In order to evaluate the effect of the size of building and the site soil condition on the first mode's natural period and damping ratio, the results of the microtremor measurements of 14 buildings located in the Higashiyama campus of Nagoya University are analysed. The selected buildings have different number of stories and foundation size. Also, they have been constructed on different parts of the campus with different soil conditions. So, it is possible to estimate the effect of height and aspect ratio on the dynamic properties of structures as well as the effect of Soil-Structure Interaction (SSI). As the evaluation method, the curve fitting method for the observed transfer functions (Hv estimation) as well as the Random Decrement (RD) method for the generation of free vibration motion are used. Also investigated is the variation of the dynamic characteristics of a 10-story building in the different stages of construction.
