Abstract:The height of the Tianshan World Gate A#, D# commercial office building is 138m, and the structure is frame-shear wall structure. The two towers are connected by a steel truss spanning 80m at the roof. The overall structure is a high-rise connected structure. The structural plan, performance target, wind tunnel test, construction simulation and structural analysis method were introduced in detail. The YJK and PMSAP finite element software were used to analyze the overall structure of the structure under small earthquakes, and the elastic time history analysis method was used for supplementary calculation. The performance targets of small earthquake, medium earthquake and large earthquake were respectively checked. The SAUSAGE software was used to analyze the elasto-plastic dynamic time history of the structure under rare earthquake. The overall structural index meets the requirements of the specification and can achieve the predetermined seismic performance target. The design is safe, reliable and economical. It can be designed for the same type of high-rise over-limit structure for reference.

Keywords:super-limited connected structure; steel truss; wind tunnel test; construction simulation
