Dome Prestressing Description of Tendon Arrangement

There will be three layers of Tendons, are in each of the three directions. Each group of Tendons will take 1/1.5 times the required prestressing force. For check on this see roof plane on sheet 2. Red cross hatching indicates areas where 2 groups of tendons are anchored. Single red lines indicates where only one group of tendons are anchored. 

Each anchor zone is divided into 12 equal areas. A of these areas have one tendons group anchored where each group will take 1/12 of the prestressing force. Also V2 the anchor areas where 2 groups of tending area will take 1/6 of the prestressing force with each direction contributing 1/12. 

5 times required prestressing of force is furnished by all the tendons, therefore the computed prestress force will be divided 1.5 to act read prestress Assumption and Criteria for design.
