Abstract

Understanding the seismic behavior of buildings during the earthquakes is very important. Microtremor measurements are required to estimate the resonance frequency of soil and buildings . HV spectral ratio technique is widely used in urban environment to assess the fundamental frequency response of the ground. Therefore, the H/V spectral ratio was calculated with this method. The measurements were taken inside the building basement floor, third floor, fifth floor and eighth floor. 150 m on southwest of the building is selected as the garden point. It is noticed that if the number of floors increases, predominant frequencies decrease and H/V ratios increase. The amplitude spectral analysis of the all points was carried out to determinate the spectral characteristics of soil and building. The amplitude spectrums of all data were compared with each other. It points that significant increasing of amplitude values are interested with increasing of the floor numbers. Therefore, the highest amplitudes are obtained on the top floor. The amplitude values of horizontal components are greater than vertical component at the floors 3rd ,5th and 8th. However, we observed similar values at basement point and outside point at all components.
