Abstract
A seismic-incurred-rupture-resistant deformation-recordable buckling-restrained brace is disclosed. A core plate is disposed in the concrete filled steel tubular outer sleeve, and an end portion of the core plate is provided with a core plate stiffening rib. A brace deformation recording device includes two toothed racks, a ratchet gear, a first cord spool, and a second cord spool. The two toothed racks are fixed on the core plate stiffening rib, and ratchet pawls in the length direction thereof face opposite directions. The ratchet gear is fixedly connected to the concrete filled steel tubular outer sleeve. The ratchet gear is disposed between the two toothed racks. A tooth on the ratchet gear is engaged with a ratchet pawl. The first cord spool is fixed on the ratchet gear. The second cord spool is fixed on the core plate stiffening rib.
