Project Location:Doha, Qatar
Client:China State Construction Engineering Corp. Ltd.
Partner:Atelier Jean Nouvel
Product Category:Public building and business office
Specialty Involved:Building, structure and interior
•According to the local conditions of Qatar, a diversified range of design standards (i.e., BS, ASTM and EN) need to be taken into account, and to be implemented based on the specific specialties involved. The building construction standard adopts QCS standard. Our professional and international project management and designers have made significant contributions to the success of the project.
•The creep effect of the overall structural concrete of high-rise buildings is studied, and targeted technical measures are carried out to avoid the emergence of a new “Leaning Tower of Pisa”;
•The internal installation of steel bench in the core zone of cross column nodes for reinforcement is originated and has passed experimental verification, thus effectively ensuring the bearing capacity of nodes and the safety and reliability of structures;
•Nonlinear calculation is conducted on the whole-process construction simulation of prestress tensioning in complex super high-rise projects, which reveals the effectiveness of prestress;
•A complete nonlinear calculation is conducted on the whole-process simulation of construction, fully taking into account structural dead weight, temperature difference shrinkage, prestress, etc.;
•The study proposes and adopts a new method for the design of resistance to progressive collapse, retains the initial state and introduces collapse load;
•The study proposes to employ the linear buckling stability analysis of the overall structure to determine the calculation length of compressed members, thus ensuring their safety.
Curtain wall design
•The high-rise office building in Doha adopts the cascaded 3D butterfly-pattern unit shading louver with complex form; the curtain wall system of the project adopts combined 3D comprehensive multi-angle shading adjustment, and, as a brand-new curtain wall system, it is both designed and constructed for the first time in the world.
•The curtain wall system consists of three layers from inside out, i.e., the aluminum alloy exposed frame glass unit as the inner layer, the metal slidewalk as the middle layer and the cascaded 3D butterfly-pattern unit shading louver as the outer layer.
•To alleviate the impact of strong sunshine in the Middle East, the shading louvers are designed with different organically-cascaded layers based on their orientations.
