A W24 x 76 of A992 steel is used as a simply supported beam with a span length of 48 feet. The only load in addition to the beam weight is a uniform live load. If lateral support is provided at 12-foot intervals, what is the maximum service live load, in kipsft, that can be supported? Use LRFD.

A W310 x97 steel wide-flange section Supports a uniformly distributed line load on a simple span of 7 m. Assume A36 steel. Calculate the allowable load (kN/m). Neglect the weight of the beam.

A simply supported steel joist of 4 m effective span is laterally supported throughout. It carries a total UDL of 40 kN (inclusive of self weight). Design an appropriate section using steel of grade Fe410. The following two beam sections are available ISMB 150 @ 146 N/m ISMB 175 @ 191 N/m b₁ = tf = 8.6 mm t = 5.5 mm bf = 80 mm = 7.6 mm tf t = 4.8 mm 1₂=726.4 x 104 mmª = 96.9 x 103 mm³ 22 Z₂ R₁ Zp = 9 mm = 110.5 x 103 mm³ = 90 mm = 1272 × 104 mm² Izz Z = 145.4 x 10³ mm³ = 10 mm R₁ Z₁ = 166.1 x 10³ mm³

USE NSCP 2010 A rectangular beam reinforced for both tension and compression barshas an area of 1450 mm² for compression bars and 4350 mm² fortension bars. The tension bars and compression bars are placed at a distance of 600 mm and 62.5 mm respectively from the top of thebeam. The beam width 300 mm, fc’ = 21 MPa, fy = 415 MPa andtension steel covering is 60 mm.If it is 8 m-simply-supported beam that carries three concentratedservice live loads P applied at three quarter points of the beam (exceptat the supports), neglecting the self weight of the beam, determine themaximum value of service load P in kiloNewtons.

The given girder has beams framing into it at the ends and at every L/3 point. The beam carries a service live load of 20 kips as shown and superimposed uniformly distributed service dead load of 10 kip/ft. Select the lightest A992 W-section that can carry the load. Do not check for deflection. P, = 20 kips LL PLL W. = 10 kip/ft DL = 20 ft WDL L/3 BEAMS FRAMING INTO GIRDER L

The beam shown in the figure is a two-span beam with a pin (hinge) in the center of the left span, making the beam statically determinate. There is continuous lateral support. The concentrated loads are service live loads. Determine whether a W12 × 79 of A992 steel is adequate. A 4.2 m 45 kN + 8.4 m 4.2 m B 27 kN hinge 4.2 m + 8.4 m 4.2 m 27 kN +" 4.2 m 8.4 m 4.2 m D

A W36x210 can be used for Transfer Girder ‘A’ as shown in the elevation next page.Assume the LRFD loads on the ‘Transfer Girder’ are as follows:Pu= 200 kips from the column above. Assume also that the loads from self-weight of thewu = 2.0 kip/ft (girder self weight and beams framing into this transfer girder are equivalentto a uniformly distributed load). These loads are shown in the last figure.a) Check whether the W36x210 ‘Transfer Girder’ is adequate for bending and shear.Assume the unbraced length Lb =20 ft.b) Suppose that service loads, w and P, are both 50% dead load and 50% live load. Does theW36x210 satisfy a service live load deflection limit of L/480?

The steelwork framing plan for a floor system shows decks as D1-D12, beams and girders as M1- M20 and columns as C1-C9. The unit load on the system is 75-psf dead and 45-psf live.

An A36 W14X605 simply supported steel beam with span “L” carries a concentrated service liveload “PLL” at midspan. The beam is laterally supported at supports and its midspan. Consider its beam selfweight to be its service deadload, “w” (use ASEP steel manual for selfweight, w and other section properties).
