Abstract

In an earthquake occurring directly under a city, such as the Hanshin–Awaji great earthquake, the first axial longitudinal impact induced from the source may create fatal damage to the architectural columns. This phenomenon has been confirmed by a theoretical analysis based on elastic wave propagation in columns fixed at both ends. In this paper, the stress intensification behavior in the columns under axial impact is verified by the high-speed photoelastic experiments in combination with semiconductor strain gage and by the theoretical analysis of the longitudinal stress wave analysis method.
