Snow load

Snow load

Base snow load calculation:

Snow load is the snow weight that is less than 2% likely to exceed in one year based on statistical data available in the area.

The snow load calculation will be based on the sixth section of the National Building Code of Iran.

Earthquake load

Earthquake load

Buildings and their components shall be designed and constructed for earthquake impacts in accordance with the National Building Code of Iran and earthquake loads. The design-based earthquake is an earthquake that is less than 10 percent likely to occur within 50 years of the building’s useful life. Also, buildings of high importance or taller than 50 meters or more must meet the specific criteria for the impact of an “earthquake” level of operation that is more than 99.5 percent likely to occur in 50 years.

According to national building rules and regulations, Chapter Six, Earthquake Side Effect Sections Affecting Non-structural Components article 6-7-2-8 and figure 6-7-7 above Article, Connections of prefabricated structural elements are considered one (1) along each line.

  • Building with very high importance factor(I = 1.5)

1-      Building with very high importance factor (I = 1.5)

Buildings that are definitely in use after the earthquake Such as hospitals, firefighting, posts, and telecommunication centers, terminals, power plants, chemical warehouses, govern orates, and municipalities.

  • Building with high importance factor(I= 1.4)

Schools, universities, hostels, military centers, prisons, and museums

  • building with a medium important factor (I=1.2)

Stadiums, cinemas, theaters and seminar centers

  • building with a Low important factor (I=1.1)

Residential homes, commercial buildings, hotels, etc.

Wind load

Wind load

Buildings and structures and all their components and coatings shall be designed and constructed for wind effect, in accordance with the requirements of the National Building Code of Iran (Chapter on Wind Loads).

What is wind load:

Wind load is the load, in pounds per square foot, placed on the exterior of a structure by wind. This will depend on: The angle at which the wind strikes the structure. The shape of the structure (height, width, etc.)
