Question

select the lightest W shape to support a uniformly distributed load of 2.2 kips/ft. of a simple span of 20 feet.

Answer #1

Select the lightest available W12 shape (A992) to support a
factored axial load of 650 kips and a factored uniform transverse
load of 1.0 kip/ft. Bending takes place about the strong axis only.
The member length is 20 ft. and K = 1.0 typically. Sidesway is
prevented.

Select the lightest section to support a axial load (DL=500 kips y
LL= 300 kips). The element is 30 ft length and braced in the y
direction at 14 ft from the column base. The end support conditions
are (fixed/pinned). Justify the material’s selection (Verify
slenderness and local buckling)

A simply supported beam spans 30 ft. and carries a uniformly
distributed dead load of 3.5 kip/ft,excluding the beam self-weight.
Also, in addition, a concentrated dead load of 15 kips and a
concentrated live load of 25kips, both act at the center of a 30 ft
span.Select the lightest-weight W-Shape to carry the load(A992
steel). Use LRFD method.

Select a lightest W-Shape section with an unbraced length of 10
ft that can carry a maximum moment of 168 ft-kips. Neglect the
moment gradient (Cb=1)using AISC Steel Manual
.

A simply supported beam spans 20 ft. and carries a uniformly
distributed load of 1 kip/ft,including the beam self-weight, and a
live load of 2.5kip/ft. Determine the minimum required plastic
section modulus and select the lightest-weight W-Shape to carry the
moment (A992 Steel). Use LRFD method.

Select the lighest W section to carry a uniformly distributed
load of 0.2 kip/ft superimposed (i.e. in addition to the beam
weight) and 0.8 kip/ft live load. The simly supported span is 20'
and the compression flange is fully supported against lateral
movement. Use LRFD and select for the following steels: A36, A992,
and A572 Gr. 65

A simply supported beam spans 20 ft and carries a uniformly
distributed dead load of 0.8 kips/ft including the beam self-weight
and a live load of 2.3 kips/ft. Determine the required plastic
section modulus and select the lightest weight Wshape to carry the
moment. Consider only the limit state of yielding (Zone 1) and use
A992 steel. Design by (a) LRFD and (b) ASD.

W 18X60 steel beam has 10 ft simple span. The beam carries a
uniform load of 4 kips/ft including its weight. The allowable
deflection is 1/360 of the span length. Determine whether the beam
is satisfactory for deflection.

Select the lightest, rectangular Douglas fir section for the
cantilever beam of 10- ft span that will carry a uniform load of
250 lb/ft

The beam is subjected to a uniformly distributed load
w= 12 kN/m. The beam is a two-span continuous beam. The
length of each span is L = 2 m. The beam is made of steel.
Young's modulus (E) of steel is 200 GPa. The value of the moment of
inertia is 21 * 106 mm4. Use the force method
given in Week 6. Determine the reaction at the middle support
B.
Select one:
a. 6.00 kN
b. 18.00 kN
