Experimental Methods in Earthquake Engineering

Institution:
IUSS Pavia
Specialization:
EE - Earthquake Engineering
Term:
Fall 2009
Teacher(s):
GIANMARIO BENZONI
Credits:
6
Date (from - to):
11/01/2010 – 05/02/2010

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.
