Effects of Features of Ground Motion on Structure of Constructions During Earthquakes

Earthquakes are very strong oscillations of the ground that cause foundation movements of the building. Therefore, the ground movements during an earthquake is one of important factors affecting the structures of buildings that are subjected to earthquake loads. Among various indices of earthquake ground motion, the maximum amplitude, the duration of strong motion and the frequency of oscillation play important roles in earthquake resistant design of buildings. In this paper, the author applies the time-history method to evaluating the responses of characteristics of ground motion to building structures. The earthquakes with different amplitudes and durations of strong motion are surveyed
