繰り返し軸方向力を受ける部材の挙動に関する一実験

Abstract

The structural behavior of a braced frame greatly depends on the restoring-force characteristicsof the bracings themselves. A bracing is primarily subjected to the axial force, tensile and/orcompressive. This paper presents the results of an experimental study on the behavior of steel barsunder alternate cyclic axial loading. In the first series of tests, bars are monotonously compressed, the main attention being paid on their post-buckling strength. In the next series, bars are subjectedto a number of cycles of compession and tension with gradual increase of the axial displacementamplitude. The axial load-displacement relations are recorded by an "Autograph" testing machine.
