Shaking table test research on the frame-corewall structure with strengthened storeys and sloping core for Jinan Greenland Shandong IFC
The main tower of Jinan Greenland Shandong IFC is designed and tested on a shaking table with a scale of 1:40.The tower is 428m high with seismic precautionary intensity of 7 degree.The structural system consists of steel reinforced concrete frame columns and reinforced concrete corewalls.Ring trusses are located in the middle zone while outrigger trusses,ring trusses and sloping core are concentrated in the high zone.The key points of test design,such as the selection of similarity ratio,the simplification of test model,and the layout of measuring points are introduced.Furthermore,the test results of model damage,natural vibration characteristics,acceleration,displacement and dynamic strain are listed.The results correspond well with the analysis data,indicating that the structure design meets the expected requirements.The floors with both outrigger trusses and sloping core and floors above are seismic weak areas where it is recommended to take into account seismic strengthening measures further.
