Authors: Jafar Sadak Ali
Abstract: Condition monitoring of structures is significantly important from the safety and
durability consideration. Parameter identification and subsequent damage detection
techniques, using inverse static or dynamic approaches, are important tools to improve
the mathematical models for monitoring the condition of structure. However, noise in the
measured data might lead to unreliable identification of damage in a structural system.
The measurement of static and dynamic responses at all degrees of freedom of a structure
is also not feasible in practice. Five different numerical models for damage detection of
structures are developed for condition monitoring of truss, beam and framed structures in
the framework of finite element model with limited static or dynamic responses. The
structural properties viz. axial rigidity and bending rigidity are identified at the element
level in the updated models of the structural system. Damage at the element level is
identified, by comparing the identified structural parameters of the updated model of the
system with those of the undamaged state. Proposed numerical models are suitable for
practical problem, as it is able to identify the structural parameters with limited static and
modal data of first few modes experimentally measured at selected degrees of freedom.
Different numerical examples with various damage scenarios are explored to demonstrate
the applicability of the proposed models. The models are able to identify the structural
damage with greater accuracy from the noisy dynamic responses even if the extent of
damage is small. Experimental validation on simple cantilever beams and portal frames,
establish the potential of the proposed methods for its practical implementation.
