A 40 ft simple span beam is loaded with a uniform dead load of 2.4 kips/ft plus the beam self-weight and a uniform live load of 3.3 kips/ft. The lateral supports are located at the supports and at the midpoint of the span. Determine the leastweight W-shape to carry the load. Use A992 steel and Cb= 1.0. Design by (a) LRFD and (b) ASD.

Q1. The column carries 60 kips dead load and 40 kips live
load, its length is 20 ft, and the steel is A992. Assume the member
as pinned at the top and bottom.
(a) Compute Pa;
(b) Determine the effective length (KL);
(c) Use ASD method to select the lightest W section;
(d) Check the local buckling slenderness limits of the
selected section.

Design a rectangular reinforced concrete beam for a simple span
of 35 ft. Uniform service loads are 1.0 kip/ft dead load (excluding
the self-weight of the beam) and 1.2 kips/ft live load. Use
f′c=4,000 psi and fy=60,000 psi. Sketch your design.

Design a rectangular reinforced concrete beam for a simple span
of 32 ft. Uniform service loads are 1.5 kips/ft dead load and 2.0
kips/ft live load. Assuming that the total depth h is not to exceed
32 in. and that there is no limitation on the width b. Use f′c =
3000 psi and fy = 60,000 psi. Sketch your design

The service load bending moments on a beam are 128 kip-ft for
dead load and 107 kip-ft for live load. The beam is 12 in. wide,
f’c is 3000 psi and fy is 60 ksi. Determine Mu, Mt, p, R, the depth
of the beam and the As of tensile reinforcing required. How many
no. 8 bars or No. 10 bars would have the required As?

A 16-ft long pin-pin column has to support a dead load of 100
kips and a live load of 280 kips. Using column selection tables
from the Steel Manual select columns for the given shapes. All
selections should be structurally safe and least weight.
50-ksi W-section (W10, 12, 14 only)
35-ksi pipe (standard, x-strong, xx-strong)
46-ksi rectangular HSS
46-ksi square HSS
42-ksi round HSS

Select a 12 ft cantilever beam with p = 0.012, to
support a dead load of 2k/f (including self weight) and Live load
of 3 k/ft. fy= 60000 psi, fc'= 3500 psi (hint your answer should be
Width = XXXX, Effective depth= XXXXX, Area of reinforcement =
XXXXX)

A Simply supported rectangular, tension-reinforced beam is to be
designed for dead load of 0.75 k/ft plus self weight and service
live load of 2.0 k/ft, with a 30 -ft simple span. Material strength
will be fy = 60 ksi and fc = 5 ksi for steel and normal weight
concrete respectively.
Start the design of the beam dimensions using the rules of
thumbs in class. The total beam depth, h, must not exceed twice the
width.
