What is High Rise?

A highrise building is a structure that has more than 10 floors and is designed to accommodate different types of activities, such as living, working, shopping, or leisure.

How to distinguish between a skyscraper and a highrise: While there is no universally agreed definition, some general criteria can be used to differentiate these two types of tall buildings. According to the Council on Tall Buildings and Urban Habitat (CTBUH):

A skyscraper is a building that is at least 150 meters or 500 feet tall, has a significant impact on the skyline, and functions as a landmark or icon for its city.

A highrise, on the other hand, is a building that is between 35 and 100 meters or 115 and 328 feet tall, has a relatively modest impact on the skyline, and functions as a normal part of the urban fabric.

Skyscrapers and highrises have different design challenges, environmental impacts, and social implications, and they reflect different economic and cultural contexts.

Advantages: Highrise buildings offer many advantages, such as efficient use of land, reduced transportation costs, increased density, and enhanced views. For example, highrise buildings can save up to 80% of land area compared to low-rise buildings, and can reduce the travel time and energy consumption of residents and workers.

Challenges: Highrise buildings also pose some challenges, such as structural stability, fire safety, wind loads, and environmental impact. For instance, highrise buildings need to withstand earthquakes, hurricanes, and other natural disasters, and have adequate fire protection systems and evacuation routes.

Highrise buildings also generate more heat, noise, and air pollution than low-rise buildings, and may affect the microclimate and natural ventilation of the surrounding areas.

Design Issues: Highrise buildings require careful planning, design, construction, and maintenance to ensure their functionality and sustainability. Highrise buildings should follow the principles of green architecture, such as using renewable energy sources, minimizing waste generation, maximizing natural lighting and ventilation, and incorporating green spaces and landscaping.

What is High Rise Core?

The core of a highrise building is the central structural element that supports the weight and stability of the tower.

Components: It usually contains the elevator shafts, stairwells, mechanical and electrical services, and other essential functions.

Design Impacts and Functions:

A highrise building core is the central structural element that supports the weight and stability of the tower.

The role of the core is to provide structural integrity, efficiency, safety, and aesthetics to the building, as well as to reduce the construction cost and time.

A well-designed core can optimize the floor space, enhance the natural lighting and ventilation, and reduce the energy consumption of the building.

Basic Types of Building Core:

There are different types of building cores that serve different functions and purposes. The core can be located in various positions within the building, such as in the center, at the perimeter, or at one or more corners. The location and shape of the core affect the structural stability, efficiency and flexibility of the building design. Some common types of building cores are:

Box core: A rectangular or square core that occupies the center of the building. This type of core provides good structural rigidity and allows for flexible floor layouts around it. However, it may reduce the natural light and ventilation in the interior spaces.

Tube core: A cylindrical or polygonal core that surrounds the perimeter of the building. This type of core creates a strong and stiff structure that can resist lateral forces such as wind and earthquakes. It also maximizes the floor area and the views from the windows. However, it may limit the flexibility of the floor plans and increase the cost of construction.

Corner core: A core that is located at one or more corners of the building. This type of core creates a diagonal bracing system that enhances the stability and strength of the structure. It also allows for more natural light and ventilation in the interior spaces. However, it may reduce the floor area and create irregular floor shapes.
