Abstract:
hybrid frames contain precast concrete elements beams and columns that are connected byunbonded post -tensioning steel and partially debonded mild steel reinforcing bars where both types of steel contribute to the overall moment resistance of the connection since the inelastic deformaion is concentrated at the beam-column interface the seismic response of a frame system can be accurately predicted using one dimensional beam elements in this research effect of contribution of post tensioning tendons on the nonlinear response of hybrid frame has been studied and a new distribution of post tensioning in the height of structures proposed.
