SHAKING TABLE TEST STUDY OF A HIGH-RISE BUILDING BEYOND THE CODE-SPECIFICATION

摘要

The building 1-3 in A2 block developed by Wuhan Shimao Group is a high-rise residence with 56 stories. It has a T-type plane and a total area of 65698m~2. The building height is 179.6m, beyond the restriction specified by the Technical Specification for Concrete Structures of Tall Building (JGJ3-2002). To investigate its seismic performance under earthquake, a shaking table test for its 1/30th scale model was carried out in Wuhan University of Technology. The dynamic characteristics of structure are studied and its dynamic responses under different levels of earthquake are investigated. Using the shaking table test data and the observed cracking pattern, studies on seismic performance and failure mechanism of tested model are performed. The weakness parts of the structure are investigated and the suggestions and measures to improve the seismic ability of structure are presented.
