Abstract
This paper investigates dynamic characteristics of a base-isolated building affected by partial soil improvement under seismic excitation. An analysis model is made in order to estimate the behavior of such structures under seismic excitations. Comparisons were made between the results from analysis model and observed data. Dynamic properties of impedance and foundation input motion are also analyzed in this paper. It is found that the torsional response is generated due to the partial improved soil. With the increase of the depth and scale of the soil improvement, impedance shows an upward trend, at the same time, foundation input motion decreases.
