Create your first FEM-Design objects through the FEM-Design API for Grasshopper

Create plates

Rhino geometry and Grasshopper node graph:

• geometry.3dm
• createPlates.gh

Tasks:

• Try to run the Grasshopper component graph to open the model in FEM-Design.
• Try to change the material from "C30/37" to for example "C20/25".

Relevant actions and methods:

• MaterialDatabase.Default
• Material.GetMaterialByName
• Slab.Plate
• Model.Create
• Model.Open

Add supports

Rhino geometry and Grasshopper node graph:

• geometry.3dm
• addSupports.gh

Tasks:

• Try to run the Grasshopper component graph to open the model in FEM-Design.
• Try to change the line support to type "Rigid".

Used components:

• LineSupport.Hinged

Add loads

Rhino geometry and Grasshopper node graph:

• geometry.3dm
• addLoads.gh

Tasks:

• Try to run the Grasshopper component graph to open the model in FEM-Design.
• Try to increase the load intensity to 10 kN/m² in the negativ global Z-axis.
• Try to change the name of the load case.
• Try to set a comment to the load.

Relevant components:

• Force.Define
• LoadCase.Create
• SurfaceLoad.Uniform

Run analysis

Rhino geometry and Grasshopper node graph:

• geometry.3dm
• runAnalysis.gh

Tasks:

• Try to run the Grasshopper component graph to run the analysis in FEM-Design.
• Try to run the analysis but close FEM-Design when finished.
• Try to run a load combination calculation instead of a load case calculation.
  • In order to do this you have to create a load combination in the component graph and add it to the model.
• Try to set creep and shrinkage to concrete material of plates.
• Try to prepare mesh and change the average element size.

Relevant components:

• Slab.AverageSurfaceElementSize (optional)
• Analysis.Define
• Model.RunAnalysis

Add reinforcement

Rhino geometry and Grasshopper node graph:

• geometry.3dm
• addReinforcement.gh

Tasks:

• Try to run the Grasshopper component graph to open the model in FEM-Design.
• Try to change the diameter of the rebars
• Try to have different spacing in x and y direction.
• Try to add top reinforcement

Relevant components:

• Wire.Define
• Straight.ReinforcementLayout
• SurfaceReinforcement.BySurface
• SurfaceReinforcement.AddToSlab

Run RC design calculations

Rhino geometry and Grasshopper node graph:

• geometry.3dm
• runRcDesign.gh

Tasks:

• Try to run the Grasshopper component graph to run the design calculations in FEM-Design.

Relevant components:

• LoadCombination.Create
• LoadCombination.SetCalculationParameters
• Design.Define
• Model.RunRcDesign
