What is a Skyscraper Project
Skyscraper is a tall continuously habitable building having multiple floors. Modern sources define skyscrapers as being at least 100 meters (330 ft) or 150 meters (490 ft). Modern skyscraper are built with steel or reinforced concrete frameworks and curtain walls of glass or polished stone. They use mechanical equipment such as water pumps and elevators.
Types of Structural Systems in High Rise Buildings
Braced-frame structural system
This structural system refers to cantilevered vertical trusses that resist laterals, loads primarily diagonal members together with girders, and forms the web of the vertical truss. This is more used in steel construction and is suitable for multistory building in the low to mid-height range.
Rigid-frame structural system
In this kind of structure, beams and columns are constructed monolithically to withstand moments that are imposed due to loads. A rigid-frame system is more suitable for reinforced concrete buildings.Although this system may also be used in steel construction, the connections will be costly.
Wall-frame structural system
The wall-frame or dual system consists of a wall and frame that interact horizontally for a stronger and stiffer system. In this system, the walls are usually solid and can be found around elevator shafts, stairwells and/or at the perimeter of the building.
Shear Wall system
This kind of system is a continuous vertical wall that’s constructed from reinforced concrete or masonry wall. Shear walls are great at withstanding gravity and lateral loads, as well as acting as narrow-deep cantilever beams. This is commonly constructed as a core of Building.
Core and Outrigger structural system
This structural system is designed for improving building overturning stiffness and strength by connecting the core or spine to closely spaced outer columns. Basically, outrigger systems function by tying together two structural systems—a core system and a perimeter system and then render the building to behave as similar as a composite cantileve.
Skyscraper Global Projects
Burj Khalifa, Dubai, United Arab Emirates This is the worlds tallest structure with a total height of 829.8 m (2,722 ft, or just over half a mile) and a roof height (excluding antenna, but including a 242.6 m spire) of 828 m (2,717 ft). Burj Khalifa was de- signed to be the centerpiece of a large-scale, mixed-use development to include 30,000 homes, nine hotels, 3 hectares (7.4 acres) of parkland, at least 19 residential skyscrapers, the Dubai Mall, and the 12-hectare (30-acre) artificial Burj Khalifa.
