OS2 Structural Safety

To limit the probability that the calculation of specified wind pressure or suction on exterior surfaces of buildings will not take into account all the factors that affect the expected maximum magnitude and distribution of wind pressure and suction on the exterior surfaces of buildings, which could lead to structural failure, which could lead to harm to persons.

To limit the probability that the calculation of wind load used for the design will not take into account the level of reliability appropriate for the use and occupancy, which could lead to structural failure, which could lead to harm to persons.
