Arup’s Tall Buildings in Asia

"Preface – About Arup Tall Building Overview of the book and Arup’s building design philosophy. By: Dr Goman Ho (Arup Fellow in Tall Buildings) Foreword Foreword 1 - By: Mr Michael Kwok, Arup East Asia Chairman Foreword 2 - By: Prof. You-Lin Xu, Dean of Faculty of Construction and Environment The Hong Kong Polytechnic University CASE STUDY Ambitiously Tall Tall buildings are viewed as a symbol of a city’s socio-economic power and the source of pride of its people; they are becoming increasingly tall and peculiar in shape. How can we realise height? Raffles City Chongqing, Chongqing, China Highlight: A patented hybrid outrigger system to achieve 9.4 slenderness ratio in two 350m tall buildings. Also a 280m long seismically isolated glass-clad conservatory floating 265m above the ground. Tianjin Goldin Finance 117 Tower, Tianjin, China Highlight: 597m tall building in high seismicity region, supported by four steel mega columns, perimeter cross-bracing and belt truss. The Masterpiece (K11), Hong Kong Highlight: Vertical pre-stressing with belt truss and outrigger to realize a reinforced concrete building with an aspect ratio of 12. Facilitating construction Tall buildings, especially those in iconic shape, often suffer from high construction cost. As designers and engineers, what are we doing to facilitate construction, reduce construction time and cost? CCTV Headquarter, Beijing, China Highlight: Joining two 75m long cantilever steelwork from two inclined towers at 162m above ground; wind, temperature, stress built in the two inclined towers all matter. Vincom Landmark 81, Ho Chi Minh City, Vietnam Highlight: Tallest building in Vietnam upon completion. Difficult ground conditions, large scale of the project, fast-paced programme all pose challenges to the pile design and construction. Tianjin Goldin Finance 117 Tower, Tianjin, China Highlight: Soft soil and deep stiff strata resulting a foundation system with 941 nos. hundred meter long 1m diameter fiction piles. Tianjin Chow Tai Fook Finance Center, Tianjin China Highlight: The curvatures along this 530m tall building yield to 20 thousands unique irregular façade panels; Arup rationalized them to a thousand. All in one, vertically integrated Today tall buildings are often cities within a city, embracing all major functions of a city – office, hotel, retail, residential etc. But how to make the best use of space and make them all function well together, vertically? Changsha International Finance Square, Changsha, China Highlight: Effective vertical transportation strategy to achieve high handling capacity with minimum space. Guangzhou International Finance Centre, Guangzhou, China Highlight: Mixed-use tower has different MEP requirements at different building zones. Optimization is crucial to ensure maximum rentable area. Safe and comfortable Many people are afraid of getting trapped in a tall building during a fire / earthquake / super-typhoon / terrorist attack etc. Are our tall buildings designed safe enough? China Zun (Z15), Beijing, China Highlight: Structural fire engineering explains the possible interaction between different structural members during fire, allowing us to go beyond the prescriptive design codes. Nicolas G Hayek Center, Tokyo, Japan Highlight: An innovative ""self-mass damper"" system which transfers the floor slabs to mass dampers to ensure no collapse in 1 in a 1000-year earthquake in Tokyo. By: Ryota Kidokoro (Associate) Shanghai World Financial Centre, Shanghai, China Highlight: The first Chinese lift-assisted evacuation strategy reducing the evacuation time by almost 40% in this 101-storey building. China Resources Headquarters, Shenzhen, China Highlight: Apart from ensuring the tall building is safe in typhoon and earthquake, we also adopted motion simulator to help client determine the comfort criteria. Green Building Tall buildings are a major source of carbon emissions in cities due to energy consumption in their heating, cooling and ventilation systems. They also have adverse effect on the microclimate. How can we minimise their environmental impact and unleash their potential environmental advantages? China Resource Building, Hong Kong Highlight: Strategies to make a 25-years old building save 27% of water and 8% energy consumption. Ping An International Finance Centre, Shenzhen, China Highlight: Specific challenges in making a 599m super tall building ""green"" and Arup’s solutions. Hysan Place, Hong Kong Highlight: A LEED-CS Platinum project not only benefits the building owner and users, but also the community. How? Design in the digital age Latest tools and methods in tall building design. M+, Hong Kong Highlight: Implementing BIM from very beginning of the design stage for better design coordination and quicker design calculation. China Zun (Z15), Beijing, China Highlight: Parametric design has enabled automatic design process and optimized structural solutions. Total Design Arup integrated design approach bringing synergy to the tall building. Canton Tower, Guangzhou, China Highlight: An integrated effort by Arup’s structural and building services engineers, specialists in fire, seismic and wind, and lighting designers has realized the most elegant TV tower in the world. Marina Bay Sands, Singapore Highlight: This mega-project took four years to design and construct; without the multi-disciplinary and global Arup team, this is impossible. Index"
