Center for Light and Environmentally-Friendly Structures ZELUBA®

The Fraunhofer WKI's ”Center for Light and Environmentally-Friendly Structures ZELUBA®” is located on the campus of the Technische Universität Braunschweig and is closely connected to the “Institute of Building Materials, Concrete Construction and Fire Safety“ at the university. At the ZELUBA®, the Fraunhofer WKI focuses on the research and development of light and hybrid materials and structural elements including their environmental and fire performance.

Equipment

Around 1700 square meters of laboratories and offices are available for the execution of research contracts.

The structural testing laboratory is equipped with a shaking table (MTS 1.5 m Uniaxial Seismic Simulator) which is furnished with the state-of-the-art optical DIC system. Further items of equipment include an electrodynamic shaker, a large pendulum test stand for impact experiments, climate chambers, test stands for the investigation of the load-bearing and deformation behavior of components, and other facilities. In addition, diverse testing devices for material analysis and testing will be available, including an atomic force microscope (AFM), a dynamic mechanical thermal analysis instrument (DMTA) for the testing of heterogeneous materials, and further specialized equipment are available.

Future-oriented building

Correspondent to the research at the ZELUBA®, the focus during the planning phase was directed at a modular construction method and the utilization of renewable raw resources in combination with conventional materials. A total of 39 workplaces are distributed throughout the building.

Foyer

Structural testing laboratory

The testing laboratory is a single-bay timber structure braced by steel elements and cables.

 

 

Office and laboratory building

The three-story building is a hybrid construction of reinforced concrete and laminated timber. This future-oriented construction method combines the advantages of the two materials in a very efficient way. The building provides space for staff offices, meeting rooms and laboratories.

 

 

Foyer

A filigree reinforced concrete structure connects the structural testing laboratory with the office and laboratory building. The main entrance to the ZELUBA® and a seminar room are situated here.
