多層筋違付架構の履歴挙動に関する実験的研究

Abstract

An experimental study is made on the elastic-plastic behavior of multi-story braced frame.Eight small models are tested under repeated horizontal load. Hysteretic behavior of columnsis investigated by analysing the output of strain gauges adapted to mid-height of columns.Test results provided that the axial force variation depends not only on the axial forcevariation of braces, but also on the alloted horizontal force of the column itself, and that thedeterioration of load carrying capacity of columns due to large deformation plays an importantrole if the column is slender. The maximum values of the axial force and the horizontalforce carried by a column are well predicted analytically.
