The height o f T1 and T2 tower
building is 249.5 m and 239.0m, respectively. The frame-core tube structure system is adopted, and the upper part is partially retracted
into a frame-shear wall structure. The structure has over-limit content such as super-high height, facade retracting, irregular torsion,
conjoined parts, discontinuous components, sudden changes in bearing capacity and inclined wall conversion. The YJK and ETABS
software are used to perform feasibility analysis, floor stress analysis, cantilever and conjoined structure analysis, comfort analysis and
cross-storey column buckling analysis on the structure under frequent earthquakes and fortified earthquakes. Using SAUSAGE software
to analyze the structural dynamic elastoplastic analysis, elastoplastic floor stress analysis, using ABAQUS software to transform the
structure, steel beam opening, complex joint analysis and other structural special research. Through the analysis and comparison o f the
calculation results, it is proved that the structural design has successfully solved the problem o f structural over-limit, and the structural
design is safe and reliable, which can provide reference for related projects.[Keywords ] super-high rise ; seismic design ; analysis o f dynamic elastic-plastic response ; time history analysis p W^ ?6? ??rRM ?n ?
