Abstract

This paper proposed a novel approach to assess the rotational stiffness of structural frame members using nondestructive vibration-based procedure. The procedure is useful for rehabilitation and retrofitting aging structures. Once the vibration signals of a frame member are measured and analyzed, a reverse engineering algorithm could be used to solve the vibration characteristic equation for the stiffness. The required signal conditioner and software are readily available and inexpensive.
