Abstract
An effective method utilizing the differential evolution algorithm (DEA) as an optimisation
solver is suggested here to detect the location and extent of single and multiple damages in
structural systems using time domain response method. Changes in acceleration response of
structure are considered as a criterion for damage occurrence. The acceleration of structures
is obtained using Newmark method. Damage is simulated by reducing the elasticity modulus
of structural members. Three illustrative examples are numerically investigated, considering
also measurement noise effect. All the numerical results indicate the high accuracy of the
proposed method for determining the location and severity of damage.
