Low cost health monitoring of cable stayed bridges using synchrosqueezed wavelet transform and nonlinear principal component analysis

Today, health monitoring of structures has been standardized in many countries. Such systems for large and complex structures are equipped and include numerous sensors. Therefore, they are not yet practical in our country due to large final expenses. The main purpose of this paper is to introduce a...
