Paper Abstract

In this paper, a seismic control method of structures with the tuned liquid column damper (TLCD) is presented by using artificial neural networks. The passive TLCD in the approach is converted into a semi-active variable damping system. The equation of motion for the TLCD-structure interactive system are derived and relevant control algorithm is developed by adjusting the area of orifice-opening in the TLCD and making use of neural networks with BP algorithm. The numerical results of system subjected to earthquake excitations show that the intelligent control approach introduced herein is effective.
