摘要：
The present study presents a new FEM element for buckling analysis of open section members of mono-symmetry such as T and H-sections and its application to structures. The element is composed, fundamentally, of parallel three beams together with four struts normal to the three elements, enabling a consideration of lateral-torsional buckling. The present study first investigates the capability to analyze buckling strength of beams of T-sections and H-sections, followed by buckling analysis to simple lattice frames. Through the analyses, the effectiveness of the proposed element for buckling analysis is confirmed. © 2024 Architectural Institute of Japan. All rights reserved.
