Shape-memory alloy stranded wire self-centering frictional buckling-restrained brace
The invention provides a shape-memory alloy stranded wire self-centering frictional buckling-restrained brace, and belongs to the technical field of disaster prevention and shock absorption. The shape-memory alloy stranded wire self-centering frictional buckling-restrained brace is mainly composed of a linear steel plate inner core, an inner steel sleeve, an outer steel sleeve, friction plates, high-strength bolts, shape-memory alloy stranded wires, a left end plate, a right end plate, backing plates and anchorage devices; the two ends of the linear steel plate inner core are hinged to stiffening ribs which are connected to the left end plate and the right end plate respectively. The inner steel sleeve serves as a peripheral restriction steel sleeve to be arranged outside the linear steel plate in a sleeving mode, the linear steel plate is arranged in the inner steel sleeve in an opposite angle inclined mode, and a certain gap exists between the inner steel sleeve and the linear steel plate inner core. The inner steel sleeve is connected with the right end plate, the outer steel sleeve is connected with the left end plate, the friction plates are installed between the mutually nested portions of the inner steel sleeve and the outer steel sleeve through the high-strength bolts, and the shape-memory alloy stranded wires are anchored between the inner steel sleeve and the outer steel sleeve through the anchorage devices after being pre-stretched. By means of the shape-memory alloy stranded wire self-centering frictional buckling-restrained brace, the problem that due to the fact that for a conventional brace, excessive residual deformation occurs under the action of a large earthquake or an intermediate-earthquake, the post-earthquake maintenance and reconstruction cost is increased is solved.
