An example problem on wind load calculation according to NSCP 2010 ;)

A 20-meter-high square-plan five-storey building with flat roof and 4m-high floors, located in Makati CBD, has sides of 10 meters length each, and a large open front door on the first floor that is 2m x 2m in dimension. Assuming that G = 0.85 and that torsion is negligible,
  1. Show how this maybe is an open, partially enclosed, or enclosed building.
  2. Determine the internal pressure coefficients.
  3. Determine the external pressure coefficients for the design of main girders and shear walls.
  4. Determine the base reactions due to along-wind loads acting on the front wall of the building.
