ABSTRACT
The China Pavilion as one of the core buildings for 2010 Shanghai World Expo’s is a steel-concrete composite structure. The main body of the structure consists of four 18.6m × 18.6m reinforced concrete tubes with a distance of 51.3m between centers of the tubes. The experimental study and numerical simulation indicated that the first vibration mode of the structure is integral torsion. It is necessary to investigate the structural response under the inconsistent excitation considering the multiple tube arrangement and major span. The traveling wave effect for China Pavilion under four seismic waves is numerically simulated using the advanced finite element analysis program ANSYS. The seismic response to inconsistent excitation is calculated using time-history method. In comparison with that to consistent excitation, the present results show that the torsional effect increased obviously when traveling wave effect is taken into consideration.
Keywords: Multi-input excitation, Seismic response, Time-history seismic analysis, Travelling wave effect.
