Study on Energy Dissipation of Shenzhen Baoan International Airport T3 Terminal
The main structure of Shenzhen Baoan International Airport T3 Terminal uses reinforced concrete frame and the steel roof is free-form surface. The main concrete structure which is about 1038 m from north to south, and 588 m from East to west, is currently one of the largest Terminal in China. Because the Concourse is very long, the temperature force is relatively large when the bearing is hinged. In order to release the force, the spring bearings are set up along the length to Concourse. However, the displacement increases under earthquake because of the reduction of the stiffness. The speed-related viscous dampers are placed near the strengthened truss for limiting the seismic displacement. However, the damper parameters can be obtained by computing several times in practical engineering. It needs a long period to select the damper parameters especially for complex structures. So this paper takes Shenzhen Baoan International Airport T3 Terminal Cross Concourse as the research object, use the viscous damping theory, determine the additional damping ratio from the perspective of response spectra and the nonlinear damping parameters from the energy point, find a reasonable, fast method to set the damping parameters.
