<p>Two identical high-rise reinforced concrete (RC) frame-core-tube structures, located in Beijing China and San Francisco America, respectively, are designed using the Chinese and the American codes. Methods to determine load, seismic action, and material strength for seismic design in the Chinese and American codes are presents in this paper, and the major differences of design results are compared. Elastic response of the two structures are calculated by the mode-superposition response spectrum method, and the member dimension, dynamic characteristics, displacement, and reinforcement are compared. Furthermore, the dynamic elastic-plastic behavior is conducted using 10 sets of earthquake waves to analyze the collapse probability. Results reveal that the two structures designed by the Chinese and American codes show some differences in the dynamic behavior, displacement and reinforcement in the boundary restraint elements of shear walls due to the different design methods in the Chinese and American codes.</p>

Tube Structure

With the development of economy and society, urban construction rose to a new level in China. High-rise and super high-rise building increase rapidly. In the high-rise and super high-rise buildings (H≥150 m), the structural system usually adopts the conventional reinforced concrete, including frame tube structure, tube in tube structure, steel frame with reinforced concrete core tube hybrid structure and tube in tube steel - concrete mixed structure. These traditional structural systems often lead to the problems of fat beam fat column and high expenditure, which is not economic and unfriendly to the environment. This paper not only presents a new type of concrete core wall and prefabricated space steel grid cassette tube in tube structure system, but also discusses the superiority of the new type structure through the innovation and practice of a super high (266 m) five-star hotel and office building integrated engineering construction.

Diagrid tube structure system has advantages on constructing high-rise buildings due to its great stiffness, however, its seismic performance analysis are limited. 10 CFST diagrid tube-concrete core tube structures are analyzed by Mode-Pushover method using Perform-3D program. The plasticity developing process and components yield order are summarized. The force distribution between diagrid and core tubes is researched and the force redistribution reason is explained from the change of diagrid tube forces. The structure lateral stiffness degradation is discussed based on the developing process of diagrid and core tubes lateral stiffness. The influences of main lateral stiffness related factors on the structure plasticity developing process, force distribution and stiffness change of the tubes are discussed at last.
