To reduce environmental burden in the field of building construction, this study aims to develop a composite steel-timber structure fixing a carbon and expand structure using timber. Since building structures and stadiums using reinforced concrete structure and steel structure can be substituted to composite steel-timber structure, it is aims to double the timber rate of year new building construction area. First, a composite steel-timber structure is investigated and classified building structure system which is composed of steel and glued laminated timber. Next, bending test and compressive test of the composite steel-timber members are conducted to grasp basic structural performance. Finally, a design method of the composite steel-timber structure using buckling-restrained knee braces is proposed on the previous experimental tests. A trial design is conducted where applicability of the design method is shown.
