Comparison of Bonded and Unbonded Systems in PT Slab

The design of moment capacity maximum for bonded and unbonded system for post tension slab using ACI 318M-19 and calculation in software ADAPT BUILTDER 2019 by compare moment capacity maximum results in this research paper. From this study, for length span, number of strands, loading in the same case. So, the result is shown that for bonded system if the ratio of length’s span is increased, it makes moment capacity maximum also increased. On the other hand, the result is shown that for unbonded system if the ratio of length’s span is increased, it makes moment capacity maximum decreased. In the conclusion, moment capacity maximum of bonded system has economic than
unbonded system.
