Beam Displacement – Karamba3D

Input curves and Analyze as a Truss

Beam Displacement, Beam Forces, Beams, Modify Elements

The team at the University of Virginia has created a series of Karamba3D examples to guide users through several workflow processes.

Each example is thoroughly explained and the geometry is internalized to run without supporting Rhino files. Input new rhino geometry into the Grasshopper definitions to see how the geometry performs.

Difficulty: Simple
This example introduces Karamba3D input and analysis. while demonstrating support types and axial restriction on beams.

Change slider that controls loads and notice the behavior of the hinge and roller supports as truss deflects.
Toggle the “modify element” component to change beams to axial-only loads; hinged joints
Turn control points on in rhino to adjust the geometry of the truss

This example uses Karamba3D 1.3.3.

Export a Simple Parametric Truss to Revit with Rhynamo

Beam Displacement, Beams, Dynamo, Optimization, Revit, Rhynamo

In a simple 3 part tutorial, Junghwo Park explains how to create a single truss in Karamba & Grasshopper and then exporting the geometry into Revit using Dynamo BIM & Rhynamo.

The final tutorial explains how to export the truss that was created in Grasshopper and Karamba and import this into Revit. See Tutorial 1 & 2 – Simple Parametric Truss in Karamba.

Part 3 – Export to Revit

Get the reference files here: KarambaToDynamoBIM_SingleTruss

These tutorials use Rhinoceros (Version 5 SR12 64bit), Grasshopper (0.9.0076), Karamba (1.1.0), Revit (Version 2016) & Rhynamo

Simple Parametric Truss

Beam Displacement, Beams, Cross Section Matcher, Optimization

In a simple 3 part tutorial, Junghwo Park explains how to create a single truss in Karamba & Grasshopper and then exporting the geometry into Revit using Dynamo BIM & Rhynamo.

The first tutorial explains how to set up a truss parametrically and subsequently the following video shows how to analyze the structure in Karamba and then optimize the truss using Galapagos. See Tutorial 3 – Export a Simple Parametric Truss to Revit with Rhynamo

Part 1 – Set up the truss parametrically

Part 2 – Integrate the Truss into Karamba

Get the reference files here: KarambaToDynamoBIM_SingleTruss

These tutorials use Rhinoceros (Version 5 SR12 64bit), Grasshopper (0.9.0076) & Karamba (1.1.0).

Introduction – Beam Grid

Beam Displacement, Beam Forces, Beams, Cross Section Optimizer

Blue Clements (UVa M’Arch 2017) has made a series of Karamba Introductory tutorials as part of the Parametric Stuctural Design courses at the University of Virgina headed by Jeana Ripple.

The six part tutorial explains how to set supports, loads, assign cross sections, optimize cross sections and then evaluate the results.

Get the definition here: TU_Intro_BeamGrid.gh

These tutorials use Rhinoceros (Version 5 SR12 64bit), Grasshopper (0.9.0076) & Karamba (1.0.5) where Point Loads, Gravity, etc are separated into different components. The source definition has been created with Karamba 1.1.0 where all Loads are integrated into one component.
