Description
The BASt load frame is available for testing the structural stability and suitability of engineering structures – especially supporting structures – and for studying the properties of road surfaces. It was established to investigate large-scale structural elements and realistic constructions.
The load frame now makes it possible to apply static loads between 100 and 2,000 kN (app. 10 to 200 t) to a structural element or a system. The master cylinder was additionally fitted with a tool holding mechanism during the course of modernisation. A tandem cylinder can be secured to this mechanism which, combined with a further hydraulic unit, enables dynamic loads of up to 50 kN per cylinder at a frequency of up to five hertz to be applied. In conjunction with this dynamic module it is possible to conduct e.g. tests on the dynamic load of expansion joints, openings and concrete road surfaces.
A test pit made of reinforced concrete (max. depth more than 3 m), is located under the load frame for setting up large-scale trials. It can be sealed off and divided up into individual sections.
Date of construction: 1983, modernised in 2014 and 2015.
