Seventeen full-scale bracing members made of double angles in A36 steel with welded stitches and end gusset plates were tested under large cyclic deformations representative of severe earthquakes. Three types of section configuration, conventional back-to-back, strengthened back-to-back, and boxed section configuration, were investigated. Early fracture due to local buckling is the common mode of failure of conventional back-to-back angles. Strengthening of conventional back-to-back angles by welding two inclined plates does not improve member response due to unsymmetric buckling.
