Considérons la travée de barre ASTM A992 W 18×50 ainsi que les poids propre et les charges d'exploitation représentés sur la Figure 1. 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.
Un poteau est composé d'une section en béton (rectangle 100/200) et d'une section en acier (profilé 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.
Une poutre quart de cercle de section rectangulaire est chargée par une force hors plan. This force causes a bending moment, torsional moment, and transverse force. While neglecting self-weight, determine the total deflection of the curved beam.
