The GIS laboratory comprises four testing halls (GC G0 604, GC H0 672, GC H0 682, GC G0 555), four climatic rooms as well as 3 workshops. The total area of the testing facilities is 830 m2.
The heart of the GIS laboratory is the strong floor, on which a mechanic-type reconfigurable steel system allows for the construction of project-specific test setups. A broad range of servo-controlled actuators are used to apply force- and/or displacement-controlled boundary conditions; a particular feature of the laboratory is its capacities for carrying out low and high cycle fatigue tests.
GIS offers a wide range of optical measurement systems, suitable for measuring 3D displacement fields of specimens of all scales. A large set of universal testing machines (forces from N to MN) are available for material and component testing under uni-axial and multi-axial loading as well as combined mechanical-temperature loading. The workshops offer the possibility to leverage state-of-the-art measuring capabilities in order to conduct unique testing.

Future capacity developments will reinforce the current strengths of the laboratory with regards to ultra low and high cycle fatigue testing as well as testing of materials under multi-axial loading and combined temperature-mechanical loading. A recently completed test rig (Cage) will allow the control of up to 8 simultaneous channels. It will also introduce hybrid simulation capabilities to the laboratory (simultaneous testing of coupled experimental and numerical substructures) through a recently purchased state-of-the-art controller. The supporting servo-hydraulic equipment will be suitable for pseudo-dynamic and highly dynamic tests.
