Abstract:The overground part of Aerospace City Primary and Secondary School project includes four single buildings of the primary school building, secondary school building, complex building and dormitory building; underground part is integrated as a whole, mainly including large-space ice hockey hall, gymnasium, lecture hall, swimming pool, equipment building and underground garage. In the underground part of the project, ice hockey hall and large-space gymnasium with large space adopt steel truss type; swimming pool adopts section steel reinforced concrete beam type; lecture hall adopts the 27m-span steel reinforced concrete transfer structure. The main body structure of the overground part adopts reinforced concrete frame-shear wall structural system. The key and difficult problems in the design of the project were mainly elaborated, including the design of steel truss and joint connection design under heavy loads, the design of 27m-span section steel reinforced concrete transfer beam, structural design of the retaining wall structure with complex force transfer caused by large space underground and sunken courtyard opening, ramp structural design of the lower 2 stories suspended below large-cantilever section steel beam on roof of primary school, and elastic-plastic analysis of complex building.
Keywords:truss joint connection; steel reinforced concrete transfer beam; steel truss; suspension structure; elastic-plastic analysis
