  1. Simulation of Thermal Strains with Specification of Absolute Temperatures

    Simulation of Thermal Strains with Specification of Absolute Temperatures

    The structural analysis programs RFEM and RSTAB are able to simulate a thermal strain of structural components by means of temperature loads. The temperature loads are subdivided, because global changes in the temperature of structural components involve a membrane effect, and because temperature changes in relation to the height of structural components implicate bending effects. Temperature load application is now divided into the following two types.

  2. Fire Protection Design According to DIN EN 1993-1-2 (Eurocode 3)

    Fire Protection Design According to DIN EN 1993-1-2 (Eurocode 3)

    The RF-/STEEL EC3 add‑on module for RFEM and RSTAB allows for the fire protection design of structural steel components. The simplified analysis is performed by determining the steel temperature iteratively for a particular point of time. Currently, you can apply three different fire situations for the temperature determination.

  3. Creating Lateral Intermediate Supports

    Creating Lateral Intermediate Supports

    In RF-/STEEL EC3, the Window 1.4 Lateral Intermediate Supports offers you the option to define lateral intermediate supports at individual members. These supports are created from connected purlins and horizontal beams, for example, and increase the resistance against lateral-torsional buckling. Lateral intermediate supports can be entered either with a relative or an absolute distance.
