Paper Abstract

This paper presents a new methodology that is built upon existing hardware such as shaker force generator and accelerometers that are both portable and convenient to use for a variety of civil and mechanical structures. Our key idea is to use a moving load that is placed successively at a number of locations on the structure, and measure the corresponding frequency responses. These frequency response measurements will then be used to extract the structural properties. Our new methodology so called mass response method enables the direct extraction of the equivalent stiffness and mass of the critical members of a structure without using a priori information of the structure. A number of case studies are carried out to demonstrate the accuracy and efficiency of its usage in structural health monitoring applications. Furthermore, the uncertainty introduces to this methodology is also investigated and discussed.
