Abstract:

A long term observation on a scaled steel braced frame model with intentionally reduced seismic strength is ongoing since 1983. This paper examines the seismic load effects of two earthquakes observed, which caused moderate damages on the model structure in different manners. A technique of spectral analysis is newly developed to express non-stationary change of seismic damage potential and applied to the two ground motions observed.
