Abstract: Looking at the modern trend of construction, post-tensioning method is popularly used in commercial and residential sectors. The application of post-tensioning system is expanding because of its benefits over conventional method of construction, for example, more slender structural members, lighter in weight and smaller floor-to-floor heights. By employing post-tensioning method one can plan the most monetary and the safe structure. Prestressed concrete has been utilized as a replacement of reinforced concrete everywhere throughout the world for quite a long time. Presently, prestressed technology gives productive answers for different structural members and circumstances. The experimental results on the flexural behavior of post-tensioned concrete beams with bonded system are compared. Four rectangular post-tensioned beams were tested and analyzed. The beams were tested under single point monotonic loading condition and two point monotonic loading condition. The load-deflection behavior, stress-strain behavior and crack patterns are presented from the test results. Post-tension system effectively controlled deflection and crack due to the presence of tendons in addition to the reinforcing steel. All the four test outcomes were compared and they clearly showed good results over the conventional beams.
