TruDI software, version 2.0 - A Matlab code for structural dynamic identification

This technical report describes TruDI 2.0 (sTructural Dynamic Identification), a Matlab code for structural dynamic identification. TruDI 2.0 is an updated version of TruDI 1.0 and it implements the Enhanced Frequency Domain Decomposition (EFDD), a widely spread non-parametric technique for operational modal analysis and the Complex Mode Indication Function (CMIF) for experimental modal analysis. TruDI allows for calculating the natural frequencies, damping ratios, mode shapes and damped frequencies of a structure, as well as the MPC (Modal Phase Collinearity), MP (Mean Phase) and MPD (Mean Phase Deviation) for each mode.
