Abstract:Innovation Center of Science and Technology of Southern Sub-center of Chengdu is a large building group, the main building comprises several complicated structures with U-shaped plane and stepped faade.  Seismic analysis of complicated structure, design of overlength and large-span prestressed concrete structure, constructional measure of steel truss roof of atrium and awning, cohesive strength value of anchor bar in multiple soil layers and in rock layers, were introduced. Design conception for rational determination of tensile control force of prestressed reinforced bar was proposed, which can provide reference for similar structures.
Keywords:U-shaped plane and stepped faade; seismic analysis; prestressed structure; steel truss roof; anti-float anchor bar
