HYSTERETIC BEHAVIOR OF MULTI-STORY BRACED FRAME

By 實 若林 and 道生 柴田

Abstract

The hysteretic behavior of multi-story braced frame is herein analyzed. The variation ofcolumn axial force is taken into consideration where the restoring-force of braces are evaluatedby the hysteresis function proposed by the authors. The restoring-force of a braced frameas a whole is expressed analytically as a function of the hystory of the relative displacementof the story.The restoring-force function is also formulated and proposed for the design use, based onthe parametric study where the brace slenderness, the column shape and strength and thearm-length of the horizontal force which is the function of the structural height and thehorizontal force distribution, are chosen as the parameters.The hysteretic behavior of multi-story braced frame is herein analyzed.
