Basics to Determine and Evaluate Influence Lines
Influence lines have become less important nowadays due to the fast computer systems. However, it might be an advantage to use influence lines in the phase of preliminary design, but also in the actual creation of the structural designs. With the RF-INFLUENCE add-on module, it is possible to generate and evaluate influence lines and influence surfaces easily due to a fixed internal force. This technical article describes with a simple example the basics to determine and evaluate influence lines. -
Determination of Effective Lengths in RF-/CONCRETE Columns
With RF-/CONCRETE Columns, it is possible to determine effective lengths for columns automatically. This article describes which entries are necessary and how the calculation of the effective lengths is carried out. -
Modeling Containers by Generating a 3D Cell
With the function "Generate Model - Members" → "3D Cell", it is very easy to generate containers (shipping containers, office containers, mobile homes, etc.) with regular and irregular distribution of the cells. -
Warping Torsion Analysis According to AISC Design Guide 9
The design of a torsional loaded beam according to AISC Design Guide 9 will be shown based on a verification example. The design will be performed with the RF-STEEL AISC add-on module and the RF-STEEL Warping Torsion module extension with 7 degrees of freedom. -
Consideration of Possible Contact Between Overlapping Members
From time to time it happens that two intersecting beams overlap at a short distance. -
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. -
Modeling and Bending Design of Point-Supported Flat Slab
This article describes how a flat slab is generated as 2D model in RFEM and the loading is applied according to Eurocode 1. -
Assistance Tools for Cable Structures
RFEM and RSTAB are able to cover a large number of branches in the field of building and construction industry with their generally usable structural frame analysis and FEM programs. The design of cable structures is thus also possible in both software solutions. In the following, some assistance tools for modeling and design will be presented. -
Influence of Slip of Standardized Joints in Steel Structures
This article deals with the stiffness of standardized joints according to the DSTV (German Steel Construction Association)/DASt (German Committee for Structural Steelwork) standards, often used in steel construction, and its effects on structural analysis and design results according to DIN EN 1993-1-1. -
Fin Plate Connections: Theory and Application
Fin plate connections are a popular form of pinned steel connections and are commonly used for secondary beams in steel structures. They can be easily used in beam structures arranged on the top edge, e.g. working platforms. Manufacturing expenditures in the workshop as well as the assembly costs on-site are normally manageable. The design seems to be completed easily and quickly, but has to be put into perspective to a certain extent in the following. Moreover, this connection type is basically possible as pinned beam to beam or pinned beam to column connection, whereas the first case is the more common one in design practice.
