Chapter 7
The effect of the wind on buildings and facilities
1.7. The field
This chapter of the Code is specified in indicating the effect of the wind that should be considered when
designing buildings and facilities either as one unit or its components and parts individually.
1.1.7. Buildings and facilities should be designed to stand still against the effect of wind.
2.1.7. Designing a building should consider the effect of wind depending on the following:
1. The building as one unit.
2. Parts of the building as ceiling, walls, etc.
3. Windows, building’s front, etc.
3.1.7.When calculating the effect of wind loads on the walls, partitions and all the building’s parts
affected by pressure or withdrawal on both sides, the designed wind pressure on these parts is
considered the total of pressure or withdrawal on the first side and pressure or withdrawal on the
second side.
4.1.7. When calculating the effect of wind on the normal building and facilities, we use the method
mentioned in (3.7), for building and facilities with certain specialties like:
1. Buildings and facilities with unusual shape or design.
2. Buildings and facilities that might vibrate due to its hanging ceiling etc.
So the following is recommended:
1. Knowing the values of the maximum average of wind speed per hour from the nearest
metrological center to the building for all the available years of data with specifying the height of
calculation of wind speed and the nature of calculation area.
2. The main wind pressure is calculated using the available information in the previous period and
analyzing it using the statistical method of maximum values to get the wind speed and the main
wind pressure.
3. Using the previous lab experiments applied on similar buildings, or the experiments done on the
model of the building itsel
