Un anillo circular delgado de sección rectangular está expuesto a una presión externa. Determine the critical load and corresponding load factor for in-plane buckling.
Un pilar se compone de una sección de hormigón (rectángulo 100/200) y una sección de acero (perfil I 200). It is subjected to pressure force. 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.
Consider an ASTM A992 W 18×50 beam forspan and uniform dead and live loads as shown in Figure 1. La barra está limitada a un canto nominal máximo de 18 pulgadas. 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.
