Abstract:There are 17-4m-span large cantilever structure set at the level of 16-45m on both the west and east side of the Qianhai Justice Mansion. The second and third layers of the building are through the high space inside the building to create an open hall with the large space structure spanning 35-8m span. The structure adopts steel frame-corewall structure with oblique tensile rods. In the design, strategies were adopted including the self-balancing control of the structure, strengthening the rigidity of the corewall, controlling the horizontal displacement of the structure and the stress of the tensile rod. The gravity load of the upper 8 layers of frame structure was transferred to the ground corewall and frame columns by the oblique tensile rods. The structural system selection and structural design strategy were introduced emphatically as well as force transmission path under the influence of gravity, serviceability analysis, reasonably determination and simulation of the construction sequence, rod tensile stress control, joint design and working performance of the structure under various loads.
Keywords:oblique tensile rod; stress control of tensile rod; construction sequence; construction simulation; serviceability; joint design
