Precast prestressed concrete brace system (RB Method) has been used for seismic strengthening for its simple and economical construction. The authors developed the new brace system using glulam members in place of concrete members. As for the bracing method using glulam, single brace type was already developed, therefore crossing brace type was proposed in this paper. For the purpose of investigating the structural behavior of the proposed system, half-scale concrete frame loading test was conducted, which was strengthened with the crossing brace system. As a result, the strengthened frame showed ductile lateral deformation until a drift of 1.0 %.
