High-rise buildings are buildings that are taller, which naturally also weighs more than regular buildings. These buildings are primarily always found in cities and have some means of transportation inside of the building, which is usually elevators and more traditionally, stairs. Most buildings have both.
High-rise buildings are generally built for the use of apartments, office buildings and hotels. Hotels are usually one of the tallest constructed, high-rise buildings. Some educational and retail facilities, such as universities and malls, are also listed as high-rise buildings.
In the modern world, we live in today; high-rise buildings are priced according to what they’re built for. For instance, a space that is specifically reserved for hotels, will cost a lot more than the fees of, say that of a college as there is more detail to pay attention to. Choosing the right location, as well as the interior, is also extremely important.
The Structural Systems of High-Rise Buildings
High-rise buildings are constructed in such a way to support extremely heavy loads. Nevertheless, the same systems that are used for low-rise buildings, also get used in these types of buildings.
Since these buildings are incredibly tall, they are built to be able to carry heavy gravity loads that are structured vertically. It also requires the presence of lateral loads in its structure, to be able to resist earthquakes and severe weather conditions, such as strong winds, hurricane storms and more.
To determine the weight of a high-rise building and implement the necessary fundamentals and structure to be able to withstand severe weather conditions, it usually makes up about 50 pounds per one square foot, which when multiplied by the entire surface area of the building, is quite substantial.
When focusing on coastal areas and towns, there is a lot more to take into consideration when planning and structuring the perfectly adequate high-rise building. Weather conditions on the coast is a lot different from that of weather conditions inland.
The Importance of Weight in High-Rise Buildings
The fact that hurricanes, tsunamis and typhoons occur more and more with the passing of time in the last century, the way these buildings are designed, and structure is of utmost importance. They require up to 120 pounds, on average, per square metre. Depending on how strong the wind is, the building must be heavy enough to withstand it completely. Buildings can thus weigh 380 to 400 pounds per square metre. It is usually only the case in areas where typhoons and severe hurricanes occur annually.
If wind causes buildings to bend, starting from the top, with the pressure of the wind causing the vortex to break away and as a result, cause it to sway, the structure of the building does not meet the performance criteria that such structures must meet, making it unsafe altogether.
