Surfaces in building models can be of many different sizes and shapes. All surfaces can be considered in RFEM 6 because the program allows to define different materials and thicknesses as well as surfaces with different stiffness and geometry types. This article focuses on four of these surface types: rotated, trimmed, without thickness, and load transfer.
The SHAPE‑THIN stand-alone program determines the characteristic values and stresses of any thin‑walled cross‑sections. Graphic tools and features allow for modeling complex cross‑section shapes. In addition to the graphical input, it is also possible to enter the data in tables. As an alternative, you can import a DXF file and use it as a basis for further modelling. Also, each cross-section can be entered using the cross-section library of Dlubal Software and combined as a part with the user-defined elements.
