BRACED FRAME
• IT IS A DEVICE USED AS A SUPPORTING BEAM IN A BUILDING THAT
AND STEADIES THE STRUCTURE.
• IT IS EXTREMELY STIFF.
• IT HELPS POSITIONING, SUPPORTING, STRENGTHENING OR RESTRAINING
OF A STRUCTURAL FRAME.
• THE BASIC PRINCIPLES ARE AS FOLLOWS:
• A. EACH STORY MAY BE FULLY BRACED
• B.THE BRACING MAY RUN ACROSS SEVERAL STORIES
• C.VERTICAL K-BRACING MAYBE USED ALONG THE COLUMNS
• D. HORIZONTAL PORTAL BRACING MAY BE APPLIED ALONG THE BEAMS .
.
TYPES :
1. X- BRACING. 2. K-BRACING 3. XX-BRACING 4. KNEE BRACING
MATERIALS:
• ARE ALWAYS COMPOSED OF STEEL MEMBERS
CENTURY TOWER , JAPAN
• ARCHITECT : NORMAN FOSTER
• HEIGHT : 109.73M
• FLOOR : 29 (ABOVE GROUND)
• STRUCTURAL SYSTEM: BRACED FRAME STRUCTURE
• STRUCTURE TYPE: KNEE BRACING
• THE GIRDERS PARTICIPATE ONLY MINIMALLY IN THE LATERAL LOADS, AND
THUS, THE FLOOR FRAMING REMAINS INDEPENDENT OF HEIGHT. KNEE
BRACING
• THE BUILDING IS FOUNDED ON ROLLERS THAT ARE DESIGNED TO WITHSTAND
AN EARTHQUAKE CORRECTLY TO THE STEEL STRUCTURE IS INDEPENDENT OF
USING THIS STYLE OF STRUCTURAL EXPRESSIONISM BECAUSE AT ALL TIMES
THE STRUCTURE IS VISIBLE.
• THE EXTERIOR IS SOLVED WITH A CURTAIN WALL, WHILE THE PREDOMINANT
MATERIAL INSIDE THE GLASS WALLS AND SOME CEILINGS, STEEL
STRUCTURE, THE BLACK GRANITE IS USED IN PLACES WHERE IT OCCURS THE
WATER AND WOOD IS PRESENT IN SOME DOORS AND DIVISIONS

• THE BUNDLEDTUBE SYSTEM INVOLVES, INSTEAD OF ONETUBE, SEVERAL INDIVIDUAL
TUBES INTERCONNECTED TO FORM A MULTI-CELLTUBE.
• TOGETHERTHEYWORKTO RESISTTHE LATERAL LOADS AND OVERTURNING MOMENTS.
• WHENTHETUBES FALLWITHINTHE BUILDING ENVELOPE, INTERIOR COLUMNS ARE
POSITIONED ALONGTHEIR PERIMETERS.
• NOT ONLY ISTHIS SYSTEM ECONOMICALLY EFFICIENT BUT IT ALSO ALLOWS FOR MORE
VERSATILE BUILDING DESIGNS, ADOPTING INTERESTING SHAPES AND BUNDLED IN
DYNAMIC GROUPINGS RATHERTHAN BEING SIMPLY BOX-LIKETOWERS.
• THE FIRSTTYPE OF BUILDINGTO USETHIS SYSTEM WASTHEWILLISTOWER IN CHICAGO
BUNDLEDTUBE
• IT ISTHETALLEST BUILDING INTHEWORLD WITH ALL-STEEL STRUCTURE, COLUMNS]] AND BEAMS IN A SYSTEM “OF MEGAMÓDULO”.
• THETOWER STRUCTURE IS SOLVED WITH NINE SQUARE MODULES, EACH RIGIDWITHIN ITSELF WITHOUT INTERNAL SUPPORTS.
• THE FLOORS ARE SUSPENDED FROMTHETUBES, ATECHNOLOGICAL INNOVATION OFTHE ENGINEER FAZLUR KAHN, BASED ONTHE
THEORYTHAT A BUILDING BUILT ON A SERIES OFTUBES WOULD BE LIGHTER AND STRONGERTHAN A BUILDING BUILTTO ATRADITIONAL
STEEL SKELETON.
• ATTHE BASE OFTHE BUILDING 9 MODULES FORM A SQUARE, OF 22.86×22.86M, GROUPED AS A CLOSED SQUARE AND ARRIVE INTACT
THROUGHTHE FIRST 50 FLOORS, FINISHING AT DIFFERENT HEIGHTS AND CREATING A FORM WITH MULTIPLE LEVELS. FROMTHIS LEVEL
THE NUMBER OF MODULES /TUBES IS DECREASING UNTIL IT BECAME ONLYTWO STEELTUBES FROMTHE 90TH FLOORTOTHETOP.
• THE STRUCTURAL MODULES ARE INSERTED INTO REINFORCED CONCRETE CAISSONS REACHING BEDROCK AND ARE ALSO JOINED BY A
CONCRETE MAT.
• THE STRUCTURAL STEEL FRAMEWAS PRE-ASSEMBLED IN SECTIONS ANDTHEN BOLTED IN PLACE. EACH MODULE 7.6×4.6MWAS
PREFABRICATED ANDTHENTO BETAKENTO PLACE LARGETRUCKS AND ONCE PLACED IN PLACE BY CRANES, JOIN CONNECTIONS.
• SKIN, LIGHTWEIGHT, BLACK ALUMINUM AND BRONZETINTED GLASS REDUCES REFLECTIONS AND SERVES AS INSULATION BETWEEN
THE INNER AND OUTER STRUCTURE IN ORDERTO MAINTAIN A RELATIVELY CONSTANTTEMPERATURE, WHICH MINIMIZES THE
EXPANSION AND CONTRACTION OFTHE FRAME.
