Experimental Studies on the Elastic-Plastic Behavior of Braced Frames under Repeated Horizontal Loading. Part 1 Experiments of Braces with an H-shaped Cross Section in a Frame

Abstract

An experimental study is conducted to obtain the hysteretic characteristics of the brace itself in a braced frame under repeated loading. Braces with an H-shaped cross section are tested in a single or a double bracing system. The effects of the slenderness ratio, the buckling plane and the local buckling are investigated. Furthermore, the fundamental properties of a brace for the formulation of the hysteretic characteristics under repeated loading are extracted
