Abstract

Building damage assessment soon after a seismic event is a very significant issue. At present, the sensor implementation of all the floors of a building with not a few stories is not realistic. This paper proposes a framework of estimating all the story responses at about 11-15 story building only with the data of a limited number of accelerometers. Based on cubic spline interpolation, the framework is constructed with the setting of the boundary conditions at the building top and base. The validity of the framework is demonstrated utilizing E-Defense shake table test data.
