STUDY ON DYNAMIC BEHAVIOR OF BUILDINGS ON EMBEDDED FILL OR CUT SOIL BASED ON MICRO TREMOR MEASUREMENT

The effects of embedded fill and cut soil on the ground motions as well as on the response of structures supported on the sites were investigated by the micro tremor measurement. The main findings obtained through the study are as follows:1) The predominant frequency measured on the embedded fill site is almost independent on the depth of the fill soil. The amplitudes of the ground motion tend to increase with increase of the depth.2) The effects of soil on the structural response tend to be more pronounced for a structure supported on the embedded fill soil than the structure on the cut soil.
