- SITUATION 2 A four-meter intermediate floor beam is made of ASTM A992 steel (Fy = 350 MPa; F, = 450 MPa) rolled into W14x82 section. The beam is laterally braced at its supports and at its midspan only. The beam is to be subjected to a uniform gravity loads (dead and live) such that the ratio of total uniform service dead load to total uniform service live load is 3.00. The beam is also subjected to a concentrated dead load of 15 kN and concentrated live load of 25 kN each at its third points. The maximum service live load deflection of the beam must not exceed 25 mm. ASD specifications were used for the design of the beam. (a) Assess the beam section if local buckling will significantly affect its flexural strength. Classify the beam section as compact, non-compact, or slender. (b) Determine the design flexural capacity of the beam considering either yielding or flange buckling (depending if the section is compact, non-compact, or slender). (c) Determine the design flexural capacity…Design a grade B Cypress wood beam, the cantilever beam has a span of 8 ft, has a uniformly distributed load of 150 lb/ft and an applied point load at the end of the cantilever of 1500 lb. The deflection is limited by L/360. The loads include the self weight of the beamView Policies Current Attempt in Progress AW18 x 40 standard steel shape is used to support the loads shown on the beam. Assume P-20 kips, w-2.4 kips/ft.
