Abstract

This paper proposes a turnbuckle brace with Cu-Al-Mn superelastic alloy for reducing residual deformation. Firstly, mechanical properties of Cu-Al-Mn superelastic alloy bar is obtained from coupon test. Secondly, mechanical behavior of screw joint with threaded superelastic alloy bar is examined from cyclic loading test. Then, design method of screw joint with the superelastic alloy is proposed. Finally, an experimental verification is conducted on the turnbuckle brace to which superelastic alloy bar is connected by the screw joints. From the experimental result, it is demonstrated that residual deformation of the turnbuckle brace with the superelastic alloy hardly occurs after loading.
