Visualization of the shear flow result diagram and acting forces on a timber panel wall
In this article, the design of a timber panel wall with the beam panel thickness type is performed.
Illustration of equivalent lateral force method for seismic analysis in structural engineering
This article provides a comprehensive overview of essential seismic analysis methods, explaining their principles and applications, as well as the scenarios in which they are most effective
Fire design according to Chapter 16 of the NDS [1] for wood members and surfaces is available in the Timber Design add-on. This article shows how the charring of wood and reduced cross-sectional dimensions can be accounted for in the fire design with an example from AWC Technical Report No. 10 [2].
KB 001825 | WebService & API for Analysis of Construction Stages
When calculating regular structures, data input is often not complicated, but it is time-consuming. Save your valuable time with input automation. The task described in the present article is to consider the stories of a house as single construction stages. Data are entered using a C# program so that the user does not have to enter the elements of the individual floors manually.

Product Features
Feature 002901 | Plywood Materials According to ANSI/APA PRG 510 Plywood Standard (USA/CAN) in RFEM Material Library

In the material library of RFEM, you can find plywood materials according to the US and Canadian standards ANSI/APA PRG 510 Plywood (USA/CAN).

Feature 002792 | Visualization of a timber panel element, modeled with the Beam Panel thickness type for structured 3D models.

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 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.

Feature 002668 | Curved Section Distributions

Would you like to calculate curved beams (for example, made of glued-laminated timber)? For this purpose, you can use various section distributions for members:

  • Curved
  • Pitched cambered beam with constant height
  • Pitched cambered beam with variable height
  • Fish beam | Parabolic
  • Fish beam | Linear with rounding in central area
