Why Dlubal Software?
Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
With the view option Camera Fly Mode, you can fly through your RFEM and RSTAB structure. Control the direction and speed of the flight with your keyboard. Additionally, you can save the flight through your structure as a video.
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
- Available for cold-formed L, Z, C, channel, top-hat, and CL sections from the cross-section database, as well as for cold-formed, non-perforated SHAPE-THIN 9 cross-sections
- Determination of the effective cross-section considering the local buckling and the distortional buckling
- Cross-section ultimate limit state, stability, and serviceability limit state designs according to EN 1993‑1‑3
- Design of local transverse forces for webs without stiffening
Since RF-/STEEL Cold-Formed Sections is fully integrated in RF-/STEEL EC3, the data is entered in the same way as for the usual design in this module. It is only necessary to select the design option for cold-formed cross-sections in the Details dialog box.
The design results are displayed in RF-/STEEL EC3 in the usual way.
Among other results, the corresponding result windows include the effective cross-section properties due to axial force N, bending moment My, bending moment Mz, internal forces, and design summary.
There is a known complexity of calculating footfall response on irregular floors or staircases of any type. Footfall Analysis uses the RFEM model and the modal analysis results of RF-DYNAM Pro - Natural Vibrations to predict the vibration levels at all locations on a floor. A rigorous analysis method is essential to enable an accurate investigation of the dynamic behavior of the floor.
The software incorporates the most up to date analysis procedures allowing the user to select between the two most used calculation methods available, namely the Concrete Centre Method (CCIP-016) and the Steel Construction Institute Method (P354).
- Footfall Analysis links with RFEM, using its model geometry, so that the user is not required to create a second model specifically for footfall analysis
- Allows the user to analyze any type of structure for footfall analysis, irrespective of the shape, material or use
- Quick and accurate predictions of resonant and impulsive (transient) responses
- Cumulative measurement of vibration levels – VDV analysis
- Intuitive output enabling the engineer to improve critical areas in a cost-effective way
- Pass/fail limit check in accordance with BS 6472 and ISO 10137
- Available excitation forces: CCIP-016, SCI P354, AISC DG11 for floors and stairs
- Frequency weighting curves (BS 6841)
- Quick investigation for full model or specific areas
- Vibration Dose Analysis (VDV)
- Adjusting the minimum and maximum walking frequency as well as the walker’s weight
- User-defined input damping values
- Varying the number of footfalls for resonant response, user input or software calculated
- Environmental response limit based on BS 6472 and ISO 10137
- Overall maximum response factors and critical nodes
- Resonant analysis (maximum response factor, RMS acceleration, critical node, critical frequency)
- Impulsive (transient) analysis (maximum response factor, peak acceleration/velocity, RMS acceleration/velocity, critical node, critical frequency)
- Vibration dose values for both resonant and impulsive analyses
- Response factor vs walking frequency
- Mass participation vs eigenmodes
- Velocity time history
With the activated option "Topology on form-finding shape" in the Project Navigator - Display, the model display is optimized based on the form-finding geometry. For example, the loads are displayed in relation to the deformed system.
When you start the analysis in the interface program, a batch process starts that puts all member, surface, and solid definitions of the RFEM/RSTAB model rotated with all relevant factors in the numerical RWIND Simulation wind tunnel, analyzes the model, and returns the resulting surface pressures as FE node loads or member loads to the respective load cases in RFEM and RSTAB.
These load cases containing RWIND Simulation loads can be calculated and combined with other loads in load combinations and result combinations.
