Abstract

In order to achieve in-plane buckling of the braces while subjected to compression, the brace sections at both ends are reduced by cutting the flanges to form plastic hinges at both ends. Finite element analysis was conducted to elucidate the effects of the design parameters on the brace behavior. On the basis of the numerical results, four specimens were designed and tested to study the hysteretic behavior and axial strength of the braces. The test results demonstrated that all specimens attained typical hysteretic behavior, achieving 4 to 5% rad of interstory drift angle, buckling in-plane, and rupture at the bracemid-length. As evidenced from the test results, the braces developed some strain hardening when subjected to tension. Moreover, the plastic flexural moment developed in the reduced section at both ends of the braces resulted in higher compressive forces than the buckling strength calculated based on pin-ended compression member. In summary, the braces designed by reducing section at both ends can achieve in-plane buckling and possess typical inelastic behavior.
