Elastic buckling of a triangular frame subject to in-plane tension

Krzysztof Magnucki, Szymon Milecki
The paper is devoted to elastic buckling of a symmetrical triangular frame under tensile in-plane load. Three mathematical models of the triangular frame are formulated. The first model deals with the pre-buckling state, the second one with the in-plane buckling state, and the third one with the lateral buckling state of the frame. The FEM-numerical model of the frame is formulated and the critical loads are calculated. The comparison of the results obtained in the analytical and numerical-FEM analysis is presented in tables and graphs in figures.
