Abstract
The objective of this project is to
develop a method to detect the damage of
structures. Dynamic tests are performed on
the structure to obtain either the modal data
or dynamic response of the structure. Then,
the Bayesian approach is adopted to construct
the posterior distribution of element
properties based on the modal data or
dynamic response. Taylor’s expansion is
used in the formulation of conditional
probability that is required in the Bayesian
modification. The posterior means obtained
by the Bayesian approach are used as an
indicator of element damages. Numerical
examples are presented to illustrate the
proposed method.
