CASE STUDIES FOR A LARGE-SCALE DOME STRUCTURE USING HIGH-STRENGTH STEEL AND SEISMIC ISOLATION

Abstract

This paper reports the result of case studies for a large scale dome structure with a diameter of approximately 300m. Schematic designs of a total of four domes are conducted to quantitatively evaluate the advantages of using high-strength steel and/or seismic isolation. It is shown that the unit structural weight of the dome with high-strength steel and base isolation can be as small as half of the one without the two.
