Abstract：
The external post-tensioning techniques used for structures retrofitting are analyzed comprehensively. The design and calculating methods of RC flexural members strengthened with external tendons are discussed. Meanwhile, the general profiles of external tendons and the joint detail are also presented. Moreover, the construction techniques of using post-tensioning to strengthening frame beams are introduced. Post-tensioning is also used as seismic retrofitting techniques for masonry structures in foreign countries and the related principles and methods are also introduced briefly.
