The prestressed members of a post-tensioned cable are classified as either bonded or unbonded according to the tendon bonding conditions. Trials and research that interested in a discrepancy between bonded and unbonded of different kinds of prestressed concrete members were rarely reported. This investigation aims to carry out a statistical comparison between the behaviours of bonded and unbonded post-tensioned prestressed members based on Meta-Analysis. To perform this, previous experimental studies on post-tensioned concrete members are reinvestigated, and statistical analysis is conducted using Meta-Analysis based on the standardized mean difference. The findings of the prior tests trials and current synthesized statistical analysis are implemented for better understanding the action of concrete members that include both bonded and unbonded post-tensioned prestressed reinforcements. The summary total effect size is recorded as -0.09 standard deviation with -0.805 to 0.757 confident interval and the p-value is 0.821. From the statistical point of view, the result is not statistically significant and no evidence indicates to reject the null hypothesis. So, there is not any function between the flexural strength and the conditions of different tendon bonding of post-tensioned prestressed concrete members. There is a lack of experimental information and investigations about the difference between bonded and un-bonded post-tensioning prestressed members. That means additional experimental work is needed to fulfil this lack.
