The core platcs of buckling‐restrained braces are often required to yield at a small story deformation angel.Reducing the core plate cross‐sectional area could decrease the yield strength,but this also decreases the axial stiffness.The use of low-yield-point steel is limited due to limited variety.The yield strength can be decreased wwhile maintaining its axial sriffness by reducing the core plate cross-sectional area and simultaneously increasing its end thickness.The adjustment of the yield strength and axial stiffness is also possible.In this paper,the effect of the yield strength and axial stiffness adjustment is examined using simplifed calculation formulae.Tests are performed to verify the validity of the formulae.The energy absorption performance and failure mode characteristics are analyzed based on the test results.
