Why Dlubal Software?
Wind Simulation & Wind Load Generation
It's getting windy here! Send your structures to the digital wind tunnel using the stand-alone program RWIND 2. It simulates wind flows around structures, regardless of whether they are simple or complex.
You can easily import the generated wind loads acting on these objects into RFEM or RSTAB and use them for your further calculations.
In the Concrete Design add-on, you can perform seismic design for reinforced concrete members according to EC 8. This includes, among other things, the following functionalities:
- Seismic design configurations
- Distinguishing between ductility classes DCL, DCM, DCH
- Option to transfer a behavior factor from the dynamic analysis
- Checking limit value for behavior factor
- Capacity design 'Strong column – weak beam'
- Design rules for curvature ductility check
- Design rules for local ductility
With the Concrete Design add-on, you can perform the fatigue design of members and surfaces according to EN 1992‑1‑1, Chapter 6.8.
For the fatigue design, you can optionally select two methods or design levels in the design configurations:
- Design Level 1: Simplified design according to 6.8.6 and 6.8.7(2): The simplified design is performed for frequent action combinations according to EN 1992‑1‑1, Chapter 6.8.6 (2), and EN 1990, Eq. (6.15b) with the traffic loads relevant in the serviceability state. A maximum stress range according to 6.8.6 is designed for the reinforcing steel. The concrete compressive stress is determined by means of the upper and lower allowable stress according to 6.8.7(2).
- Design Level 2: Design of damage equivalent stress acc. to 6.8.5 and 6.8.7(1) (simplified fatigue design): The design using damage equivalent stress ranges is performed for the fatigue combination according to EN 1992‑1‑1, Chapter 6.8.3, Eq. (6.69) with the specifically defined cyclic actionQfat.
In the Steel Design add-on , you can apply a value for cold-formed cross-sections according to EN 1993-1-3, which performs the stability analysis and cross-section design according to Clauses 6.1.2 - 6.1.5 and 6.1.8 - 6.1.10.
In the Steel Joints add-on, you can classify the joint stiffness.
In addition to the initial stiffness, the table also shows the limit values for hinged and rigid connections for the selected internal forces N, My, and/or Mz. The resulting classification is then displayed as "hinged", "semi-rigid", and "rigid".
Would you like to calculate curved beams (for example, made of glued-laminated timber)? For this purpose, you can use various section distributions for members:
- Pitched cambered beam with constant height
- Pitched cambered beam with variable height
- Fish beam | Parabolic
In the Steel Joints add-on, you have this option to consider the preloaded bolts in the calculation of all components.
You can easily activate the prestress using the check box in the bolt parameters, and it has an impact on the stress-strain analysis as well as the stiffness analysis.
The ponding load type allows you to simulate rain actions on multiply curved surfaces, taking into account the displacements according to the large deformation analysis.
This numerical rain process analyzes the assigned surface geometry and determines the amount of the rain water drained off and accumulated in puddles (water sacks) on the surface. The puddle size then results in a corresponding vertical load for the structural analysis.
For example, you can use this feature in the analysis of approximately horizontal membrane roof geometries subjected to rain loading.
Several modeling tools are available for elements in building models:
- Vertical line
- Rectangular floor
- Polygonal floor
- Rectangular floor opening
- Polygonal floor opening
This feature allows you to define the element on the ground plane (for example, with a background layer) with the associated multiple element creation in space.
You can simulate the static friction effects between two supporting components along a line using the "Friction" nonlinearity in the line release type.
The Concrete Design add-on allows you to design fiber-reinforced concrete components according to the guideline "DAfStb Steel Fiber-Reinforced Concrete".
You can use this option for the design according to EN 1992‑1‑1. The design according to the DAfStb guideline is carried out once the concrete of the "Fiber Concrete" type has been assigned to the reinforced structural component.
