Tensile membrane structure shape calculated in RFEM, software for static analysis.
RFEM 6 includes the Form-Finding add-on to determine the equilibrium shapes of surface models subjected to tension and members subjected to axial forces. Activate this add-on in the model's Base Data and use it to find the geometric position in which the prestress of lightweight structures is in equilibrium with the existing boundary conditions.
Membrane Roof and Cable Net Structures, Deformation Animation in RFEM with RF-FORM-FINDING Add-on Module.
Compared to the RF-FORM-FINDING add-on module (RFEM 5), the following new features have been added to the Form-Finding add-on for RFEM 6:
- Specification of all form-finding load boundary conditions in one load case
- Storage of form-finding results as initial state for further model analysis
- Automatic assignment of the form-finding initial state via combination wizards to all load situations of a design situation
- Additionally form-finding geometry boundary conditions for members (unstressed length, maximum vertical sag, low-point vertical sag)
- Additional form-finding load boundary conditions for members (maximum force in member, minimum force in member, horizontal tension component, tension at i-end, tension at j-end, minimum tension at i-end, minimum tension at j-end)
- Material type "Fabric" and "Foil" in material library
- Parallel form-findings in one model
- Simulation of sequentially building form-finding states in connection with the Construction Stages Analysis (CSA) Add-On
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
- I would like to calculate and design "temporary structures." What do I need for this?
- How is an inflatable object simulated in RFEM?
- Which Dlubal Software programs are required to calculate membrane and tensile structures?
- I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
- In connection with the calculation according to the large deformation analysis, I get significantly smaller deformations than for the calculation according to the linear static or second-order analysis. How is this possible?
- Are the models and presentations from Info Day 2020 freely available, and can you send them to me?
- Why does the form-finding not work for the "Cable on Pulleys" member type?
- Are the models and presentations from Info Day 2015 freely available, and can you send them to me?
- Why does the command "Calculate all" not calculate the results for load cases with the action category "Form-finding"?
