Damage Detection on Steel Plane Trusses via Harmony Search Algorithm

Öz

A damage detection study is presented on steel plane truss structures via harmony search algorithm which is one of the basic metaheuristic methods. This algorithm method mimics better musical harmony procedures. Optimum solutions are carried out by a harmony memory matrix consisting of a predetermined number of solution vectors. Scenario damages are considered on truss models. The locations of the damages are tried to determine by using the dynamic parameters. To obtain damage locations, a program based on the finite element method is coded in MATLAB programming. The dynamic parameters of damaged models are obtained by SAP2000 software.  By using MATLAB programming, the scenario damage locations considered in SAP2000 programs are tried to determine by approaching the dynamic values of the damaged model as a result of a series of iterations. The results are presented by tables and figures. The results show that scenario damages on truss models are successfully detected by using dynamic parameters in MATLAB programming.
