⑥ By ingeniously setting tie concealed beams in the floor where the diagonal braces intersect with the floor, the calculated length of the support is reduced, so that the support is made thinner and the scheme effect is maximized.
Under the 8 degree earthquake, except for a few energy dissipation braces as the first seismic defense line, the main frame is in good performance.
In this scheme, lattice columns are designed to support each other and achieve the effect of self balance by using the characteristics of co inclined and symmetrical lattice columns.
Ubisoft Science and Technology Headquarters Building is a typical representative of innovative design, which sets a new standard for the future workplace and will become a new landmark of Shenzhen Science and Technology after the completion of the project.
⑤ The component mainly bears the axial force, so the material utilization rate is high.
The structural calculation and analysis conducted a comprehensive analysis of the structural system and seismic performance: overall stability, component stability, comfort of long-span and long-span cantilevered structures, bearing capacity of concrete filled steel tubular columns, special analysis of mega frame related floors, overall anti overturning analysis, and structural anti small, medium and large performance analysis.
Introduction of Structural Design – Architectural Scheme Features The Science and Technology Headquarters Building Project has a novel shape.
Before the installation of the beam, the self weight will dump inward and cause deformation.
System innovation ① No core tube is set inside the tower, and the main lateral resistance structure is the steel frame of the outer ring composed of building keels – supporting tube.
Ubisoft Technology Headquarters Building is located in Liuxiandong Headquarters Base, Xili, Nanshan District, Shenzhen.

It is far beyond the performance requirements of Shenzhen (7 degrees) fortification on the structure, further verifying the safety of the main body.
The scheme of adding facade truss and filling temporary support beam at the full height position is adopted.
In traditional practice, concrete core tube can be set in the concentrated area, and the large space at the bottom can be realized through truss conversion, which becomes a frame diagonal tube structure with conversion.
In order to achieve the new shape and functional space requirements designed by the architect, the structural innovation adopts the upper steel frame central support tube structure system, and the bottom adopts the giant steel frame structure; Periphery frame columns and giant diagonal braces are transformed through lattice mega frame, and only four corner special-shaped lattice columns are left on the ground.
The real picture shows that some of the built heights have restored the architectural effect.
Wind rope (stay cable)+jig frame scheme: it is difficult to solve the problems of cable length adjustment, high cost and affecting the construction period during layer by layer construction.
④ The external support tube has large lateral force arm, higher efficiency, high stiffness, and excellent wind resistance and seismic resistance.
If the architectural scheme is realized according to the structural system, it will inevitably lead to large beam column equal section, heavy structure, and can not restore the architectural effect well; The indoor large-span beam is high, which affects the use quality of the middle large-span office area.
⑨ The “small lower” facade has a novel shape, providing a larger space for the bottom lobby.
⑦ The special-shaped lattice column is innovatively adopted at the bottom, which is small at the bottom and large at the top.
⑩ The mega frame has large rigidity and high bearing capacity, avoiding the formation of weak layers at the bottom.
Construction status At present, the project is under construction, and the main body has been constructed to the 22nd floor.
The structural design is combined with the architectural characteristics.
Finally, only one frame column needs to be converted by the truss in each elevation.
Achieve harmony and unity between architecture and structure.
It has a very positive impact on cost and construction period.
The design innovation construction scheme is that the bottom of the giant lattice column is small and large.
According to the architect’s design ideas, the bottom of the building only has “four legs” on the ground, and the upper facade is an oblique grid curtain wall skeleton.
In the future, it will become a new core leading the development of high-tech industries in Nanshan and even Shenzhen.
③ The external facade support tube replaces the core tube, and there are only four columns inside the building, which can realize flexible layout of large space.
② The large span area at the bottom is designed as a mega frame, and combined with the architectural modeling, it is designed as a special-shaped lattice column and a mega truss beam.
In this project, the building keel is designed as the anti lateral force component of the main structure.
Support column+jig frame scheme: high cost, impact on construction period and low safety.
Liuxiandong Headquarters Base is one of the six headquarters bases that drive the economic development of Shenzhen, and one of the nine clusters of strategic emerging industries in Shenzhen.
At the same time, the number of statically indeterminate is high, and the continuous collapse resistance is good.
The architectural modeling is realized by outsourcing the curtain wall.
The calculation results show that the structure has a strong ability to resist continuous collapse, and has excellent wind resistance and seismic performance.
Project location: Nanshan District, Shenzhen Project type: super high-rise office building Building area: 93000 square meters Building height: 199.25 meters Owner: Shenzhen Youbishan Technology Industry Co., Ltd.
In the building plan, the upper left corner and lower right corner are vertical traffic concentrated areas.
⑧ The “large upper part” reduces the span of the conversion truss, and the number of columns converted by the truss also decreases.
The steel structure with light deadweight, high strength and good ductility is adopted.
