3.5 FAQs

1. Is it possible to determine the wind loads for the design of interior walls?

The Standard does not address the wind loads to be used in the design of interior walls or partitions

2. Do the doors and windows affects the wind pressure and suction?

Internal pressure changes occur because of the porosity of the building envelope. Porosity is caused by openings around doors and window frames, and by air infiltration through walls that are not absolutely airtight. A door or window left in the open position also contributes to porosity

3. What is the local suction? How does it affect the building?

Local suctions are most serious for wind at an angle (usually about 45 degrees) to the side of the building. Local pressure coefficients of -2.0 are not unusual, and in certain model studies values down to -5.0 have been measured over very small areas near corners projecting into the wind; this indicates the importance of proper fastening of roof coverings at such points.
