Main structural design on main building of Taiyuan Wusu International Airport Terminal 3
Taiyuan Wusu International Airport Terminal 3 project is located at a site with high seismic fortification intensity and complex geological conditions.The main building of Terminal 3 adopts a hybrid structure consisting of a lower concrete structure and a large-span steel structure for the roof.There are exceeding code limitation situations such as local conversion,irregular torsion,column penetration,and steel roof crossing over the lower concrete structure monomer to form a conjoined body.The foundation design and the energy dissipation and seismic reduction design of the lower concrete structure of the main building of Terminal 3 were introduced,including the foundation treatment of local liquefaction sites,the response of penetration of pile with hammer blow to the soil layer with hard laminated interlayer,the horizontal bearing capacity test of pile foundation considering the effect of the pile cap,and the selection of seismic reduction and isolation schemes.The influence of uneven arrangement of viscous dampers under the functional constraints of the Terminal 3 on the seismic reduction effect was discussed,which can provide reference for the design of similar projects.
