STRAIN GAUGE BASED MICROSENSOR FOR SPATIAL STRESS ANALYSIS IN BUILDING STRUCTURES

Falk Tegtmeier, Manfred Peters
Abstract:
Strain gauges are suitable for stress analysis in buildings due to their high signal resolution. A long-term supervision requires an encapsulated adaptation because of the chemical sensibility of strain gauge applications. The sensor lifetime depends on the encapsulation seal protecting the strain gauge. Therefore, different concepts were examined and adapted to the specific requests in climatic simulation facilities. The mechanical adaptation of the sensor is decisive for its measuring uncertainty. Various concepts were investigated and a process of mechanical distortion of two conical bodies developed such that the useful measuring range covers the range of elastic deformation of construction steels.
