Abstract: The Innovation Service Center is the landmark architecture of Wuhan Smart Eco-city, it contains five tower buildings with the shape of shell. The main structure adopts reinforced concrete frame-shear wall structure system. Circular inclined column was adopted in outer ring to satisfy the facade effect. The angle of the inclined column increased layer by layer from 0° to 15°, and locally reached 25°. A variety of finite element softwares were uesd to evaluate the mechanical performance of the structure by structure static calculation, elastic-plastic time history analysis of large earthquake, stress analysis of the floor. And appropriate strengthening measures were put forward to ensure the seismic performance of the structure. The design of single steel structures such as large-span single-layer reticulated shells, spiral steel stairs, etc. were summarized, which provides reference for the design of similar projects.
Keywords:inclined column； static calculation； large-span； single-layer reticulated shell; spiral steel stair
