  1. Window 1.5 Effective Lengths - Members

    Fire Resistance Design According to DIN EN 1993-1-2

    The fire resistance design can be performed according to EN 1993-1-2 in RF-/STEEL EC3. The design is carried out according to the simplified calculation method for the ultimate limit state. Claddings with different physical properties can be selected as fire protection measures. You can select the standard temperature-time curve, the external fire curve, and the hydrocarbon curve to determine the gas temperature.

  2. Figure 01 - Creating a Parts List

    COM Interface in VBA | Creating a Parts List

    Parts lists give information about which and how many parts are necessary for creating a building. They are the basis for identifying the needs and purchasing the components. Parts lists can be created in the design modules such as RF-/STEEL EC3, RF-/TIMBER Pro and so on. Additionally, a customized parts list can be created with the RF-COM/RS-COM interface.

  3. Figure 01 - Cross-Section

    Stiffened Buckling Panels According to EN 1993-1-5, Section 4.5

    In SHAPE-THIN, it is possible to perform the calculation of stiffened buckling panels according to Section 4.5 of EN 1993-1-5. For stiffened buckling panels, the effective surfaces due to local buckling of the single panels in the plate and in the stiffeners as well as the effective surfaces from the entire panel buckling of the stiffened entire panel have to be considered.

    COM Interface in VBA | 5. Creating a Tool to Copy and Move Guidelines

    RF-COM/RS-COM is a programmable interface which allows the user to expand the main programmes RFEM and RSTAB by customized input macros or post‑processing programmes. In this article, a tool to copy and move selected guidelines in RFEM will be developed. It is possible to copy or move the guidelines also to another work plane. VBA in Excel will be used as programming environment.

    Creating Parametric Cross-Section

    The stand-alone program SHAPE‑THIN determines characteristic values and stresses of any thin‑walled cross‑sections. Graphic tools and features allow for modeling complex cross‑section shapes. In addition to the graphical input, it is also possible to enter the data in tables. As an alternative, you can import a DXF file and use it as a basis for further modeling. Also, each cross‑section can be entered using the cross‑section library of Dlubal Software and combined as a part with the user-defined elements.

  6. Throat Thickness a of Fillet Weld (a) and Deep Penetration Fillet Weld (b)

    Design of Fillet Welds According to EN 1993-1-8

    A fillet weld is the most common weld type in steel building construction. According to EN 1993‑1‑8, 4.3.2.1 (1) [1], fillet welds may be used for connecting structural parts where the fusion faces form an angle between 60° and 120°.

  7. Figure 01 - Layout and Dimensions of Cement Silo

    Loads on Silo Hopper According to EN 1991-4

    My previous article describes actions on silos according to EN 1991‑4. With an example of a free standing cylindrical silo for cement with a conical hopper, filling loads of the silo hopper were calculated.

  8. 1 - System

    Stiffening of Structures

    Buildings must be designed and dimensioned in such a way that both vertical and horizontal loads are conducted safely and without large deformations in the building. Examples of horizontal loads are wind, unintentional inclination, earthquakes, or a blast.

  9. Transferring National Annexes to Other Computers

    Transferring National Annexes to Other Computers

    RFEM and RSTAB provide the option to create national annexes with user‑defined partial safety factors and combination coefficients. It is also possible to transfer them to other computers.

  10. Text Formatting as Superscript or Subscript

    Text Formatting as Superscript or Subscript

    The printout report of RFEM/RSTAB includes a text block function. This feature allows you to create user‑defined text blocks with formatting and heading and add it to the printout report.
