摘要：
The frame-core-tube structural system is one of the common structural systems used in supertall buildings. While a shear adjustment regulation for the frame of a frame-core tube structure has been specified in related Chinese codes, its applicability in supertall buildings needs to be further studied. Similar regulations in the codes of China and the United States are compared in this work. Furthermore, based on an actual supertall building, a new design is proposed by changing the shear adjustment strategy. Then the refined finite element (FE) models of both original design and new one are established. And both nonlinear time history analysis (THA) under the maximum considered earthquake (MCE) and earthquake-induced collapse analysis are performed for these two models. The results indicate that: compared with the original design, the new one, whose shear adjustment strategy is different, has a lower design difficulty, a similar aseismic performance under MCE, and a higher anti-collapse resistance. The results can provide a reference for the design of supertall frame-core tube structures. © 2019, Engineering Mechanics Press. All right reserved.
