A strut with a circular cross-section is supported according to four basic cases of Euler buckling and subjected to pressure force. Determine a carga de encurvadura crítica.
Considere o vão da barra ASTM A992 W 18×50 apresentado na Figura 01 e as cargas permanentes e variáveis uniformes. The member is limited to a maximum nominal depth of 18 inches. The live load deflection is limited to L/360. The beam is simply supported and continuously braced. Verify the available flexural strength of the selected beam, based on LRFD and ASD.
A column is composed of a concrete section (rectangle 100/200) and a steel section (profile I 200). Está sujeito a uma força de compressão. Determine the critical load and corresponding load factor. The theoretical solution is based on the buckling of a simple beam. In this case, two regions have to be taken into account due to different moments of inertia and material properties.
Um quarto de barra circular com uma secção retangular é carregado com uma força fora do plano. This force causes a bending moment, torsional moment, and transverse force. While neglecting self-weight, determine the total deflection of the curved beam.
