Abstract：A new kind of self-centering and free-repair brace with friction damper is put forward in the paper, which the self-centering and the energy dissipating capacity are provided by the prestressed steel strand and the friction dampers respectively.In this thesis, the specimensare scaledto 0.6, as well as low cyclic loading tests with two designed friction conditions have been conducted to investigate the deformation performance, hysteretic characteristics, energy-dissipatedcapacity,plastic development,post-tensioned forcevariation and self-centering capacity. Simultaneously, numerical simulation towards the testing process has been carried out by adopting software ABAQUS, which results have been compared with that from the test. The researching results indicate that the new-typebrace can be installed feasibly and fleetly, as well as possessing favorable energy dissipating and self-centering capacity. All parts of the brace can maintain elastic during the loading process, the residual deformation is very small in later period of the loading process, stiffness of the brace remains relatively large. The installation of the brass sheets in friction dampers can avoid the maturing condition of friction interfaces as well asproviding stable energy friction capacity. Reduction of the cable forces in braces is very small after the loading process. Therefore, the braces can continue to work, achieving the design target of “self-centering and free-repair”, as well as reducing the repairing cost of the architecture.
