Health monitoring of slabs is generally carried out on the basis of their stiffness. So, in the first report, the method to identify spring constant, mass and damping coefficient separately by wavelet transform of an excitation force and response accelerations was proposed and examined. To develop the research, the method to identify spring constant is, in the second report, theoretically investigated on condition that the measured data of the excitation force and the response acceleration include noises. The method is to find the specific value of constant α in the analyzing wavelet which gives the most reliable value of the spring constant according to the graphic shape of the relation between identified mass and constant α. In this report, it is examined to expand the method to five degree-of-freedom models.
