Structural Health Monitoring Using Wireless Technologies: An Ambient Vibration Test on the Adolphe Bridge, Luxembourg City

Figure 7

Example of the derivation of the modal shapes (transverse component, left side of deck) of vibration for the fundamental mode of resonance (upper left, red) and the three higher modal frequencies presented in Figure 6(b) and listed in Table 1. For each modal frequency, each individual line represents the modal shape derived from a one-minute time window. More details on the derivation are given in the text.
