Given: A six$-$story condominium structure is given as follows:

Rectangular plan $60ft125ft$

First story is $15$ ft high; each of other stories is $10$ ft high; flat roof

Exposure B and on flat terrain

Basic wind speed is $180$ mph

Lateral load resisting system: Concrete Moment Frame

Required:

Determine the external wind pressures for the main wind$-$force$-$resisting system of the building.

Determine the net wind pressures for the main wind$-$force$-$resisting system of the building.

Note: Use Directional Procedure which applies to structures of all heights.
