Shaking Table Model Test

Standing 250m above the ground level, the tower employs a complicated modern tall building system that involves the use of a reinforced core, two strengthened trusses and eight composite (concrete encased steel) mega-columns in the exterior perimeter of the building to resist vertical and lateral loads. A shaking table model test was carried out according to owner’s commission due to its complexity and the requirement of the Chinese Design Codes. In this paper, test equipments and test results were analyzed and some conclusions were given. The method applied in this model test will be helpful to other similar experimental studies.

Shaking Table Model Test

A building developed by Wuhan Shimao Group in Wuhan, China, is a high-rise residence with 56 stories near the Yangtze River. The building is a reinforced concrete structure, featuring with a nonregular T-type plane and a height 179.6 m, which is out of the restrictions specified by the China Technical Specification for Concrete Structures of Tall Building (JGJ3-2010). To investigate its seismic performance, a shaking table test with a 1/30 scale model is carried out in Structural Laboratory in Wuhan University of Technology. The dynamic characteristics and the responses of the model subject to different seismic intensities are investigated via the analyzing of shaking table test data and the observed cracking pattern of the scaled model. Finite element analysis of the shaking table model is also established, and the results are coincident well with the test. An autoregressive method is also presented to identify the damage of the structure after suffering from different waves, and the results coincide well with the test and numerical simulation. The shaking table model test, numerical analysis, and damage identification prove that this building is well designed and can be safely put into use. Suggestions and measures to improve the seismic performance of structures are also presented.
