Abstract: In order to ensure that major construction projects meet the normal use requirements of buildings duringearthquakes, the seismic performance of Guangzhou Baiyun International Airport Terminal 3 was studied. Through theseismic performance design, the elastic performance target of the corolla bifurcated column under large earthquakes was determined. Combined with the multi-point and multi-dimension seismic response analysis of the super-long structure, theinfluence of the traveling wave effect on the main structure was studied and the corresponding strengthening measures weredetermined. The seismic force amplification factor of the side column and the corner column is 1.3, and the center columnis 1.1. The calculation results shows that under the action of 1.5 times the fortification earthquake, the maximum elasticinterstory displacement angle is not more than 1 / 300, which meets the seismic performance requirements for normal useduring earthquakes.
