A prestressed precast concrete brace system was proposed by the authors in 2001 and this study introduces a revised brace system using concrete filled tube and precast fiber reinforced concrete to enhance its deformation capability and aesthetics. Two half scale portal frames were constructed based on the old Japanese building standard and strengthened with two kinds of brace system without using rebar nor bolt anchorage; one made of precast fiber reinforced concrete and the other made of concrete filled tube. Each brace was a single line element and easily placed in a existing frame. Braced frames showed more than 70% increase in shear capacity and enhancement in ductility. It was also shown that the existing design equations for axial strength of a brace, shear strength of column-beam joint, and bearing strength can be applied to design the proposed brace system.
