Post-Tensioned concrete structures can be analyzed using different methods. One of these methods is the load balancing method introduced by T. Y. Lin. This method, unlike conventional stress methods, assumes pre-stress as a form of loading that counteracts the dead loads, live loads and service loads. Basically, the prestressing force is resolved into vertical and horizontal components and then the structure is analyzed as an ordinary loaded structure. The aim of this study is to investigate the effect of horizontal component of prestressing force in frames of different lengths. The horizontal component in beam-like structures will not affect the vertical reactions of the supports or bending moments of the beam. However, neglecting this component in frames can cause significant difference in the actual results. SAP2000 was used to analyze the frames by applying prestress forces directly and then by using balancing loads with and without considering the horizontal component of the prestressing force.
