![]() ![]() ![]() These maps provide basic wind speeds that are directly applicable for determining pressures for strength design. ![]() For this edition (05), the ASD wind-load factor is 1.0 and the strength design wind-load factor is 1.6.ĪSCE 7-10 uses three different basic wind speed maps for different categories of building occupancies. The wind-load factor is then applied to determine the design wind pressure. Note that these importance factors only depend on the type of building, not where the building is located. For each building risk category an importance factor is applied. Found hereĪSCE 7-05 uses a single basic wind speed map. Found hereĪSCE 7-05 Minimum Design Loads for Buildings and Other Structures.
