Wind Pressure as given by ASCE 7 Solution

Follow our step by step solution on how to calculate Wind Pressure as given by ASCE 7?

FIRST Step Consider the formula

p = q \cdot G \cdot C ep - q i \cdot GC pt

Next Step Substitute values of Variables

∴

p = 20pdl/ft² \cdot 1.2 \cdot 0.95 - 15pdl/ft² \cdot 0.91

Next Step Convert Units

∴

p = 29.7633Pa \cdot 1.2 \cdot 0.95 - 22.3225Pa \cdot 0.91

Next Step Prepare to Evaluate

∴

p = 29.7633 \cdot 1.2 \cdot 0.95 - 22.3225 \cdot 0.91

Next Step Evaluate

∴

p = 13.6167000835524Pa

Next Step Convert to Output's Unit

∴

p = 9.15000000000003pdl/ft²

LAST Step Rounding Answer

∴

p = 9.15pdl/ft²
