碩士 === 國立臺灣海洋大學 === 河海工程學系 === 98 === Abstract Arched structure common in mechanical, aerospace and civil engineering, especially in civil engineering applies to lack, such as dam, bridge, arch-shaped roof, and so the use of the unique characteristics of arch structure. However, often arched structure occurred during the construction phase of unstable behavior, a conservative estimate of the buckling load the structure will help prevent the sudden collapse occurs. This article is mainly for the dome structure to withstand radial and transverse uniform load uniform load, according to non-linear response, combined with Newton La Fusen numerical methods for nonlinear structural analysis and estimating the critical balance plane, and according to Results of perturbation force after buckling and displacement relationship. Analysis using SAP2000 software to help and to verify the accuracy of the research methods.
