assignable types for objects as well as a hyperlink function that allows you to quickly jump to the assigned elements of an object.
Statistics for Sections
Keep an eye on your cross-sections. Useful statistical information, such as total length, total volume, total weight, and so on, is displayed for all cross-sections used in your project.
New Section Distribution Types for Members
There are seven new cross-section distribution types available for members (including arrangement function for aligning to a straight edge):
- Tapered at both sides
- Tapered at start of member
- Tapered at end of member
- Offset at both sides
- Offset at start of member
- Offset at end of member
Cross-Section Library with Short Text SearchSave your time in the cross-section library and use a short text search to quickly find a desired cross-section or cross-section series.
Structure Modification ObjectUse the new useful structure modification object to modify or deactivate stiffnesses, nonlinearities, and objects in a clear and load case-dependent way.
Using and Creating Model Blocks
Result Combinations Using Parenthesis TermsWhen creating result combinations, you can now also use parenthesized terms.
Individual Global Calculation Parameters for Load Cases and Load CombinationsUse the new structural analysis setting to provide load cases and load combinations with individual global calculation parameters.
New Combination WizardUse the new combination wizards to make your work easier. They fill the design situations with load or result combinations on the basis of an automatic or semi-automatic generation conforming to the standards.
Improved Load WizardTo make your work effiecient and quick, we have added new features to the load wizard. These include locking new members, smoothing occurring concentrated loads, and considering eccentricities as well as cross-section distribution.
Determination of Member Loads from Surface Loads by Specifying Cells and SurfacesAnother useful features in the Load Wiyard is the determination of member loads from area loads by defining surfaces (using corner nodes) and cells in a definition.
Global Organization of User-Defined Coordinate SystemsA change in favor of more efficient work withh the program: Your user-defined coordinate systems for input and analysis purposes are now organized globally under the guide objects.
Organization of Different Object SnapsTo facilitate your work, you can now define several object snaps for different operating tasks.
Object Selection as New Guide ObjectThis feature creates more order. The new guide object "Object Selection" allows for generic filtering of various objects.
- Basic objects
- Types for nodes
- Types for lines
- Types for surfaces
- Load Wizards
- Guide objects
Tabular Reference Description for Dimension LinesA clear arrangement of the Dlubal programs has a high priority. Therefore, the reference descriptions of incremental dimension lines are now given in tabular form for a better overview.
Implementation of SAF Format
Take your structural design one step further. RFEM 6 and RSTAB 9 support now a new file format for structural design, Structural Analysis Format (SAF). For this, both programs allow for the import as well as the export. SAF is a file format based on MS Excel, intended to facilitate the exchange of structural analysis models between different software applications.
ViewCubeTo facilitate the operation of the Dlubal programs, the new ViewCube in the graphic provides an intuitive selection of the correct model projection.
Tabular Unit SettingsWith a good visual organization, the work goes on more easily. You can now change certain units in the form of a tabular user interface.
New File Formats for ExportAn improvement that will benefit your smooth workflow: You can now export your RFEM and RSTAB models in XML, SAF, and VTK (results from RWIND).
New Local Axis Definition for MembersThe improvements in the international context are not neglected either. A new local axis specification (y upwards) has been added for the Anglo-American region.
New Graphic Printout Option with Preview ImageVarious new options make it easier for you to print graphics in the future. Your new graphic printout dialog now includes:
- Library-controlled mass print function for all program graphics
