Why Dlubal Software?
Building Information Modeling hits the headlines in building design. While some engineers only use BIM methods for planning, others deal with this topic for the first time or hardly have time for it in their daily working routine. However, one topic seems to be the most important in structural engineering: How can structural engineers benefit from BIM?
In RFEM and RSTAB, you can import DXF files via the import function. These DXF files can be used as the basis for modeling a structural system.
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.
The bachelor thesis of Daniel Dlubal focuses on presenting and highlighting the chances, advantages and opportunities of BIM when performing structural analysis and design of buildings. The essential information of a structural analysis is shown and the data exchange between CAD and structural engineering software is explained in detail as well.
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.
Part 4.1 of this article series described the connection of the RF‑/STEEL EC3 add‑on module and the members and load combinations to be designed were already defined. This part will focus on the optimization of cross‑sections in the module and the transfer to RFEM. The elements already explained in the previous parts are not described again.
In the BIM workflow, IFC files are frequently used as the basis for data exchange between CAD and structural engineering software. However, there is a fundamental problem with this approach. This article explains various types of IFC files, and provides an overview of the import and export options in the Dlubal Software programs.
Part 4.1 and 4.2 of this article series describes the optimization of a frame using the RF‑/STEEL EC3 add-on module. The fifth part explains how to link the module and get the relevant members. The elements already explained in the previous parts are not described again.
BIM is often used when it comes to data management in civil engineering. The individual disciplines of architecture, structural design, construction, and structural monitoring are coming closer together. Building Information Modeling makes this possible.
Dlubal Software provides a wide range of formats for data exchange. The following article explains the details of the interface with Autodesk Revit and, particularly the export settings.
