During the past century, the use of prestressing has increased tremendously. most important techniques of
prestressing is post-tensioning. In post tensioning two different method bonded and unbonded technic. Due to those
technic used in tendons/strands, thus overcome the more flexible and fast construction compare to RCC. Bonded and
unbonded system in stress, strength, deflection , bending moment and load balancing condition with solve by theoretical
and software. System present in graphical and designing data. Both methods applying and solve base on case-study. Also
find steel quantity span upto 10-40 meter use for both system, steel tendons in post-tensioning applications, is described.
At results of bonded and unbonded system which is best for minimum losses and construction suitability on given by
study data.
