Can I use RFEM to calculate a log house three-dimensionally?

Answer

For many users, the very realistic display of a building in construction programs arouses the wish to carry out the structural analysis of the building with the same complex spatial model.

Again and again, the design of log cabins is approached to us. Unfortunately, this attractive construction method is relatively complex for three-dimensional analysis. In dimensioning, there are some critical questions that cannot be answered.

  1. Which sorting class is the timber subject to? In a log house, unsorted damp wood is often used.
  2. How is the contact between the timber types controlled? Diamond notch, connection with moving timbers, and so on?
  3. Have mullions been installed? Which type of timber and how are they supported horizontally?
  4. Which dimensions does the timber have? In a log structure, a grown trunk can often be integrated. These trunks do not have uniform dimensions as the nature cannot be put into a grid.
  5. How is it possible to consider the contact between two timber layers?
Furthermore, log houses are common for the houses with the maximum of 2 full floors because of their high placement of more than 15 cm per story. Thus, the occurring forces are within a manageable framework and can be determined sufficiently precisely with the methods of the structural analysis for members in 2D structures. In RFEM/RSTAB, there is an option to define round members in a tapered way for this purpose. Thus, the definition of 2D equivalent systems can be done much faster in RFEM/RSTAB.

There is some information in the given literature source.
