Dynamic Structural Properties of Cable‐Stayed Tampico Bridge

Experimental evaluation of the dynamic properties of a wharf structure

“…From the analysis of the response decay it is possible to determine the dynamic properties of the structure. This type of test presents several difficulties when applied to large existing structures in operation [7,8]. The principal difficulty is related to the application of the load, which requires a strong support point and an accurate determination of the load magnitude to prevent damage to the test structure.…”

Dynamic characterization and damage detection in the I-40 bridge over the Rio Grande

“…Difficulty was had in determining damping ratios, because the small-valued damping ratios were very sensitive to the non-stationary nature of the ambient vibrations and other parameters. Muria-Vila. et al (1991) experimentally determined frequencies and mode shapes for a 3-span cable-stayed bridge based on traffic and wind induced excitations.…”

Impacts of Epistemic (Bias) Uncertainty on Structural Identification of Constructed (Civil) Systems

“…Experimental results compared well with analytical predictions (except for torsional modes) and the authors noted strong coupling between vertical and horizontal modes. Using both step-relaxation and ambient excitation Muria-Vila et al (1991) conducted vibration testing on a three-span cable-stayed bridge. Results indicated good agreement between controlled and ambient excitation tests.…”
