Learn how to optimize concrete shells using various form finding techniques.
What you'll learn
Description
Why take this course
In this course, Judyta Cichocka teaches you more advanced uses of
Karamba 3D, a parametric engineering plugin for Grasshopper. In this
course, you will explore strategies for the design, form-finding, and
optimization of concrete structures.
The course is intended for architects and engineers interested in
structural art, form-finding, and computational methodologies for the
design of concrete structures. It's recommended to have prior
knowledge of Grasshopper and Karamba3d. However, it is possible to
complete the course without them. This course will introduce students
to the concept of structural art and the creativity of structural
design.
After the course, students understand the concept of topology
optimization and strategies for form-finding.
Learn why Karamba 3D is a powerful structural engineering plugin
Karamba3D is a Finite Element program like many others. However it has
advantages over these in several important respects: It is easy to use
for non-experts, has been tailored to the needs of architects and
engineers in the early design phase. Karamba3D is fully embedded in
the parametric environment of Grasshopper. This makes it easy to
combine parameterized geometric models, finite element calculations,
and optimization algorithms like Octopus or Galapagos.
"Karamba 3D is an easy to use software for non-experts and has been
tailored to the needs of architects and engineers in the early design
phase"
Improving your parametric engineering skills with Karmaba 3D greatly
improves the efficiency to cycle through structural options and quickly
check the structural performance of your project.
Learn how to use evolutionary topology optimization of concrete
structures
In the first lessons, you will work on an example project called
the Mao Haus by AntiStatics Architecture. You will be designing
and optimizing the shape of this free form facade using Karamba.
Before jumping into the example project you will go over some
simple cross-section optimization of timber and steel trusses.
Learn to generate funicular shapes using large deformation
analysis
In the next lessons, you will be designing and optimizing
funicular concrete shells. The Aichtal outdoor theater by Heinz
Isler Architects will be used in this example. After a quick
introduction, you will learn to analyze the force lines going
through the concrete shell.
Learn to check using Finite Element Analysis that the structure is
in compression only
After being more familiar with the design of concrete shells, you
will learn how to analyze and optimize shells to be compression
only. You will understand where the maximum principle dresses are
located, bending moments, and normal forces.
Learn how to apply multi-objective optimization for fabrication
and improve its overall performance
The last part will focus on how to use multi-objective
optimization to create constructible concrete shells. Los
Manantiales Restaurant by Felix Candela will be used in this
example. You will learn how to create a hyperbolic paraboloid
surface and how to set up an FE model in Karamba to do a
structural analysis and optimize the result.
