Thạc Sĩ Structural Design of a Seismic Isolated Building with a Guyed Tower

ABSTRACT
​

A large seismic isolated telecommunications building with a guyed mast
tower was planned to be constructed upon liquefiable subsoil. The foundation and
superstructure have to be designed taking soil condition into account. In order to
penetrate to the firm layer and to establish rigidity to the soft soil layer, a continuous wall
pile system was adopted. For seismic analysis, seven seismic waves were used to carry
out the dynamic response. The results showed a prominent response of the structure on
the higher modes for the site wave. For reducing this response, viscous wall dampers
were installed in the building. Thus the safety of the structure and the realization of the
project was achieved by the application of various structural means such as, continuous
wall piles, seismic isolators, viscous dampers and by conducting thorough seismic
analysis.
