Abstract

A prestress-free self-centering energy-dissipative tension-only brace, including a self-centering mechanism, an energy dissipation mechanism, a force-limiting energy-dissipative mechanism, a high strength steel cable, and a sleeve. The self-centering mechanism includes a sliding end plate, a spring, and a connection rod. One end of the spring is connected and fixed to the inner wall of the sleeve, and the other end of the spring is connected with the sliding end plate. One end of the connection rod is anchored at the center of the sliding end plate, and the other end of the connection rod passes through a fixed end of the spring. The energy dissipation mechanism includes rotating shafts, rotating wheels, friction plates, chains, and a cross-shaped connecting piece.
