Research Abstract |
Toward effective maintenance of bridge, a lot damage were inflicted on a demolished bridge, step by step, and the ambient vibration was measured in each case to investigate the correlation between damage and changes in dynamic characteristics. Moreover, monitoring method was studied using piezoelectrics for developing bridge damage detection method.
