Abstract
Health monitoring technology has been attracting attention in recent years as a method to evaluate the seismic performance of buildings. This paper introduces a demonstration experiment of an instantaneous seismic capacity evaluation method using accelerometers carried out on a steel reinforced concrete building of the Faculty of Engineering at Hiroshima University. The proposed seismic performance evaluation method was verified by calculating the capacity curve of the building based on the acceleration history of a building during earthquakes as measured by accelerometers, and comparing it with the demand curve obtained from the foundation input acceleration and acceleration records obtained at nearby strong motion observation points. The validity of this evaluation method was demonstrated through comparison of the natural period obtained from the transfer function and the skeleton curve of the capacity curve, and the relationship diagram of the capacity curve and demand curve.
