12 Summary of Brace Component Tests In-plane buckling deformation of the braces can be greater than 4 mm when the brace strain reached.2. Comparing the fabrication cost and the constructability, TH connection detail is recommended for the construction of the brace end-to-gusset joint for SCBF hybrid tests. TH
