偏心 補强板의 挫屈解析

Abstract

本 論文은 四邊 單純支持된 補剛板이 一軸 壓縮荷重 下에 있을 때 Mindlin 平板理論을 導入, Ritz法에 依하여 彈性 挫屈解析을 수행하였다.

解析 結果値들은 이미 잘 알려진 挫屈 解析法에 依한 結果値들과도 잘 一致하며 特히 다른 方法과 比較하여 準解析的인 本 方法은 매우 작은 電算時間이 소요됨을 알 수 있었다.

In this paper, elastic buckling analysis of stiffened plates under uniaxial compaession with all edges simply supported is performed by Ritz method, using a mindlin plate theory and Timoshenko beam theory.

The present results show good agreement with those obtained with a simplified buckling analysis, especially compared with other methods, the present method is more effective in computing time for buckling analysis of a rectangular plate with stiffeners under simple loading and boundary condition.
