Brace member

Abstract

A brace member includes a plastically deformable core member, a buckling restraining member through which the core member extends, a cap sleeve in which a first end portion of the core member and a first end portion of the buckling restraining member are disposed, a cap-sleeve crevice disposed on the cap sleeve so as to protrude toward a side opposite to a side on which the core member and the buckling restraining member are disposed, a reinforcing member in which a second end portion of the core member is disposed, and a reinforcing-member crevice disposed on the reinforcing member so as to protrude toward a side opposite to a side on which the core member is disposed. The reinforcing member surrounds a predetermined area of the buckling restraining member extending from a second end surface on the second side in the longitudinal direction.

1 . A brace member, comprising:
 a core member;   a buckling restraining member through which the core member extends and that restricts out-of-plane deformation of the core member;   a cap sleeve in which a first end portion of the core member on a first side in a longitudinal direction and a first end portion of the buckling restraining member on the first side in the longitudinal direction are disposed;   a cap-sleeve crevice disposed on the cap sleeve so as to protrude toward a side opposite to a side on which the core member and the buckling restraining member are disposed, the cap-sleeve crevice serving as a joint for installing the brace member on an architectural structure;   a reinforcing member in which a second end portion of the core member on a second side in the longitudinal direction is disposed; and   a reinforcing-member crevice disposed on the reinforcing member so as to protrude toward a side opposite to a side on which the core member is disposed, the reinforcing-member crevice serving as a joint for installing the brace member on the architectural structure,   wherein the reinforcing member surrounds a predetermined area of the buckling restraining member extending from a second end surface on the second side in the longitudinal direction.   
     
     
         2 . A brace member, comprising:
 an core member;   a buckling restraining member through which the core member extends and that restricts out-of-plane deformation of the core member;   reinforcing members disposed individually on two ends of the core member in a longitudinal direction; and   reinforcing-member crevices disposed individually on the reinforcing members so as to each protrude toward a side opposite to a side on which the core member is disposed, the reinforcing-member crevices serving as joints for installing the brace member on an architectural structure,   wherein each of the reinforcing members surrounds a predetermined area of the buckling restraining member extending from a corresponding one of end portions of the buckling restraining member in the longitudinal direction.   
     
     
         3 . The brace member according to  claim 1 ,
 wherein an inner diameter of the reinforcing member in the area in which the reinforcing member surrounds the buckling restraining member is constant in the longitudinal direction, and   wherein an outer diameter of the reinforcing member in the area decreases toward a center of the buckling restraining member in the longitudinal direction.   
     
     
         4 . The brace member according to  claim 2 ,
 wherein an inner diameter of the reinforcing member in the area in which the reinforcing member surrounds the buckling restraining member is constant in the longitudinal direction, and   wherein an outer diameter of the reinforcing member in the area decreases toward a center of the buckling restraining member in the longitudinal direction.
