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.

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.

Important Basis

The failure shaking table model test of mass concrete structures is an important basis for understanding to the actual failure of structures. This paper derived all kinds of similar scales between model and prototype in nonlinear dynamic shaking table test, and constructed the reduced scale nonlinear numerical simulation model. The numerical results show that the failure of model and prototype matches the nonlinear similarity theory. Besides, the effect of the characteristics of ground motion was studied and it cannot be ignored to ensure the accuracy of the test.

High Rise

Reinforced concrete eccentric frame-shear wall structure has been widely used in engineering. However, this structure is mainly used for high-rise structure, and it is difficult to obtain accurate earthquake response of structure through experimental study. Therefore, simulation software needs to be used for study on seismic performance of high-rise structures. This paper produces useful conclusions for the project through shaking table test and the simulation of seismic performance provided by ANSYS finite element analysis software.

Shaking Table Model Test

A shaking table model test is conducted for Guangzhou West Tower to study its seismic behavior in State Key Laboratory for Disaster Reduction in Civil Engineering at Tongji University. Guangzhou West Tower adopts a new structure system and the significant characteristic of this system is the non-perpendicular frame arranged around the building, acting both as columns and bracings. Based on the similarity theory and member equivalent principle，a 1/80 scale model of this building is made of polymethyl methacrylate(PMMA). The model’s dynamic characteristics, earthquake-resistant behavior, responses of acceleration and deformation under different wave peak values are investigated, then the seismic responses of the prototype structure are deduced and analyzed. The whiplash effect of the prototype structure is studied, and the weak position of the structure is found out. The experiment results demonstrate that it is feasible to apply this structural type to practical engineering. Finally, some suggestions for the engineering design of the prototype structure are put forward.
