Abstract
A dual-core self-centering brace apparatus is mounted to a building, and includes a first core member, at least one second core member, an outer sleeve disposed around the first and second core members, two inner abutment plates abutting respectively against two ends of the first core member, two outer abutment plates abutting respectively against two ends of the second core member, a plurality of tensioning members, and an energy-dissipating unit for retarding relative movement of the first core member and the outer sleeve. When subjected to an external force, the length of each of the tensioning elements is increased by an elongation amount, and the total length of the first core member and the outer sleeve is increased by an amount that is two times the elongation amount.
