Buckling Restraint Brace with assembly type steel restraint material

摘要

The present invention relates to a buckling inhibited brace with a steel assembled-type double reinforcing bar capable of solving most problems of dimension instability and partial buckling by not filling a reinforcing bar with concrete, and flexibly respond to situations by adjusting the length of a yield section through a double reinforcing bar structure depending on required strength. The buckling inhibited brace with a steel assembled-type double reinforcing bar comprises: a core deformed at a yield point by absorbing energy when a repeated load is applied by an earthquake; a reinforcing bar suppressing buckling by accommodating the core therein and having both ends restraining both ends of the core; and a pair of connection members connecting the both ends of the reinforcing bar with a framework of a building. The reinforcing bar can adjust the length of the yield section depending on required strength by adjusting a gap between both ends of the first and second reinforcing bars.
