Experimental Validation Technique for Strain Transfer Characterization of Fibre Optic Strain Sensors
(2011)
Berlin Main Station is the largest multi-level station in Europe. Its daily passenger number amounts to over 300.000. Structures built for such a large number of people require a high-level safety standard. The station was built on the inner city site of the historic Lehrter Bahnhof. The conditions for building and start of operation were challenging by several reasons. The typical sandy ground with a high level of groundwater makes the permanent static stability of such a complex structure difficult. Several completed, ongoing, and planned construction activities in the immediate vicinity of the station influence the ground settlement of the whole area. On basis of the structural design an impact prediction was calculated, which expected certain vertical displacements particularly between the single columns of the outer concrete bridges of the building. These columns support the glass roof construction, which only allows a defined limit of displacement. In order to avoid damage, a concept for monitoring and adjusting potentially occurring displacements was developed for installation at the outer bridges of the station.
Innovative structural damage detection of bridges by least squares adjustment with constraints

The stress vs. strain curve of materials is affected the rate of imposed straining. Among the methods for dynamic testing the technique known as 'split Hopkinson pressure bar' (SHPB) has evolved into the most widely used one to exert high-speed straining. The theory behind it comprises simple equations to compute stress and strain. The reliability of the strain analysis can be assessed by digital image correlation (DIC). The present results indicate that the visually observed strain is smaller than predicted by theory.
Sensing with optical fibres
(2014)
Starting from the first patent of a fibre optic sensor in 1967, fibre optic sensing has become a success story throughout the world. Today, fibre optic point sensors and continuous distributed fibre optics sensor systems allow the measurement of nearly all physical quantities and contribute to higher safety levels in many industrial sectors. Monitoring of pipelines, power cables, lightweight and civil engineering structures, and of ground movements are heading the hit list of applications. Standardization in this field is of paramount relevance and brings to light some of the challenges now faced by IEC SC (Subcommittee) 86C/WG (Working Group) 2: Fibre optic sensors.
