SHAKING TABLE TESTS AND NUMERICAL ANALYSIS OF STRUCTURAL MODEL OF CHINA PAVILION FOR EXPO 2010 SHANGHAI
The National Hall of China Pavilion for Expo 2010 Shanghai was specially designed with a shape of inverted trapezoid in elevation and local discontinuity of floor slabs in plan. The fundamental vibration mode of this structure is a torsional mode due to the special shape with greater moment of inertia in upper floor,thus resulting in the period ratio exceeding the limit value stipulated in Chinese code. Shaking table tests of a 1/27-scale structural model were conducted to evaluate its overall seismic performance and verify the structural design. The results of the shaking table tests in terms of the global and local responses as well as the dynamic properties are presented. The numerical model of the tested structural model was established by ANSYS program. The dynamic properties and earthquake responses under frequent earthquake with the Chinese intensity of 7 were obtained by elastic analysis. The analytical results agree well with the test results. The shaking table model tests and numerical analysis demonstrate that the designed structural system satisfy the pre-defined performance objectives. To better control seismic damages of the building,some suggestions for improving the design of this structure are also put forward at last.
