as specified in the tables shown below. The two sets of values underneath the Basic Wind Speed represent
the down/uplift forces. The positive values are the down-forces, and corresponds to the force acting towards
the surface. On the other hand the negative values correspond to the uplift force, and acts away from the
surface. Both of these values are crucial to the loading analysis of a particular structure, and both must be
considered. Refer to figure 6-3 in the ASCE 7-05 for more information.
