Why Dlubal Software?
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.

Lateral-Torsional Buckling in Timber Construction | Examples 1
The article Lateral-Torsional Buckling in Timber Construction | Theory explains the theoretical background for the analytical determination of the critical bending moment Mcrit or the critical bending stress σcrit for the lateral buckling of a bending beam. The following article uses examples to verify the analytical solution with the result from the eigenvalue analysis.

Timber Column Design per the 2018 NDS Standard
Using the RF-TIMBER AWC module, timber column design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member compressive capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling in RF-TIMBER AWC using step-by-step analytical equations per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.

Lateral-Torsional Buckling in Timber Construction: Theory
Slender bending beams with a large h/w ratio and loaded parallel to the minor axis tend to have stability issues. This is due to the deflection of the compression chord.

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.

Calculating Timber Panel Walls | 1. Determining the Ultimate Limit State and Stiffness
The stiffening of timber structures is usually carried out by means of timber panels. For this purpose, structural components consisting of slabs (chipboards, OSB) are connected with members. Several articles will describe the basics of this construction method and the calculation in the RFEM program. This first article describes the basic determination of the stiffnesses as well as the calculation.

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.

2018 NDS Updates for Cross-Laminated Timber Design
The American Wood Council (AWC) has released the 2018 Edition of the National Design Specification (NDS) for Wood Construction. This is the second edition of the NDS to contain a chapter dedicated to cross-laminated timber (CLT) design. Therefore, a couple of revisions were included in the 2018 NDS when compared to the previous 2015 Edition.
