TALL BUILDINGS DEFINITION

A tall building is classified as any building that is significantly taller than its local context and/or has a significant impact on the skyline.

Advantages of Tall Buildings

Provides room for a large proportion of open space for creating natural surroundings. The economy in a profit of less land for construction. Permits better day-lighting and greater flow of air. Presents a pleasant panoramic view of the city.

The main problem driving the so-called “heat-island effect” is tall buildings. They create urban canyons, blocking winds from cooling things down, and locking in heat. Urban centres can range as much as 22 F warmer than nearby rural areas.

The top 10 tallest buildings in the world includes Burj Khalifa, Shanghai Tower, Makkah Royal Clock Tower, Ping An Finance Center, Lotte World Tower, One World Trade Center, Guangzhou CTF Finance Centre, Tianjin CTF Finance Centre, CITIC Tower, and Taipei 101.

Generally a high rise can be anything above ten stories, above 40 stories is called a skyscraper, I guess above 100 stories is a mega tower?

“The building is tall”, refers to the height of the building from the ground to its roof. “The building is high”, may refer to the altitude of the building — its position relative to geographic features, such as sea level, or the base of a mountain. For example, you could say, “The building is high on the mountain.”

The sail effect of a high-rise building exposed to direct sunlight can cause hot spots behind the building; choice of building material and use of shadowing can reduce this effect. The wind-tunnel effect can cause cold paths, especially if the area is shaded.

Unbeatable views. The higher you are, the more you can see. Skyscrapers provide inhabitants with those end-of-day views to savour and ponder as they wind down with a glass of wine or a cold one.

Living on a higher floor offers advantages like increased natural light and better ventilation. However, it also means heightened exposure to the elements. In scorching summers, the excess sunlight can turn your home into an oven, while chilly winters bring cold drafts that may require additional heating.

What are two main problems when building tall buildings? ›

1. Structural complexity: Tall buildings require advanced engineering and construction techniques to ensure stability, safety, and durability. 2. Cost: Building tall structures can be expensive, requiring significant investment in materials, technology, and skilled labor.

Increases in heat within urban centers increases the length of growing seasons and decreases the occurrence of weak tornadoes. The UHI decreases air quality by increasing the production of pollutants such as ozone, and decreases water quality as warmer waters flow into area streams and put stress on their ecosystems.”

Poorly designed and constructed buildings use more energy, increasing the demand on energy production and contributing to global warming. Reducing energy use in buildings is one of the most important ways to reduce humans' overall environmental impact.

The term "skyscraper" was first applied to buildings of steel-framed construction of at least 10 stories in the late 19th century, a result of public amazement at the tall buildings being built in major American cities like New York City, Philadelphia, Boston, Chicago, Detroit, and St. Louis.

Outriggers are rigid horizontal structures designed to improve building overturning stiffness and strength by connecting the building core or spine to distant columns. Outriggers have been used in tall, narrow buildings for nearly half a century, but the design principle has been used for millennia.

Three major components that structural engineers can work with in tall building designs are mass, stiffness, and damping. Usually mass and stiffness are the most common elements that are modified, but also damping can be used to enhance building performance.

Skyscrapers are specifically designed to withstand extreme weather and geological events such as high winds or earthquakes. Allowing for movement helps these tall buildings sway and alleviate wind pressure, minimizing any fall risk.
