Frame Analysis Software RSTAB 9 | Load Generation

Structural Engineering Analysis & Design Software

To avoid the snow, wind, and others become a load for your project, we recommend you using the successful frame & truss analysis software RSTAB. This program allows you to design beam, frame, or truss structures consisting of steel, reinforced concrete, timber, aluminum, or other materials.

With RSTAB, you can easily and quickly define a structural model and then calculate the internal forces, deformations, and support reactions. There are design add-ons at your side that you can use to consider the material- and standard-specific requirements.

Quick and Easy Generation of Loads

The Best Structural Modeling Program

"We are dealing with Structural and Seismic Engineering since 1998. Dlubal Software is, in our experience, the best structural modeling program on the market. We recommend it to all those who need to deal with special and daily cases."

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.


Generation of Snow Loads

Do your structures also have to withstand snowfalls? Use the Snow Load Wizard to generate snow loads as member loads or surface loads.

The following standards are available:

  • European Union EN 1991-1-3 (incl. National Annexes)
  • United States ASCE 7
  • Canada NBC
  • Switzerland SIA 261
  • Spain CTE DB-SE-AE
  • People's Republic of China GB 50009
  • India IS 875

Generation of Wind Loads

Wind loads are also not a problem in your design. You can automatically generate wind loads as member loads or area loads (RFEM) on the following structural components:

  • Vertical walls
  • Flat roofs
  • Monopitch roofs
  • Duopitch/troughed roofs
  • Vertical walls with duopitch roof
  • Vertical walls with flat/monopitch roof

The following standards are available to you:

  • European Union EN 1991-1-3 (incl. National Annexes)
  • Spain CTE DB-SE-AE
  • People's Republic of China GB 50009

Generating Member/Line Loads from Area Loads

Use all types of loads without any difficulty. You can automatically convert the area loads into member loads or line loads (RFEM).
In the case of member loads from area loads, you have to define a plane via corner nodes or select cells in the graphic. Then the rest works by itself.


Generating Member Loads from Free Line Loads

Also for pure member models, such as girder grillages, there is a useful feature for you. Here you can define free line loads (for example, from conveyor belts) and transfer them proportionally to members.

Special Solutions

First, the two-part Optimization & Costs / CO2 Emission Estimation add-on finds suitable parameters for parameterized models and blocks via the artificial intelligence (AI) technique of particle swarm optimization (PSO) for compliance with common optimization criteria. Second, this add-on estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for the structural model.

Pushover Analysis

Dynamic Analysis

Earthquakes may have a significant impact on the deformation behavior of buildings. A pushover analysis allows you to analyze the deformation behavior of buildings and compare them with seismic actions. Using the Pushover add-on, you can analyze the seismic actions on a particular building and thus assess whether the building can withstand the earthquake.
