The TCL Advanced Semiconductor Display Industry Headquarters project adopts the concrete-filled steel tubular column+bottom arch structure frame(steel beam)+reinforced concrete core tube structure system.The bottom arch structure is composed of upper arch,lower arch and tension beam.The upper arch of the four sides is converted into 15 outer frame columns.The lower arch only bears the load of 2～4 floors.The tension beam located on the basement roof balances the horizontal thrust of the arch structure,and the core tube is arranged in double tubes.By comparing the stress characteristics of arch truss and single arch conversion structure form,and considering the factors such as building effect,structural cost and construction feasibility,the basis of adopting single arch conversion structure form in this project was discussed.Combined with the structural characteristics of the project,the corresponding performance-based design objectives were formulated,and the performance test calculation of small,medium and large earthquakes were carried out.The comfort of large-span floors was checked,and the main steel structure joints were given.The analysis results show that the structural design of this project is reasonable,and the overall performance meets the set performance goals.
