After successful completion of the course, students are able to…

• describe the physical measuring principles (inductive, piezoelectric, optical) of different sensors and assess their possible applications in relation to structural dynamic measurement tasks.
• explain measurement chains for the determination of time-dependent mechanical quantities and justify the sensible placement of sensors and name necessary additional devices.
• prepare and analyse measurement data digitally and interpret the results.
• carry out concurrent numerical calculations and compare them to the measurement results.

Measurement equipment for recording of time-dependent mechanical parameters (sensors, amplifiers, display of measured data, processing of recorded data). Experimental determination of natural frequencies and damping coefficients considering as example beam- and multistory frame structures by applying piezoelectric accelerometers and force transducers.
