Continuing my modern wonders series, I present Taipei 101, the second largest building in the world However, it contains the largest tuned mass damper ever constructed. As well the building is the first record-setting skyscraper to be constructed in the 21st century. Includes Building Large & Small PCXs, as well as City Screen buildings Large & Small PCXs and Wonder Splash. Spoiler : #BLDG_Taipei ^ ^[Taipei 101] makes two unhappy citizens $LINK<content=GCON_Moods> in its city. It also reduces $LINK<War Weariness=GCON_War_Weariness> for its city, and increases tax revenue allocated to the $LINK<treasury=GCON_Commerce> by 50%. #DESC_BLDG_Taipei ^ ^Taipei 101 is a landmark skyscraper located in Taipei, Taiwan. The building was the world's tallest (with occupiable floors) until it was surpassed in height by the Burj Khalifa, which was still under construction, on July 21, 2007. The tower has served as an icon of modern Taiwan ever since its opening. Taipei 101 comprises 101 floors above ground and 5 floors underground. The name of the tower reflects its floor count and carries symbolic meanings alluding to technology and Asian tradition. Its postmodernist approach to style incorporates traditional design elements and gives them modern treatments. ^ ^Skyscrapers must be flexible in strong winds yet remain rigid enough to prevent large sideways movement (lateral drift). Flexibility prevents structural damage while resistance ensures comfort for the occupants and protection of glass, curtain walls and other features. Most designs achieve the necessary strength by enlarging critical structural elements such as bracing. The extraordinary height of Taipei 101 combined with the demands of its environment called for additional innovations. The design achieves both strength and flexibility for the tower through the use of high-performance steel construction. Thirty-six columns support Taipei 101, including eight "mega-columns" packed with 10,000-psi concrete. Every eight floors, outrigger trusses connect the columns in the building's core to those on the exterior. These features combine with the solidity of its foundation to make Taipei 101 one of the most stable buildings ever constructed. The foundation is reinforced by 380 piles driven 80 m into the ground, extending as far as 30 m into the bedrock. The stability of the design became evident during construction when, on March 31, 2002, a 6.8-magnitude earthquake rocked Taipei. The tremor was strong enough to topple two construction cranes from the 56th floor, then the highest. Five people died in the accident, but an inspection showed no structural damage to the building, and construction soon resumed. A 660 metric tons steel pendulum that serves as a tuned mass damper. Suspended from the 92nd to the 88th floor, the pendulum sways to offset movements in the building caused by strong gusts. Another two tuned mass dampers, each weighing 6 metric tons sit at the tip of the spire. Taipei 101's characteristic blue-green glass curtain walls are double paned and glazed, offer heat and UV protection sufficient to block external heat by 50 percent, and can sustain impacts of 7 metric tons (8 short tons). Recycled water meets 20-30 percent of the building's water needs. ^ ^A multi-level shopping mall adjoining the tower houses hundreds of fashionable stores, restaurants and clubs. As well, a large park at the base of the tower acts as a giant sundial, using the tower's shadow as its pointer. Download.
