Use the successful frame and truss analysis software to RSTAB to calculate 2D or 3D frame & truss structures made of steel, concrete, timber, aluminum, or other materials.
RSTAB allows you to quickly and easily define the structural model and then calculate internal forces, deformations and support reactions. For design checks, there are add-ons available that allow you to take into account specific conditions related to materials and standards.
Are you still looking for an eligible structural analysis program? As a structural engineer, you have certain requirements, of course. RSTAB 9 is available for you as 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.
Opt for the established Dlubal program RSTAB 9 to facilitate your work with structures. Due to its sophisticated input technology, it allows you to intuitively model simple and complex structures. RSTAB 9 is the basis of a modular software concept. Its powerful computation solver allows for linear and nonlinear calculations of internal forces, deformations, and support reactions.
The add-ons integrated directly in the program allow you to carry out additional analyses and design checks according to various standards (for example, in reinforced concrete, steel, and timber structures). Compile a program package that is precisely tailored to your individual needs and projects. It is possible to upgrade the program at any time.
The graphical workspace is the central part of the user interface. This is where you create the model, define loads and evaluate results. You can intuitively control the view by clicking or rotating the cube (hold down the left mouse button and move the mouse pointer). Alternatively, you can also adjust the view directly using the mouse functions.
Navigator
The Navigator manages the model data clearly in a tree structure. At the bottom, there are three tabs (four after the calculation) that allow you to easily switch between the Data, Display, Views, and Results sections.
Tables
The data is managed in a clear and organized manner in the form of a spreadsheet in the Tables. You can select a specific table using the lists of main categories and their associated subcategories.
Control Panel
The Control Panel contains a legend that makes it easier to find your way around the model results. In addition, the control panel provides basic controls that you can use to customize and optimize the display of the results.
The Dlubal programs are characterized by their user-friendly and easy-to-learn user interface - this applies in particular to RSTAB 9. You can conveniently create and edit your structure in a CAD-like environment or by using clearly arranged tables.
Right-clicking opens shortcut menus directly on graphic or navigator objects, allowing you to quickly create or edit them. The intuitive surface allows for quick definition of structural and load objects as well as easy customization.
Further highlights of the program interface include:
RSTAB is a very powerful calculation software, as it allows the designer to model any type of structure in a very academic and scrupulous way, with the simplicity and practicality that is needed in the profession. It's easy to obtain an analysis model very close to reality without many input difficulties.
I have been working with Dlubal programs for many years, with interruptions of up to one year. I was able to monitor the progress of your software. It is always nice to see how fast you get back after a long break. Currently, I am carrying out detailed analyses utilizing RFEM. I have imported an entire model from RSTAB into RFEM and build on it.
Select any of the useful auxiliary functions and tools that make the modeling easier for you. This facilitates the generation of snow and wind loads, for example. Furthermore, you can consider member and hinge nonlinearities (yielding, tearing, slippage, and so on), as well as couplings or member eccentricities.
These features also support you when modeling your structures:
Your model is calculated precisely and quickly. The model is calculated linearly according to the linear static analysis, or nonlinearly according to the second-order or the large deformation analysis. In order to determine design internal forces, you can be superimpose the results in combinations.
If you are looking for models to practice on or as inspiration for your projects, you've come to the right place. We provide you with a vast number of structural analysis models to download, such as RFEM, RSTAB, RSECTION, or RWIND files.
RWIND is a program (digital wind tunnel) for the numerical simulation of wind flows around any building geometry with determination of the wind loads on their surfaces. RWIND is available in a Basic and Pro version.
To model the bodies in RWIND Basic, you will find a special application in RSTAB. In this application, you define the wind directions to be analyzed using related angular positions around the vertical model axis.
Your results and data in RSTAB 9 are displayed transparently and archived efficiently. Tabular and graphical results of internal forces, deformations, and support forces are available directly in the model. You can select your results using various filter criteria. All data is documented in a multilingual printout report, the content of which you can easily adapt and save as a template. Furthermore, RSTAB 9 allows you to easily integrate graphics, texts, MathML formulas, and PDF documents into your report.
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 and clear order processing. Furthermore, your customer data including the licensed programs and add-ons is organized in the Dlubal Center.
If stormy or windy conditions prevail in your planning, RSTAB offers you a firm hold. As a standard feature, RSTAB includes helpful tools for generating wind loads, snow loads, and so on, as well as for converting surface loads into member loads.
The Dlubal programs focus on efficient and uncomplicated work. Therefore, RSTAB can automatically generate action and load combinations, as well as design situations according to Eurocode and other international standards. It follows the corresponding combination expressions. For example, you can also copy or add load cases in a clearly arranged window. Furthermore, the load cases and combinations can also be easily managed in tables.
