Structural health monitoring (SHM) systems can perform rapid evaluations of buildings damaged in earthquakes by providing reliable measurements of structural properties and seismic demands. This paper summarizes the output of an SHM system used in earthquake simulation tests of small-scale one-story frame specimens focusing on response spectra and the influence of initial period on estimating seismic demand. The data suggest that calculating linear response using elastic spectra and measured periods reduces error by 350% compared with response calculated using estimated periods.
