Still the change in soil due making new buildings is not very clear. The present study is giving the light on change of soil due to structures and change of structures due to soil or what is named soil-structure interaction. Rivera City is one of the newly generated cities located in Sheikh Zayd City (Figure 1). The natural frequency of vibration of the soil of Rivera city was determined in relatively remote area using Microtremors technique. It was found to be about 10HZ. The same method was used again for determining the natural frequency of vibration empty room buried under the ground lever which was found to be about 5HZ. The dimension of the buried room is 2.5m height, 4.5m length and 3m width. A dynamic analysis model for this buried room was determined using a structural analysis software ETABS v18.1 and was found to be about 5HZ. To study the soil structure interaction a profile was taken starting from the soil and ending over the buried room. The spectrogram analysis method was introduced. The spectrogram is a continuous recording to the change in frequency with time for this profile showed that soil is carrying several frequencies in our case 5,8,12.5, 17.5 and 25 but when the buried room is initiated its resonance frequency is added to the soil. Moreover, after the room was built the spectrogram over the room is filtering the soil frequencies and absorb only the frequencies related to its dimensions in our case 5HZ, 10HZ, and 17.5HZ and make it continuous and clear. The study suggests that initiation of new constructions affect the soil and introduce new frequencies and also the new buildings make filter to the frequencies carried by the soil and show only frequencies related to its properties.
