Question

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.

Answer #1

Please give thumbs up

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.

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.

design for flexure a beam 12 ft in length,ot a992 steel, with a
uniformly distributed live load of 1 kip/ft, and a concentrated
dead load of 8.4 kips a distance of 5 ft from one end

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

design a simply supported floor beam of A992 steel to carry a
De0ad load of 0.5k/ft and a Live load of 1.5k/ft over a span 24 ft.
The beam has Full lateral bracing provided. Show All steps.

A simply supported beam is 3 m long. It carries a uniformly
distributed load of 6 kN/m throughout its span and a concentrated
load of 15 kN at a point 2 m from the left support. Assuming that
the beam has a rectangular shape whose width and depth are 150 mm
and 250 mm, respectively. Determine the maximum flexural stress in
MPa developed in the beam.

A 14ft pin-ended column in a braced frame must carry a
compressive dead load of 65 kips and live load of 130 kips, along
with a uniformly distributed transverse dead load of 0.5 kips/ft
and live load of 2.5 kips/ft. Will a W12x58, ASTM A992 member be
adequate if the transverse load is applied to put bending about the
strong-axis? LRFD.

A rectangular RC beam is simply supported over a span of 8m and
carries a dead load of 15kN/m (including self-weight) and an
imposed load of 8kN/m. The beam is 250mm wide and has an effective
depth of 400mm. Grade 30 concrete is to be used.
Determine if the beam should be singly reinforced or
doubly reinforced.

A simply supported beam of 6m length carries a dead load of 10
kn/m and live load of 8 kn/m. It also support a point dead load of
60Kn at the centre. Using the formula calculate the moment
modification factor.

Design an all-bolted double-angle connection for a W18×65 A992
beam to carry a dead load reaction of 15 kips and a live load
reaction of 45 kips. Use 5/16 in. A36 angles and 3/4 in. A325-N
bolts in standard holes. The uncoped beam is connected to the
flange of a W14×109 A992 column. Design by LRFD.
