Abstract
Previous studies indicated that the external prestressing tendons can effectively improve the deformability and bearing capacity of RC frames. However, how to utilize the external prestressing tendons to prevent the increase of deformation of the structure with catenary action in the process of collapse needs further study. Using an analytical method for the stress variations of external prestressing tendons based on structural deformation, the deflection and stress of beam-column sub-structureunder the failure of RC column during elastic and plastic stages are studied, the calculation of ultimate bearing capacity considering catenary action are also presented which provide a basis for collapse-resistant design of beam-column sub-structures.
