NON-DESTRUCTIVE STRUCTURAL TEST USING WAVES AND SOFT
COMPUTING. CASE STUDY: PILE INTEGRITY
INSPECTION USING GENETICALLY OPTIMIZED NEURAL NETWORKS
Keywords:
inverse problems, non-destructive testing, wave propagation, pile integrity
testing, island genetic algorithm, neural detectors
ABSTRACT
Non-destructive
testing of structures using wave propagation and reflection and soft computing
for the post-processing of the results is addressed in this contribution. As a
case study, a neural network based scheme and its decision mechanism are
utilized to classify defects in piles. Numerical simulation results are used,
in combination to an island genetic algorithm, for the neural detector
initialization, as well as, for performance validation.

HOW WELL DO SEISMIC
PERFORMANCE ASSESSMENT METHODS PERFORM IN THE LIGHT OF FIELD DATA
Keywords: Damage, performance based seismic engineering,
reinforced concrete buildings, nonlinear capacity estimate
ABSTRACT
The goodness of estimates for regional urban seismic risk for
buildings has not been fully tested in the light of field data. This stems from
a dearth of studies related to how well performance assessment procedures
forecast individual buildings. Three identical buildings were subjected
to strong ground motions over an eleven-year period in Turkey. With extensive
documentation for the input motions and the resulting damages it was possible
to test how well those damages could have been forecast. Analytical studies are
not encouraging.

He earned a PhD in Structural Engineering
form Politecnico di Milano, where he is actually Associate Professor of Theory
and Stability of Structures. As an academic he has published researches related
to several scientific and technical subjects, ranging from theoretical and
computational mechanics to structural dynamics, stability and optimisation.
In the last two decades he also gained a
sound experience as a Structural Designer and Advisor, having been involved in
many relevant building-related and infrastructural projects, and awarded in
several Bridge Design Competitions. He has also a specific skill in Assessment
and Retrofit of existing structures and Historical Buildings.
Since 1999 he is Partner and Principal of the
Structural Engineering firm B&C Associati.
