Damage Assessment of Plane Trusses By Finite Element Method

Some methods are discussed for damage assessment of trusses. The authors developed one of these methods for suitable use of displacement and strain data. Analytical or experimental data can be used in this analysis. Also, the proposed method is able to use substructure. When the damage occurred in a part of truss, or a specific part of structure is not available, or lack of measurement devices, one can utilize substructures analysis. The damage of several plane trusses are estimated by authorʹs computer program and the results are given in the paper.
