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.
The Masonry Design add-on allows you to automatically determine the stiffness of your wall-slab hinge. The diagrams were determined as part of the research project DDmaS - "Digitizing the design of masonry structures" and are derived from the standard.
Define a line hinge on the connection line of both surfaces and activate the slab-wall connection.
You can now enter your parameters in the Slab-Wall Connection tab. Then, click the Regenerate [...] button.
The determined diagrams are displayed subsequently.
The Building Model and the feature of modeling stories with "Rigid Diaphragm" is not designed for all building types.
The function was primarily developed for 3D buildings with 5-10 stories (or more) with a regular or the same floor plan. This means that you should only assign the "Rigid Diaphragm" function to the slabs where the walls and columns are positioned identically in the stories above and below. If this is not the case, instability may occur.
If the model has been entered correctly according to this convention, three options for the result display will be available to you:
The "Total" result display shows the results on the entire vertical components (that is, walls, shear walls, columns, and so on). See Image 02. If you select "Floors only", the results for the separate calculation of slabs are displayed as a 2D model. The "Combination" option corresponds to the same results from both result types mentioned above.
For smaller 3D models and buildings with different floor plans, it is still better to work with the usual modeling as a 3D model. If you are working with models that sometimes have regular floor plans, you can alternatively assign the "Rigid Diaphragm" option to the individual floor slabs. The floor plan geometry of the stories above and below this slab should then be the same again.
The fundamental extraction of a 2D floor from any 3D model is not possible with the technology implemented for this add-on function.
Yes, you can control the load distribution by setting the limit stresses for tension as very high or small.
