Karamba 1.2.2

The latest release of Karamba is now available!

Not only is the solver twice as fast and uses up less memory than version 1.2.0, it contains new features such as the BESO for Shell and improved solution procedures. See the complete list of new features and bug-fixes.

Read the Manual for Karamba 1.2.2.


White Noise - Salzburg Pavilion

The architectural concept is based on a theme that is self-evident in architecture as well as music – rule and variation. Other than conventional design processes that develop forms that are then split up into buildable parts, the adaptive design process starts with a simple base element, a possible range of rules for accumulation and the definition of the targeted architectural effects.


Active Energy Building

The Active Energy Building in Vaduz introduces a novel system of efficient and economic, yet architecturally intriguing bearing structures for housing units. Instead of a traditional approach based on a regular grid of straight columns, inclined columns were introduced that drive through the buildings volume, constituting a symbiosis of functional and architectural parameters.

CIAB Pavilion

The pavilion was designed by Zaha Hadid Architects London for the China International Architectural Biennal. It reinterprets Felix Candela’s works with complementary hypar shells, which are both highly structural and sculptural. As a concept contrasting the originals, the optimal structural logic was partially broken by linking the three parts in the middles of their surfaces, not at the edges.

Dawang Mountain Resort

The COOP HIMMELB(L)AU concept for the Deep Pit Snow and Ice World project engages the existing deep pit, recognizing both its cultural heritage and natural beauty. The roof of the Ice World and its base are freeform geometries with a large span. In order to fulfil design criteria and the requirements for an efficient load bearing behaviour, a form finding process controlled by an genetic optimization algorithm was used to define the global shape.

Karamba is a parametric structural engineering tool which provides accurate analysis of spatial trusses, frames and shells.

Karamba is fully embedded in the parametric design environment of Grasshopper, a plug-in for the 3d modeling tool Rhinoceros. This makes it easy to combine parameterized geometric models, finite element calculations and optimization algorithms like Galapagos.

Karamba is being developed by Clemens Preisinger in cooperation with Bollinger-Grohmann-Schneider ZT GmbH Vienna. Its dissemination is a team effort. We are an interdisciplinary team of architects and structural engineers who use Karamba in our daily office work at Bollinger-Grohmann-Schneider. We provide Karamba and Grasshopper related workshops. For requesting a Karamba workshop please write us an email at [email protected].
