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.

Lecture Title: Damping models in continuum methods for dynamic analysis of buildings

Abstract:

 

ABSTRACT

Condensed 1D continuum models, called "Replacement Beams" (RBs), often provide an useful tool to capture basic features of the static response of a wide class of regular buildings, among which high rises. Despite potential capabilities of RB models, up to now few attempts have been done toward their adoption in dynamical calculations considering structural damping, as well as in modelling passive-damping devices, more and more frequently provided in order to attain comfortable, robust and resilient structural arrangement in hazard prone conditions with sustainable constructional indexes and material savings. The introduction of simple damping mechanisms and an overview on potentialities in passive damping optimization analysis are therefore briefly outlined in order  to show potentialities of these approaches in producing feasible dynamic estimations.
