“…Similarly, the obtained reconstruction responses are averaged. Figure 18 shows measurement strain data and reconstructed strain responses of the 5-th optical fiber measurement point in the first 4 s. From Figure 18, it is observed that increasing the number of the measurement points has trivial From Figure 18, it is observed that increasing the number of the measurement points has trivial effects on the accuracy of the reconstruction results, which is consistent with the simulation results in [14]. However, in the real situation, increasing the number of measurement points can improve the robustness of the data acquisition in case of measurement points are broken or record incorrect data.…”

“…The reconstructed strain response at the 15-th measurement point and the theoretical result are compared in Figure 17a. Figure 17b boundary/end effect in EMD method [14], which has been widely discussed as the intrinsic weakness of EMD. One of the possible solutions for this problem is using the mirroring method to extend signal envelopes from both ends, thus effectively eliminating end effects.…”

“…Data recovery can be considered as a remedy when the data loss occurs. To address the lost data recovery issue in SHM, approaches based on the finite element model (FEM) have been proposed . Other than those model‐based methods that demand an accurate FEM, response recovery conducted directly from the measurements is more attractive and applicable for large‐scale infrastructure with numerous uncertainties.…”
