| Abstract: | The main roof height of Shanghai Magnolia Plaza is 300m,and the full height of the building is 320m.Frame-core-outriggers structural system was adopted in the structure.The frame was composed of steel reinforced concrete composite columns and steel beams,the core was made of reinforced concrete shear walls,and the peripheral frame and inner core were connected with outriggers and belt trusses.The foundation includes 1m diameter,61m long cast-in-site piles with post grouting technology and mat of 4.3m thickness in this project.Structural performance index,structural calculating result,vertical deformation difference analysis and disposal measures,outriggers and belt trusses design,and elasto-plastic analysis were introduced. |
