Sigma-X Post Tension Floor

Sigma-X Post Tension Floor is based on equivalent frame method and enables to model any shaped slab, supporting walls and columns and any number of voids. Post tensioning tendons can be bonded or unbonded, banded or distributed. Slabs can be supported by internal and/or external columns, above or below the slab, or walls and can have holes/voids/drop caps. Sigma-X Post Tension Floor calculates losses due to creep, shrinkage of the concrete and relaxation, friction and wobble losses in the tendons.
