Sažetak
Structural damage detection of a bridge structure using displacement influence lines and displacement influence surfaces is presented in this paper. Numerical testing is carried out for beam and plate-like bridge structures. Imperfections in a structure are related to changes in the static response of the structure. Static methods are used as they are more precise than modal testing, and therefore more attractive than the dynamic methods. Furthermore, displacement influence line can be obtained from measurements at only one point in the structure. In this work, the software "DARK" and "PLOCA" are used (author I. Kožar) for modelling intact and thevarious damaged cases. The displacement influence lines and influence surfaces are calculated for both of these cases and the central difference approximation is used to derive the curvatures from the displacement influence lines and influence surfaces. By plotting the difference in curvature of the displacement influence line or surfaces between the intact and the damaged case, a peak appears at the damaged elements. The aim of this work is to find out a minimal number and the optimal location of the measurement points in the bridge structure that can enable locating the damages reliably.
