Useful Program Features
The Knowledge Base includes technical articles on a wide array of structural analysis and design topics.
These articles are intended to help you navigate through the Dlubal programs, learn efficient tips and tricks, and provide further insight to the program features.
Why Dlubal Software?
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.
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.
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.
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.
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.
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.
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.
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.
