Post Tensioning Slab Tributary Area calculation Load Data preparation for every column P.S. for - Corner column - Internal column - Edge column M odel creation & Analysis check also, - Area of edge reinforcement - Number of Tendon - Deflection check - Ultimate check - Service check - Axial pre stress - Profile points Slab Edge Reinforcement check - Perpendicular to edge - Parallel to edge based on the requirements. Number of Tendons contribute should be checked. Column stiffness contribution should be checked. Slab thickness, friction losses due to stressing in ends like Pan End or Live End. In Moment Joint we should be taken half of the slab of self weight , Live end & perimeter line end. Near corel area, Tendon profile should be placed High points & straight.
