| Research Abstract |
The aim of this study was to develop a system for evaluating seismic capacity of actual structures accurately by identifying the model parameter (mass, rigidity, damping) of structures from the observed waveforms which we obtained by constructing a new observation system using the information technology combined with existing sensors. As a result of consecutive recording of simultaneous, long-term, multi-station observation for a real-size steel frame structure, we found that the effect of the season, temperature or rain is small to the dynamic properties, compared to the effect of wind. Also, after experiments of putting additional mass on one story at a time and observing the change of the properties each time, we found that the actual rigidity and mass was about 50 and 65 %, respectively, of the value obtained from the plan for some stories.
