Identification of Parameter of Truss Structure by Limited Static Strain Measurement

Abstract

Structural health monitoring has become significantly important in recent times. Dynamic inverse technique is widely accepted but seems to be complex in case of real-life application. Whereas, the static approach is simple in nature. The proposed paper discusses parameter identification of truss structure adopting static inverse technique in a finite element framework using limited strain measurement. In addition, noise in the measured data, which is quite inevitable in real situations, is also considered to validate its applicability of the proposed model in practical situation. This study further extends in identifying the exact location of the damage in the damaged truss element. The predicated parameters seem to be accurate for various combinations of damage even with noise consideration. The exact damage location in the damaged element is also able to be identified by the proposed method.
