Comparative Study Of Bonded & Unbonded Post-Tensioning Beams In Building

Abstract

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 technical. Due to those technical 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 up to 10-40 meter use for both systems, steel tendons in post-tensioning applications, is described. Final draw the design of bonded and unbonded beam with suitable anchoring location. At results of bonded and unbonded system which is best for minimum losses and construction suitability on given by case study data.
