AbstractThe Midea Shanghai Innovation Campus comprises two interlocking L-shaped towers supported by seven reinforced concrete core tubes. Long-span cable-stayed structures are longitudinally arranged between these tubes.A46-meter-span cantilever trussis positioned atthe tower end，while additional cantilever trusses extend laterally from thecentral longitudinal structure to both wings，forming the building's frame structure. Thisstructural design draws inspiration from cable-stayed bridge principles，integrating cable-truss combinations within the building.By applying prestress to the cables，structural deformation and internal forces are reduced.The system is novel and fals under the category of special over-limit high-rise structures not covered by existing national codes.A higher seismic performance objective was adopted，necessitating comprehensive analysis and validation to achieve targets.To verify the safety and constructability of cableframe connections，detailed finite element analysis and a full-scale joint test were conducted.Furthermore， construction process simulation analysis was performed to verify feasibility and determine prestressing force controls for each construction stage.
