Structural health monitoring technique was applied to an aged arch dam, where long-term continuous observation of ambient vibration/seismic motion was performed over a sp [...]

To evaluate seismic safety of an aged concrete arch dam, present dynamic properties have been continuously measured by ambient vibration test for more than one year, whic [...]

Transition of dynamic characteristics, such as natural frequency, damping ratio, and mode vectors, was investigated by using a long-term ambient vibration test on a low-r [...]

A new system identification procedure, named as “Adaptive Forward-Backward Kalman Filter (AFB-KF)”, is developed to estimate natural frequency transition of a buildin [...]

Changes of modal parameters of a full scale 4-story steel building due to construction progress or seismic damage are evaluated in the shaking table test of the 2007 E-de [...]
