Consider a W30x99 beam (Fy = 60 ksi) that is simply supported,
30 ft. long, and subjected to a point load
at the midspan. The point service load consists of 60% live load
and 40% dead load. Lateral supports exist
at the ends only. Design code to comply with: 2016 AISC LRFD.
(a) Determine the maximum point service load P for strong-axis
bending assuming Cb = 1.0.
(b) Redetermine the maximum point service load P for strong-axis
bending considering proper Cb value.

STEEL STRUCTURES
A 20ft long simply supported beam is made of W21X55 with
fy=50ksi. The service distributed loads on the beam are DL=2k/ft
(including self weight), LL=4 k/ft. Show if the beam is adequate
for shear.

You are analyzing a 40 FT long simply supported beam (b = 10 IN,
d = 21.5 IN, h = 24 IN) in an existing building. The dead load on
this beam is 1.2 KLF and you are tasked with deciding whether a
load of 2 KLF of live load can be applied in addition. Based on the
original plans, you think that the compressive strength of the
concrete f’c = 3000 PSI and the yield strength of the rebar...

A
simply supported 7 ft long solid wooden beam is designed to carry a
concentrated load P = 600 lbf in the center. The distance between
supports is 72 inches. The cross sectional area is 2” (inches) wide
and 6” (inches) high. Determine the moment of mass of the beam
(lbm), inertia (in4) and deflection (in). This wood has the
following material properties: Modulus of elasticity = 2.5 x 106
psi and Density = 40 lbm/ft3.

A simply supported beam with a span of 26 FT is used to carry a
service dead load (including self-weight) of 1.65 KLF and a service
live load of 3.3 KLF and is reinforced with 4-#9 bars. The beam has
a width b of 14 IN, an effective depth of 24.5 IN., and a height of
27 IN. The material strengths are f’c = 4000 PSI and fy = 60 KSI.

(1) A simply supported steel beam is 30' long and subjected to a
uniform distributed 1.3 kips per foot. What is the minimum required
section modulus for this beam if we do not want its maximum stress
to exceed 50 ksi?
(2) What is the minimum inertia of the beam in the previous
question if we do not want it to deflect more than 1/2" ?

A 35 ft simply supported beam is loaded with concentrated loads
15 ft in from each support. On one end, the dead load is 8.0 kips
and the live load is 18.0 kips. At the other end, the dead load is
4.0 kips and the live load is 9.0 kips. Include the self-weight of
the beam in the design. Lateral supports are provided at the
supports and the load points. Determine the least-weight W-shape to
carry the load. Use A992...
