Investigations into the specific organization of subsystems and their function will demonstrate the architect/ engineer’s methods of reasoning and decision making, and will also expose unexplored design possibilities that could have been used for better building system integration. The investigation will give factual descriptions of the building parts; express the plausible design reasoning behind the building’s systems, both teleological and functional; and propose alternative design possibilities. We would like to acknowledge Skidmore, Owings, & Merril for graciously allowing us the opportunity to study the construction documents for the Jin Mao Tower. We would also like to thank our professor, Dr. Michael Kim, for enlightening us with the knowledge of synergistic building design. This study will be based on information from construction documents, site visits, and consultations with the architects and engineers of the building. 金茂大厦 jin mao tower TABLE OF CONTENTS: CHAPTER 1: INTRODUCTION.......................................................................................................4 CHAPTER 2: BUILDING CONFIGURATION AND SPACIAL ORGANIZATION...............................7 CHAPTER 3: SUPERSTRUCTURES...................................................................................................18 CHAPTER 4: SUBSTRUCTURES.......................................................................................................28 CHAPTER 5: CURTAIN WALL DESIGN...........................................................................................36 CHAPTER 6: MECHANICAL SYSTEM OVERVIEW.........................................................................43 CHAPTER 7: SPACE CONDITONING SYSTEMS............................................................................49 CHAPTER 8: ELECTRICAL SYSTEMS..............................................................................................55 CHAPTER 9: SOURCES.................................................................................................................60 3 金茂大厦 4 jin mao tower CHAPTER 1: INTRODUCTION SITE ORIENTATION 金茂大厦 jin mao tower The most recognized building in China, inspired by the traditional tiered pagoda, is the Jin Mao Tower by Skidmore, Owings, and Merril. A skyscraper at eighty-eight stories tall, the tower rises out of the Lujazui area of the Pudong district of Shanghai in the People’s Republic of China at a total of 420.5 meters (fig.1.0, 1.6). Built on 290,000m2 site in a major finance and trade center for China, the building is estimated to have cost $530 million dollars US. The building is located on a 24,000 square meter plot of land near the Lujiazui metro station. Owned by the Jin Mao Group Co, LTD (formerly China Shanghai Foreign Trade Centre Co. Ltd), the building is a multipurpose structure with offices on the first 50 levels of the building and the Shanghai Grand Hyatt Hotel on the following 38 levels. Just east of the Huang Pu River, the Jin Mao Tower shares the skyline of Pudong with the Oriental Pearl Tower, the Shanghai World Financial Center and the Shanghai Tower. Providing not only office space for financial and trade organizations, the Jin Mao Tower also has a shopping mall, food court, concert hall, and parking for cars and bicycles (fig.1.2,1.3). 5 1.0 1.2 1.3 金茂大厦 1.4 1.5 6 jin mao tower Taking up an entire block, the Jin Mao complex consists of a podium which houses J-Life, the retail center for the complex, on the west side of the building site. The tower, which houses office space, several restaurants, a club, a hotel, and an observation deck, is located on the east side of the building site (fig. 1.4,1.5). Head architect Adrian D, Smith from Sikdmore, Owings, and Merril, and head engineer Stanton Korista, also for Skidmore, Owings, and Merril, lead the design process from 1993 until completion in 1998. Over 30 architects and engineers worked on the project. Opening on August 28, 1998 with respect to the lucky number eight, which was a major player in the concept and design process, the building construction process was on an accelerated schedule. 1.6 金茂大厦 7 jin mao tower CHAPTER 2: BUILDING CONFIGURATION & SPACE ORGANIZATION AND THE OVERALL SYSTEM OCCUPANCY CONFIGURATION RISER DIAGRAM 金茂大厦 jin mao tower Occupancy: The Jin Mao Tower is a multiuse space with 123,000m square of office space, a shopping mall, a food court, several restaurants, conference and banquet facilities, nightclubs, parking for 600 cars and 7500 bikes, and a hotel. The building is serviced by 61 elevators and 19 escalators. With such a complex group of occupants, the circulation and transportation of the occupants becomes essential. Managed by the eleavator riser system, occupants are directed through the building by a very selective program. 8 金茂大厦 jin mao tower 9 The following page (fig. 2.0) is a section diagram of the function of each level. There is a lobby, five different office zones, a double height mechanical level, and hotel. These all sit next to a six level podium building. The building’s major tenant is the five-star, 555-room Shanghai Grand Hyatt hotel which occupies floors 53 to 87. The Hyatt’s barrel-vaulted atrium starts at the 56th floor and extends upwards to the 87th. Lined with 28 annular corridors and staircases arrayed in a spiral, it is 27 m in diameter with a clear height of approximately 115 m. It is one of the tallest atriums in the world. The hotel floors also feature: 53/F: The Piano Bar, a jazz club. 54/F: The hotel lobby and Grand café, served by an express elevator from the tower's ground floor. 55/F: Canton, a high-end Cantonese restaurant that takes up the entire floor. 56/F: On Fifty-Six, a collection of restaurants including The Grill, the Italian Cucina, the Japanese Kobachi, and the Patio Lounge, which is located at the base of the atrium. 57/F: Club Oasis, a fitness club featuring the world's highest swimming pool. 85/F: Highest rooms; this is also a transfer level for the elevators going to the two floors above. 86/F: Club Jin Mao, a Shanghainese restaurant. 87/F: Cloud 9, with a split-level mezzanine called the Sky Lounge. It is chosen by some visitors as a comfortable alternative to the observation deck above, since the lowest-priced drinks are the same price as the admission to the deck.

CORE PLAN LATERAL FORCES base is extended STRUCTURAL DUALITY COMPRESSION/ LATERAL FORCES base is extended The Jin Mao was envisioned as a flexible and slender structure, thus, the building was constructed using both steel and concrete. As a composite building, materials could be located where they most efficiently resist loads, thus minimizing cost and materials. Reinforced concrete, with its mass, strength, stiffness, and damping characteristics, combined with the strength, speed of construction, long-span capabilities, and lightweight characteristics of structural steel were combined to control building behavior and maximize structural efficiency. 金茂大厦 21 jin mao tower CORE (SHEAR WALL) - The southeast coastal region of China is impacted by .

The composite approach also enabled the engineers to hollow out that portion of the central core where structural demands were less, and to create the tower’s centerpiece – a 650-foot-high atrium, tallest and highest in the world, extending up from the 56th floor.

Concrete and steel both deform elastically, but concrete also creeps and shrinks over time. For a building as tall as the Jin Mao, vertical displacement at the top could be as much as 12 inches. More significant is the relative movement between neighboring vertical elements, especially the core relative to the composite mega-columns that are interconnected with the stiff steel outrigger trusses. MEGACOLUMN PLAN 金茂大厦 When subjected to large relative displacements, these trusses would attract forces MEGACOLUMN so great that they could be ripped apart. To counteract these forces, the engineers introduced pins into the trusses to allow rotation during construction. They did not bolt the connections until after the structure was completely built. After the bolts were installed, the structure was capable of resisting all future design loads. In addition, pins would also fuse and dissipate energy during earthquakes; after an event, friction in the joints is restored by high-strength bolts. During moderate earthquakes the joint remains fixed, but during a severe earthquake, the joints rotate. This allows the building to be flexible, dissipating energy and reducing potential damage. After the earthquake, the Pin-Fuse Joints return to their original positions.

The main components of the foundation are the pile cap and the piles. Piles are long and slender members which transfer the load to deeper soil or rock of high bearing capacity avoiding shallow soil of low bearing capacity. The foundations rest on 1,062 high-capacity steel piles driven 83.5 m deep in the ground to compensate for poor upper-strata soil conditions. At the time those were the longest steel piles ever used in a landbased building. The piles are capped by a 4 m-thick concrete raft 19.6 m underground. The basement’s surrounding slurry wall is 1 m thick, 36 m high and 568 m long, and composed of 20,500 m³ of reinforced concrete. Pipe piles are a type of steel driven pile foundation and are a good candidate for battered piles. Pipe piles can be driven either open end or closed end. When driven open end, soil is allowed to enter the bottom of the pipe or tube. If an empty pipe is required, a jet of water or an auger can be used to remove the soil inside following driving. Closed end pipe piles are constructed by covering the bottom of the pile with a steel plate or cast steel shoe. The amount of corrosion for a steel pipe pile can be categorized; for a pile embedded in a non aggressive and natural soil, 0.015 mm per side per year can be assumed from the British Steel Piling Handbook. Eurocode 3 now specifies various corrosion rates based on the nature or soil conditions and pipe pile exposure. Steel pipe piles can either be new steel manufactured specifically for the piling industry or reclaimed steel tubular casing previously used for other purposes such as oil and gas exploration. 金茂大厦 金茂大厦 34 jin mao tower jin mao tower REINFORCED CONCRETE COLUMN STEEL PILES STEEL PIPE PILE - The foundations rest on 1,062 high-capacity steel piles driven 83.5 m deep in the ground to compensate for poor upper-strata soil conditions.

Water: The system in the Jin Mao tower is designed to be airtight and waterproof. Weeps are provided at each line of flashing to insure positive drainage. Exterior walls that enclose heated spaces are designed to meet the criteria for condensation control. Vapor barriers are placed on the warm side of the exterior wall. Positive drain holes are provided inside the aluminum window wall mullions and panels. All weep holes have a baffle. Thermal Change: The design temperature for the tower is 21 degrees Celsius. Thermal expansion/contraction and movement joints fulfill the exterior wall performance requirements resulting from a temperature change between -10 degrees to 40 degrees Celsius. Sponge Neoprene Glazing Gaskets and Silicone Glazing Gaskets allow for thermal expansion of the glazing. Construction Tolerance: The typical floor deflection is 20mm, while differential settlement is designed to be 8mm per 4 stories. In order to compensate for anticipated axial shortening of the structure as it is being erected the erection of the exterior wall commenced prior to the completion of the tower structure and prior to the application of superimposed dead loads on a particular floor. Copings, parapets, fins, and decorative elements were designed to withstand a 90kg concentrated load applied in any direction. Ease of Installation: All panels are prefabricated and assembled as a unit system. Aesthetic Value: An elegant skyscraper, the exterior enclosure system is covered with aluminum tubing lattice work and fins to provide a light pollution filter. 金茂大厦 38 jin mao tower CURTAIN WALL PANELS 金茂大厦 jin mao tower Thermal expansion/contraction and movement joints fulfill the exterior wall performance requirements resulting from a temperature change between -10 degrees to 40 degrees Celsius.
