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.

Iterative RFEM Calculation with Load Increments
The calculation in RFEM is usually carried out in several calculation steps, the so-called iterations. It is then possible to consider particular characteristics of the model such as objects with nonlinear functions. In addition, by using the iterative calculation, nonlinear effects are taken into account which result from changes in deformation and internal forces in case of the second-order analysis or when considering large deformations (cable theory). In case of complex models, geometric linear calculations are usually not sufficient.

Entering Lateral Supports and Their Effects in RF-/STEEL EC3
When designing steel columns or steel beams, it is usually necessary to carry out cross-section and stability analyses. In most cases, cross-section design can be carried out without giving further details; the stability design, however, needs additional user-defined specifications. To a certain extent, the member is cut out from the structure and therefore, the support conditions have to be specified. This is particularly important to determine the ideal critical moment for lateral torsional buckling Mcr. In addition, the correct effective lengths Lcr have to be defined. They are necessary for the internal calculation of the slenderness ratios. -
Stability Analysis of Steel Column According to EN 1993-1-1
This article is about the stability analysis of a steel column with axial compression according to EN 1993-1-1 Clause 6.3.1. Additionally, a variation study is carried out aiming at steel optimization. -
Load Combinations in Timber Structures for European and American Timber Standards
In addition to determine loads, there are some particularities concerning the load combinatorics in timber design which have to be considered. Contrary to steel structures where the largest loading results from all unfavorable actions, in timber construction, the strength values are dependent on the load duration and the timber humidity. Special characteristics have to be considered as well for the serviceability limit state design. The following article discusses the effects on the design of wooden elements and how this is possible with RSTAB and RFEM.

Wind Load on Monopitch and Duopitch Roofs in Germany
In Germany, DIN EN 1991-1-4 with the National Annex DIN EN 1991-1-4/NA regulates the wind loads. The standard applies to civil engineering works up to an altitude of 300 m. -
Distribution Coefficient ζ in the Deformation Analysis of Reinforced Concrete Components
Performing serviceability limit state design also includes taking into account the allowable deformation. The calculation of the deformation of reinforced concrete components depends on whether or not the observed cross-section is cracking under the applied loading. The governing control parameter in RF-CONCRETE Deflect is the distribution coefficient ζ. -
Cross-Section Design of Two-Span Beam
The cross-section class of a two-span beam will be designed in the following. In addition, the necessary cross-section designs will be performed. The global stability failure will be excluded due to sufficient stabilizing measures. -
Modeling a Girder Grillage
The structural analysis of a girder grillage is usually no big deal when using computer-aided calculation. There are different options to display and analyze a structure. They include, for example, the conventional way with performing structural analysis of components or modeling the entire structure. -
