Ultimate wind speed of 170 MPH is equivalent to 132 MPH normal design wind speed according to 2014 Florida Building Code 5' Edition equation 16-32. 2) Formula for pressure developed by the wind, P=.00256(V)^2*(H/33)^0.29 Where: P = pressure in pounds per square foot V = wind speed in miles per hour H= height in feet above the ground surface (less than15 feet) 3) All of the Play Equipment Structure will be less than 15 feet in height. 4) All concrete shall be 3000-PSI minimum. 5) Soil Bearing Pressure 2000 PSF 6) Calculations were done by analyzing the worst case wind direction for each set of equipment. 7) Calculations were prepared in accordance to the 2014 Florida Building Code 5' Edition. Wind Design Data 1. Ultimate Design Wind Speed (MPH): 170 2. Occupancy category — Playground 3. Wind Importance Factor: 1.0 4. Wind Exposure Category: C 5. Internal pressure coefficient - NA (Open structure) 6. Enclosure Classification: Open 7. Components and Cladding (PSF): 36.0 to -36.0 8. Risk Category II Dale V.

The first is uplift (Vertical wind loading) and second is overturning (horizontal wind loading). Vertical Wind Loading In this condition we will compare the uplifting forces to the total pullout resistance of the foundation. The total uplifting force is equal to the wind pressure times the area in vertical direction. The total pullout resistance of the foundation is equal to the weight of the foundation plus the pullout resistance of the foundation from the adjoining soil. The weight of the foundation is equal to the volume of each support post's concrete tooter, times the density of concrete, times the number of support posts. The total pullout resistance of the foundation divided by the uplifting wind force is equal to the factor of safety. See Exhibit "A". The weight of the playground equipment was not included in our calculations. If the weight of the playground equipment was factored in, the factor of safety would be increased. Horizontal Wind Loading In this condition, we will compare the lateral forces acting on the Play Equipment to ensure that the structure does not overturn. This is accomplished by summing all of the forces acting on the structure about a single point "M". The sum of the forces about "M" from the weight of the structure, divided by the sum of the forces about "M" from the wind loading will equal the factor of safety. See Exhibit `B". Wind Load Pressures P=.00256(132)^2* (15/33)^0.29 =.00256(17,424)*(.8) = 35.68 For design purposes of this project, we will use a pressure of 36.0 pounds per square foot. v`� PEE ••„ (J� Dale V.
