摘要: 应用精确的球壳屈曲分支方程和Galerkin法,研究固定夹支半球壳承受风型荷载时的稳定性,确立了接近分支点变形的屈曲模态,所得屈曲临界值为科学设计提供了依据.

Abstract: The stability of clamped hemispherical shells under wind-type loads is studied by applying the exact buckling bifurcation' equations and Galerkin procedure. A buckling mode close to the bifurcation point deformations is proposed. We have obtained reasonable buckling critical values and offered a basis for scientific design.
