Abstract: This paper presents a detailed treatment of the formulation for buckling and dynamic instability analysis of tapered thin‐walled beams of generic open section. The theory developed is limited to small strains, moderate ...

Abstract: Buckling loads and natural frequencies and the corresponding modal shapes and forms for thin‐walled tapered beams of open sections are examined using the finite‐element method. A tapered thin‐walled bar finite element with ...

Abstract: A finite element nonlinear formulation for the stability analysis of a conical concrete shell roof for a cathedral in India is presented. The degenerated shell elements are used to idealize the shell and the buckling load ...
