Wind Simulation & Wind Load Generation

With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.

The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

  1. Shear Deformations of Framework Structures in Timber Construction

    In current literature, the formulas to determine internal forces and deformations manually are usually specified without considering the shear deformation. Especially in timber construction, the deformations resulting from shear force are often underestimated.

  2. Impact of a Passenger Car on a Carport

    Impact Load of a Passenger Car on a Carport

    The fundamental requirements of a structural system are, according to the basis of structural design, sufficient ultimate limit state, serviceability and resistance. Structures must be designed in such a way that no damage occurs due to events such as the impact of a vehicle.

  3. 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.

  4. Figure 01 - Structural System and Cross-Section Dimension According to [1]

    Modeling of Semi-Rigid Composite Beam Made of Timber as Surface Model

    There are several options to calculate a semi-rigid composite beam. They differ primarily in the type of modeling. Whereas the Gamma method ensures a simple modeling, additional efforts are required when using other methods (e.g. shear analogy) for the modeling which are, however, offset by the much more flexible application compared to the Gamma method.
  5. Design of Curved Glulam Beams According to ANSI/AWC NDS

    RFEM offers the possibility to model also curved beams. For this, a curved line must first be created (see Figure 01). Then, a member with a cross-section can be assigned to this line. The advantages over modelling with beam segments are the easier handling during the modelling as well as the clearer results output of the internal forces.

  6. Generating Wind Loads on Walls and Roofs According to ASCE/SEI 7-16

    RFEM and RSTAB allow you to easily consider wind load effects on a three-dimensional building according to ASCE/SEI 7‑16 [1]. This article explains the complex theory of entering wind loads in the software. You can find the wind load under 'Tools' → 'Generate Loads' → 'From Wind Loads'.

  7. Stability Analysis of Two-Dimensional Structural Components on Example of Cross-Laminated Timber Wall 3

    As an alternative to replacement bar method in this paper, the possibility will be explained to determine the internal forces of the risk of bending wall 2nd order theory taking into account imperfections and then perform a measurement of the cross section for bending and pressure.

  8. Stability Analysis of Two-Dimensional Structural Components on Example of Cross-Laminated Timber Wall 2

    The following article describes design using the equivalent member method according to [1] Section 6.3.2, performed on the example of cross-laminated timber wall susceptible to buckling described in Part 1 of this article series. The buckling analysis will be performed as a compressive stress analysis with reduced compressive strength. For this, the instability factor kc is determined, which depends primarily on the component slenderness and the support type.

  9. Stability Analysis of Two-Dimensional Structural Components on Example of Cross-Laminated Timber Wall 1

    Basically, you can design structural components made of cross-laminated timber in the RF-LAMINATE add-on module. Since the design is a pure elastic stress analysis, it is necessary to additionally consider the stability issues (flexural buckling and lateral-torsional buckling).

  10. New Display Function for Dimensions: Fixed Length Extension Lines

    In RFEM and RSTAB, it is now possible to define the guidelines of dimensions with a fixed length. This new option allows you to define dimensions without having the structure covered by the guidelines. In this way, dimensioning is clearer. You can activate this option under “Display Properties” → “General” → “Dimensions”.
