鉛直荷重を受ける剛接合単層ラチスドームの弾塑性座屈性状

抄録

The purpose of this paper is to estimate the elasto-plastic buckling load of rigidly jointed single-layer latticed domes under vertical load. The value of As is adopted as to the geometric parameter of the domes. An elasto-plastic buckling analysis is carried out. Then the relation between the elasto-plastic buckling behavior of the domes under uniform load and the value of As is examined. In addition, the same analysis is carried out in the case of under one-side uniform load and under concentrated load. As a result, the elasto-plastic buckling load of the domes under vertical load is estimated by the linear buckling load of the domes or member yield load.
