Basic Calculation to retrofit The Kauffman Art Center with Flexible PSCs

This page describes all calculation and assumptions in calculating Kauffman art center retrofit the top roof

To measure hatched area in Fig. 1 Google Earth distance measurement has been used.

• All measurements repeated three times and averaged to minimize the error.
• Google Earth distance measurement tool does all measurement as level plane. This measurement is not accurate for inclined planes like roof.
• to minimize the error angle of the roof was measured and considered in calculations (Fig. 2).
• Top right and left red hatched area in Fig. 1 considered as triangles
• Bottom right and left red hatched area in Fig.1 each estimated to a half circle

1. top left:
   • base= 63 m
   • leveled length (Google Earth)= 31 m
   • inclined length (considering 45 degree angled) = 43.84 m
   • Top left area= (63 m)*(43.84 m)/2 = 1381 m^2
2. top right
   • base= 45.2 m
   • leveled length (Google Earth)= 27 m
   • inclined length (45 degrees) = 38.18 m
   • Top right area= (45.2 m)*(38.18 m)/2= 863 m^2

1. bottom left
   • diameter=30 m
   • half circle area= (pi*15^2)/2=350 m^2
2. bottom right
   • diameter=39 m
   • half circle area= (pi*19.5^2)/2=597 m^2

Total area= 1381 + 863 + 350 + 597 = 3191 (m^2)
