Wind Loads on Duopitch Roof Building
Verification Example
This verification example compares wind load calculations on a duopitch roof building by means of the ASCE 7-16 standard and by means of CFD simulation in RWIND Simulation. The building is defined according to the sketch and the inflow velocity profile taken from the ASCE 7-16 standard.

Punching Shear Design in RFEM 6
The punching shear design, in line with EN 1992-1-1, should be performed for slabs with a concentrated load or reaction. The node where the design of punching shear resistance is performed (i.e., where there is a punching problem) is called a node of punching shear. The concentrated load at these nodes can be introduced by columns, concentrated force, or nodal supports. The end of the linear load introduction on slabs is also regarded as a concentrated load and therefore, the shear resistance at wall ends, wall corners, and ends or corners of line loads and line supports should be controlled as well.
Computation Kernel with Multi-Core Processor Technology
The calculation is now optimized utilizing a multi-core processor technology. It enables parallel calculations of linear load cases and load combinations by several processors without additional demands on the RAM: The stiffness matrix has to be created only once. Thus, even large systems can be calculated with the fast direct solver.
For models where many load combinations have to be calculated, several solvers (one per core) are started in parallel. Each solver then calculates a load combination. This leads to a better utilization of the cores.
The development of the deformation is displayed in a diagram during the calculation. This allows for good assessment of the convergence behavior.
- Is the Gust-effect (G or Gf) from the ASCE 7-16 Sect. 26.11 considered in RWIND Simulation?
- I would like to enter a large spring constant. Is it possible?
- I would like to perform punching design of a floor slab. I have selected nodes for the design, but they are marked as invalid. Where did I make a mistake?
- How can I define an FE mesh refinement in RFEM 6? In RFEM 5, this was available in the Data navigator.
- Is it possible to display the deformation analysis of a surface (limit 0.5‰)?
- Is it possible to design single-layer reinforced surfaces with RFEM 6?
- How do I perform stability analysis to determine the critical load factor in RFEM 6?
- How can I optimize cross-sections within the steel design?
- Can I switch the required reinforcement in the result tables from "mesh nodes" to "grid points?"
- In RFEM 6, I am looking for the line releases known from RFEM 5. Are they no longer available in RFEM 6?
