Knowledge Base Articles

In this article, the calculation of a timber panel wall with the beam panel thickness type is compared with a manual calculation.

KB 001848 | Timber Column Design as per the 2018 NDS Standard in RFEM 6

Using the Timber Design add-on, 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 strength calculated by the Timber Design add-on using step-by-step analytical equations as per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.

KB 001825 | WebService & API for Analysis of Construction Stages

When calculating regular structures, data input is often not complicated but time-consuming. Input automation can save valuable time. The task described in the present article is to consider the stories of a house as single construction stages. Data is entered using a C# program so that the user does not have to enter the elements of the individual floors manually.

Our webservice offers users the opportunity to communicate with RFEM 6 and RSTAB 9 using various programming languages. Dlubal's high-level functions (HLFs) allow you to expand and simplify the WebService's functionality. In line with RFEM 6 and RSTAB 9, using our WebService makes the engineer's work easier and faster. Check it out now! This tutorial shows you how to use the C# library by means of a simple example.

Product Features

Feature 002824 | OSB Material for USA and Canada

In RFEM, the oriented strand board (OSB) material is available for the USA and Canada. The material parameters are taken from the "Panel Design Specification manual".

Using the "Beam Panel" thickness type, you can model timber panel elements in 3D space. Simply specify the surface geometry and the timber panel elements are automatically generated using an internal member-surface construct, including the element connection stiffness. The Beam Panel thickness type is defined using the Multilayer Surfaces add-on.

A "beam panel" provides you with the following advantages:

Single-sided or double-sided sheathing
Automatic calculation of a semi-rigid coupling between studs and sheathing
- Nailed sheathing connection
- Stapled sheathing connection
- User-defined sheathing connection
Representation as a complete geometric 3D object (frame, studs, surface, etc.), including eccentricity and automatically calculated stiffness between elements
Consider openings via surface cells
Design of the individual structural elements utilizing the Timber Design add-on (full shear wall design planned for a future release)
Other material options available (e.g., particle board, gypsum, or fiberboard sheathing with cold-formed steel sections)

Feature 002585 | Fire Resistance Design of Surfaces for EN 1995 and SIA 265

You have the option to perform the fire resistance design of surfaces using the reduced cross-section method. The reduction is applied over the surface thickness. It is possible to perform the design checks for all timber materials allowed for the design.

For cross-laminated timber, depending on the type of adhesive, you can select whether it is possible for individual carbonized layer parts to fall off, and whether you can expect increased charring in certain layer areas.

Feature 002615 | Cross-Laminated Timber Manufacturer Library for USA, Canada, and Switzerland

Among others, the following cross-laminated timber manufacturers are available in the layer structure library:

Binderholz (USA)
KLH (USA, CAN)
Kalesnikoff (USA, CAN)
Nordic Structures (USA, CAN)
Mercer Mass Timber
SmartLam
Sterling Structural
Superstructures listed in Lignatec Edition 32 "Cross-Laminated Timber of Swiss Production"

By importing a structure from the layer structure library, all relevant parameters are adopted automatically. The library is continually updated.

Frequently Asked Questions (FAQ)

What are the stiffness reduction factors k₃₃ and k₈₈ in the Multilayer Surfaces Add-on?

How can the NDS and CSA O86 factors be manually adjusted for consideration in the Timber Design add-on?

What calculation is carried out for the NDS Strength Configuration "Calculation of Torsion" options?

Which Dlubal software products do you recommend for the structural analysis and design of timber structures in particular?

How can I model a timber beam with stiffening on both sides? (splice)

How can I generate an area load on members via cells in RFEM 6 or RSTAB 9?
