How can high-rise buildings withstand typhoon disasters?

Every summer, typhoons wreak havoc, causing varying degrees of disasters in areas such as Guangzhou and Macau, especially in many high-rise buildings near the seaside where glass curtain walls, doors, and windows are severely damaged. How to better resist typhoons has become a question that every building curtain wall, door and window company must consider.

How can high-rise buildings withstand typhoon disasters?

How should high-rise building structures be designed in areas frequently affected by typhoons?

Strictly pay attention to structural calculations and prioritize structural safety levels. The safety factor of curtain wall components must be increased during structural calculations to ensure that each component has sufficient strength margin to cope with the impact and damage caused by super typhoons.

Calculation of each component:

A、 Surface material: Under the premise of improving the safety factor, strict calculation is required to ensure the safety of glass.

B、 Keel: The minimum design thickness and local thickening design of the main load-bearing aluminum profile must meet the requirements of the connection structure.

C、 Structural adhesive: Try to use ultra-high performance silicone structural sealant to improve the safety factor of the curtain wall.

D、 The design of connection nodes must meet the construction requirements to ensure reliability and safety.

What elements should be considered in the design of high-rise building complexes?

When multiple buildings, especially high-rise buildings in clusters, are closely spaced from each other, it is advisable to consider the group effect of wind interference; Generally, the shape coefficient u of individual buildings can be multiplied by the mutual interference amplification coefficient, which can be determined by referring to similar experimental data. If necessary, it is advisable to obtain it through wind tunnel tests.

When a building complex, especially a high-rise building complex, has a close distance between buildings, the local wind pressure in certain parts of the building will significantly increase due to the mutual interference of vortices, which should be taken into account during design. For important high-rise buildings, it is recommended to consider the interference factors of Zhoutian buildings in wind tunnel tests.

After a typhoon, doors and windows are severely damaged and need to be replaced. How should I choose new doors and windows?

If the doors and windows are severely damaged and need to be renovated and installed again, it involves the selection of windows. Firstly, the material of the windows is very important. If the home is located in a relatively spacious area, especially in a coastal open sea view house, the window material selection during decoration must be very sturdy, preferably with earthquake resistance, typhoon resistance and other performance.

There are a total of nine levels of wind pressure resistance for glass windows and glass curtain walls, and the higher the level, the better the wind pressure resistance performance. Therefore, when choosing windows, people should choose glass windows with higher wind pressure resistance levels. If it is located at a wind outlet and in a high-rise building, it is best to choose doors and windows with a wind pressure resistance rating of 5 or above.
