Abstract: Urumqi International Airport new T4 terminal building of the reconstruction and expansion project was built withtotal floor area of 504000 square meters. The project has several characteristics such as high seismic fortification intensity,large temperature difference, large wind load and snow load, special site conditions, unique architectural modeling andhigh structural safety requirements. The main structure of the central area is concrete frame struture with seismic isolationtechnology and the roof is a special-shaped long-span steel structure. Some key problems and design measures wereintroduced, including the design of high fill basement and foundation, the structural design of the central area using seismicisolation technology, the structural design of the north-south triangle area using local energy dissipation technology, thedesign of the long-span steel roof structure of the main building. The calculation results show that various correspondingmeasures taken according to the characteristics of the project make the overall structure meet the requirements.

Keywords:Urumqi International Airport; high fill basement; seismic isolation design; local energy dissipation; long-spansteel roof
