For the combination of actions, you have come to the right place. If you use them in the ultimate and the serviceability limit state, you can select various design situations according to the standard (for example, ULS (STR/GEO) - permanent/transient, SLS - quasi-permanent, and others). Optionally, you can also integrate imperfections in the combination and determine load cases that should not be combined with other load cases (for example, construction load for roof not combined with snow load).
The material library of RFEM and RSTAB includes the timber materials according to the American standard ANSI/AWC NDS‑2024.
In addition to JavaScript, the Python high-level functions are also available in the console. Using the Python option, the console also provides you with the Python HLF functions known from the WebService function catalog for further use in the object properties dialog box for in-app scripting.
The "Bracing in Cells" function allows you to generate diagonal bracing with just a few clicks. You can find this feature under Tools → Generate Model – Members → Bracing in Cells.
In RFEM and RSTAB, you can visualize the flow field quantities of pressure, velocity, turbulence kinetic energy, and turbulence dissipation rate for the wind simulation.
The clipping planes are aligned with the respective wind direction.
