This research seeks to investigate the instantaneous effect of beam - column interaction on the axial compressive force in post-tensioned continuous concrete beam. Hypothetically, if a prestressed beam is connected to columns, the axial compressive force in the concrete of the beam caused by the prestressed force will be reduced due to the interaction between the beam and the columns during post-tensioning. Finite Element Approach usually has been considered the most accurate approach for structural analysis. However, Load Balancing Approach has commonly been used by structural engineers to analyze prestressed concrete structures. Load Balancing Approach converts the post-tensioned force to uniform distributed loads to be applied to models of concrete frames. The scope of work in this research involved making out two concrete frames as research subjects, developing frame models for SAP2000 prestressing approach and the Load Balancing Method. Static linear analysis was performed on both approaches to verify the hypothesis mentioned above.
