Sažetak
In this paper the problem of using strain influence lines to detect and locate structural damages in beam structures is investigated. 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, strain influence line can be obtained from measurements at only one point in the structure as well as deflection influence line. Using strain influence line instead deflection influence line has some advantages: (i) there is no need to derive measured function (the approximation errors are avoid), (ii) the deflection influence lines method gives values at a point while the strain energy method gives values within a segment. The difference in strain influence lines for damaged and intact beam has been used to locate the damage.
