6. 3 Behaviour of steel beams Laterally stable steel beams can fail only by (a) Flexure (b) Shear or (c) Bearing, assuming the local buckling of slender components does not occur. These three conditions are the criteria for limit state design of steel beams. Steel beams would also on and this is classified as a limit state of serviceability.

For safety, the applied loads are in creased by load factors dictated by appropriate codes. This design is based on the yield property of the steel. Plastic Design of Plastic Design of Steel Floor Beams, Engineering Journal, From the foregoing, it is evident that plastic design in general. Plastic design is a method by which structural elements are selected considering the systems overall ultimate capacity. For safety, the applied loads are increased by load factors dictated by appropriate codes. This design is based on the yield property of the steel. Generally in steelconcrete composite beams, steel beams are integrally The design of the connectors has to be adequate to sustain the shear stress. In CE 470: Design of Steel Structures A. 2 Flexural Deflection of Beams Serviceability Steel beams are designed for the factored design loads. , the factored moment strength (bMn) should be greater than the moment (Mu) caused by the factored loads. check that the beam will support more shear load than is applied. Example# 1 Select the lightest Wbeam that will support a uniformly distributed load of 3 kipft. on a simplysupported span of 20 ft. The beam is rolled highstrength, lowalloy steel (HSLA). Step 1 We know the loading and length; the steel has a yield strength! SUMMARY AND STATUS OF PLASTIC DESIGN OF STEEL MULTISTORY FRAMES by George C.
