EMI 2011 Pre-conference Short CourseIdentification & Diagnostics in Structural Engineering
Wednesday, June 1st – 9:00 a.m – 5:00 p.m
Dionisio Bernal is a Professor at Northeastern University in Boston. He is the recipient of the Moisseiff Award from the America Society of Civil Engineering (ASCE) for his work on dynamic instability and of the Martin W. Essigmann and the Hayes awards from Northeastern University. His research is in structural dynamics, earthquake engineering and structural health monitoring . He is co-Author of a McGraw-Hill textbook on Reinforced Concrete Design.
1. Linear Systems – State Space and 2nd Order Formulation.
Continuous time, sampled time and discrete time models. Continuous to discrete (c2D) and discrete to continuous (d2C) transfer. Modal model and the physical system matrices. Classical and arbitrary damping
2. Controllability and Observability.
Observability and controllability gramians – use of these concepts in the selection of sensor layouts.
3. Identification – the Eigensystem Realization Algorithm (ERA)
The Observer system, discrete time Markov parameters, balanced realizations
4. Perturbation approach to mode normalization in output only systems
Basic schemes, the projection approach
5. An Introduction to fault detection and localization
The Kalman filter as a fault detector – damage localization
Regular registration is $200 and student course fee is $120. Course fee includes course handout material.
