面内に曲げと圧縮力を受ける制振鋼板の座屈耐力に関する研究

Abstract

The Purpose of this paper is to investigate the buckling strength of high-damped steel plates, which can be influenced by the shearing behavior of core polymer. According analytical investigation, simplifed approximate formulas are proposed to estimate the buckling strength of high-damped steel plate, of which 4 edges are simply supported, under compessive force and bending moment. The estimation of post-buckling strength of high-damped steel plates are attained by introducing new parameter on width-thickness ratio, which is derived from the approximate formulas on the buckling strength. The estimation by the proposed method showed good agreement whith experiment results.
