Services
Our range of services includes the execution of standardized material tests as well as the development of new test setups for special test tasks, which cannot be solved with standardized experiments. We have many years of experience in the fields of destructive and non-destructive material testing. A further focus is on planning, carrying out and evaluating experimental load bearing capacity analyses. Furthermore, our employees
have extensive experience with textile- resp. carbon-reinforced concrete. This applies to standard tests for material characterisation, the production of new components as well as the execution of strengthening work.
The following is an excerpt from our range of services:
Destructive material testing
- For various materials including textile-reinforced concrete: compressive strength; uniaxial, splitting and adhesive tensile strength; modulus of elasticity and Poisson's ratio
- Bending tests
- Working lines, fracture mechanical parameters
- Multi-axial compressive and tensile strength
- Bond tests
- Special tests on test specimens with different geometries and properties
- Static, cyclic, long-term and impact load scenarios
Non-destructive material testing
- Ultrasonic examination
- Rebound values
- Locating of steel reinforcement
- Measurement of forces, displacements, and strains including photogrammetry
- (Video-) endoscopy
- Creep and shrinkage tests
Experimental structural safety analysis of existing structures
Buildings are usually designed for a limited service life and the function of the structure is normally defined precisely at the time of its construction. Over time, there are various influences, such as Increasing traffic load, lack of maintenance, unforeseen environmental influences and associated aging or a planned conversion, to the fact that the current load safety is not known. Unfortunately, there are often no or only insufficient building documents available to statically evaluate the load-bearing capacity. For these reasons, it may be useful in certain cases to determine and evaluate the load-bearing capacity experimentally in order to determine remaining service life or to demonstrate the carrying capacity for conversion.
The range of services offered by the Otto Mohr Laboratory includes:
- Determination of the current stability and serviceability of structures or building parts as a basis for estimating the remaining service life and cost planning
- Investigations on bridges and buildings, incl. listed structures
- Realistic determination of the boundary conditions for a planned change in use of buildings
- Force and displacement measurements
- Vertical (ceilings, beams) and horizontal load scenarios (railings, walls)
