Frontiers of Structural and Civil Engineering 2018, Volume 12, Issue 1,   Pages 148-162 doi: 10.1007/s11709-016-0375-5

Abstract: Finite element modeling of the HSS braces that utilizes the true stress-strain curves produces hysteresisTrue stress-strain curves are obtained from coupon tests or stub-column tests while utilizing an exponentialfunction or strain hardening rule with a trial and error procedure to obtain the hysteresis behaviorIn the current study, the true stress-strain curves are directly obtained from tests on stub-columnsResults indicate that the stress-strain curves for these braces are not unique.
