Abstract

In this paper, the seismic response of base-isolated liquid storage tanks subjected to real and simulated near-fault ground motions is investigated. It is assumed that the tanks are seismically isolated by single surface Concave Sliding Bearings (CSB) with different isolation periods. For the input data, the recorded and simulated ground motions having pulse type characters and their dominant waveforms are considered.
