Dynamic Analysis of Structures Under Blast Loads
In this article, representations of a blast scenario of a remote detonation performed in RF-DYNAM Pro - Forced Vibrations are shown, and the effects are compared in the linear time history analysis.

Considering the Stiffness of Gas Solids in Nonlinear Time History Analysis
The stiffness of gas given by the ideal gas law pV = nRT can be considered in the nonlinear dynamic analysis.
The calculation of gas is available for accelerograms and time diagrams for both the explicit analysis and the nonlinear implicit Newmark analysis. To determine the gas behaviour correctly, at least two FE layers for gas solids should be defined.
- I would like to extend an existing structure with a false ceiling that is not connected to the existing columns. How can I model it?
- For line releases, I obtain the resultants in the horizontal direction, which I cannot understand.
- How can I display wind speeds at a certain height above the ground for a wind comfort analysis?
- Can I also use the wind load generator for open buildings?
- When evaluating the support reactions of a plate supported by line supports, I noticed that the support reaction pz' does not correspond to the shear force and deviates significantly. What is the reason?
- How is it possible to consider the real cross-section geometry of member elements in RWIND Simulation?
- What does the 'Activate Weld Design' option mean in the detailed settings of RF-/STEEL EC3?
- How do I create a frame joint with taper in JOINTS Steel - Rigid?
- Why do I obtain different results for the same end plate joint in RF‑/JOINTS Steel - DSTV and RF‑/JOINTS Steel - Rigid?
- Can I also use RF‑SOILIN to calculate foundation bodies at different foundation heights in a model?
