  2. 2. What is a high-rise building? “A building whose height creates different conditions in the design, construction, and use than those that exist in common buildings of a certain region and period.”
  3. 3. • Scarcity of land in urban areas • Increasing demand for business and residential space • Economic growth • Technological advancements • Innovations in Structural Systems • Desire for aesthetics in urban settings • Concept of city skyline • Cultural significance and prestige • Human aspiration to build higher Demand for High-Rise Buildings •Buildings between 75 feet and 491 feet (23 m to 150 m) high are considered high-rises. Buildings taller than 492 feet (150 m) are classified as skyscrapers. •The materials used for the structural system of high-rise buildings are reinforced concrete and steel. Most American style skyscrapers have a steel frame, while residential tower blocks are usually constructed out of concrete.
  4. 4. • The great pyramid of Giza, 2560 bc, was 146 meters tall and its height was unsurpassed until at least the 14th century ad. • The two towers of bologna in the 12th century reached 97.2 metres in height. • The 16th-century city of shibam consisted entirely of over 500 high-rise tower houses. MEDIEVAL PERIOD • HISTORY EARLY PERIOD •An early development was oriel chambers in liverpool. •Designed by local architect peter ellis in 1864, • The building was the world's first iron-framed, glass curtain-walled office building.

  6. 6. STRUCTURAL AND CONSTRUCTION ASPECTS the floor slab & its supporting beams are on the 10th or 100th storey. Since each floor carries more or less the same load. This is not the case with the core’s columns, which carry the weights of all the floors above. The lower-floor columns carry much larger than those at the top. The topmost columns carry only the load of the roof & their own weight. What is Structure Efficiency - Materials - Gravity System - Lateral System -Foundation Constructability - Simplicity - Time

  9. 9. Structural Systems Analyses of structural loads are generally given precedence in calculations/design measurements For high-rises. A structural equivalent load is often used to analyze the dynamic influence and yet dynamic are often especially important both for construction and operation.
  11. 11. Types of floor systems •In concrete floor systems, slabs of uniform thickness are often used with spans of 3m to 8m. •Beam and slab system is used with beams spaced at 3m to 8m. Beam depths of L/15 to L/20 are used. Concrete floor system Concrete floor Steel Floor Systems •In steel floor systems, we use reinforced concrete slabs on steel beams. Thickness of slabs is in the range of L/30 to L/15 of the span. •The stub lengths are 1.5m to 2m long. Stub girders are of composite construction. •Concrete • Prestressed concrete • Steel • Composite
  12. 12. Prestressed concrete is a method for overcoming concrete’s natural weakness in tension. It can be used to produce beams , floors or bridges Prestressed concrete Composite

  14. 14. Shear Frame System • Resists lateral deformation by joint rotation • Requires high bending stiffness of columns and beams • Rigid joints are essential for stability • Not effective for heights over 30 stories Braced Frame System • Lateral forces are resisted by axial actions of bracing and columns • Steel bracing members or filled-in bays • More efficient than a rigid frame Frame-shear truss interaction Braced Frame System
  15. 15. Wall-Frame Structure •The walls and frame interact horizontally, especially at the top, to produce stiffer and stronger structure. The interacting wall-frame combination is appropriate for the building in the 40 –60 story range, well beyond that of rigid frames or shear walls alone. •The braced frames behave with an overall flexural tendency to interact with the shear mode of the rigid frames. Rigid Frame Structure •Consist of columns and girders joined by moment resistant connections. Lateral stiffness of a rigid frame bent depends on the bending stiffness of the columns, girders, and connection in the plane of the bents. •It suited for reinforced concrete buildings and steel frame
  16. 16. Flat-Plate and Flat Slab Structure •it consists of uniforms slabs, connected rigidly to supporting columns. •Economic for spans up to about 25 ft (8m),above which drop panels can be added to create a flat-slab structure for span of up to 38 ft (12m). •Suitable for building up to 25 stories height. In-filled Frame Structure make it difficult to predict with accuracy the stiffness and strength of an in-filled frame. In-filled Frame Structure In-filled
  17. 17. Shear Wall Structure •Technology exists to pump and to place high-strength concrete at high elevation. •Fire rating for service and passenger elevator shafts is achieved by simply placing concrete of a determined thickness. •Shear wall formed around elevator and service riser requires a concentration of opening at ground level where stresses are critical. •Shear wall vertical movements will continue throughout the life of the building. Coupled Wall Structure •Consist of two or more shear walls in the same plane, or almost the same plane, connected at the floor levels by beam or stiff slabs. •Suited for residential construction where lateral-load resistant cross walls, which separate the apartments, consist of in- plane coupled pairs, or trios, of shear walls between which there are corridor or window openings. Shear wall structure Shear wall Coupled wall Coupled Wall Structure
  18. 18. The Trussed tube •Interconnect all exterior columns to form a rigid box, which can resist lateral shears by axial • Making the diagonal intersect at the same point at the corner column. •This creates the x form between corner columns on each façade. •Relatively broad column spacing can resulted large clear spaces for windows, a particular characteristic of steel buildings. Example of trussed tube Tube-in-Tube or Hull Core Structure •consists of an outer frame tube, the “Hull,” together with an internal elevator and service core. •The Hull and core act jointly in resisting both gravity and lateral loading. •The outer framed tube and the inner core interact horizontally as the shear and flexural components of a wall-frame structure, with the benefit of increased lateral stiffness.
  19. 19. Bundled-Tube structures •The concept allows for wider column spacing in the tubular walls than would be possible with only the exterior frame tube form. •It modulate the cells vertically can create a powerful vocabulary for a variety of dynamic shapes Core and Outrigger Systems •The outrigger systems may be formed in any combination of steel, concrete, or composite construction. •the complete elimination of uplift and net tension forces throughout the column and the foundation systems. •Exterior framing can consist of “simple” beam and column framing without the need for rigid-frame-type connections, resulting in economies. •Locating outrigger in mechanical and the natural sloping lines of the building profile
  20. 20. Vertical Loads LOADS ON THE HIGHRISE STRUCTURES •Dead loads arise from the weigh to the individual construction elements and the finishing loads. •Live loads are dependent on use depending on the number of stories; live loads can be reduced for load transfer and the dimensioning of vertical load-bearing elements. · However, the reduction of the total live load on a construction element may not exceed 40%. Horizontal loads •Calculation of lateral loads should be carefully scrutinized. •It generally arises from unexpected deflections, wind and earthquake loads Vertical load Horizontal load Ground surface Steel beam Foundation Steel column
  21. 21. Structural Loads • Gravity loads – Dead loads – Live loads – Snow loads • Lateral loads – Wind loads – Seismic loads • Special load cases – Impact loads – Blast loads Earthquake Load Blast Load Wind Load Impact Load Snow Load Dead Loads Live Loads Wind load

  57. 57. Design Features Our design sets out to demonstrate an ecological approach to tower design. Besides meeting the Client’s program requirements for an exposition tower (i.e. for retail, exhibition spaces, auditorium uses,etc.), the design has the following ecological responses Loose- fit design (e.g Sky courts, removable partition, Removable floor, mechanical-jointing, flexible design).(Increase space function reusability over the-150 years Life span) .
  58. 58. Level-2: Service core, food court. Level-3: Service core, Art & craft stalls. Level-4: Same of ass level 3 Dr. Yeang is among the leaders who seek to prove not only that wind, rain, sun and nature can and should be in harmony with human development, but that the ecologically balanced urban environment is itself a living organism
  59. 59. Level-5: Service core, food court. Level-6: Service core, Cafe. Level-9: Service core, Auditorium, Seating area. Level-10: Service core, sky park, seating, upper link. The architects have completed a study of the embodied energy and greenhouse-gas efficiency of the building materials as well, but have opted in some cases for higher energy intensity construction materials, especially the solar panels due to their payback in energy during the life of the building and recyclable building materials such as steel and aluminium. Composite timber-floor cassettes will replace the commonly used concrete floors to achieve gains in energy-efficient construction.
  60. 60. The building will have over 55% water self-sufficiency based on collection or rainwater and water reuse relying on built-in filter systems. In a country which captures less than 60% of its own fresh water needs and is currently reliant on its neighbor, Malaysia, for water, this is an especially important feature.
  61. 61. The EDITT tower will achieve almost 40% energy self- sufficiency through a system of solar panels.The 26-story high-rise will boast photovoltaic panels, natural ventilation, and a biogas generation plant all wrapped within an insulating living wall that covers half of its surface area. The verdant skyscraper was designed to increase its location’s bio-diversity and rehabilitate the local ecosystem in Singapore’s ‘zero culture’ metropolis.
