Abstract

Static loading tests of displacement restraint PC steel bar brace, which acts as a central pillar when the displacement reaches a given value, were conducted with and without disc springs at the ends. Then the brace was loaded to the ultimate broken state. The behavior of the brace ends, hysteretic characteristics and axial forces acting on the four PC steel bars were confirmed in these tests. Stress distributions in the gusset plate and rib plates at the brace end were analyzed to determine the end rigid zone length when the brace was replaced with a linear element model.
