The course is intended as an introduction of graduate students to the experimental techniques and measurements employed in engineering and specifically in earthquake engineering. The course content comprises:
Basic knowledge for designing an experimental campaign, scope of the testing, etc.
Principles of designing test set‐ups, planning and preparation.
Dimensional analysis, similitude requirements, true and distorted models, scaled tests.
Testing methods: static, dynamic, pseudodynamic, artificial excitation
Servo‐hydraulic testing systems: loading systems (actuators, servovalves, pumps), system control theory
Sensors. Principles of operation, sensor characteristics, sensor mounting, converters
Data collection, data acquisition (hardware and software), data analysis and presentation.
Structural monitoring, in‐situ vibration testing, Lab exercises, homework and example experimental studies.
