Question

A short, square tied column has a minimum area of reinforcing
steel of 3.24 in^{2} and a gross area of 18 in^{2}.
The compressive strength of the concrete is 4000 lbf/in^{2}
and the yield strength of the steel is 60,000 lbf/in^{2}.
What is most nearly the design axial compressive load capacity?

A) 130 kips

B) 140 kips

C) 570 kips

D) 400 kips

Answer #1

*ANSWER :*

*THE ANSWER IS SHOWN IN BELOW HAND WRITTEN
NOTES:*

A
500mm width square tied column with reinforcement on four faceshas
a gross steel ratio is 0.02 and the concrete cover from the column
surface to the steel centroid is 100 mm.
what is the nominal axial capacity of the column if subjected
to biaxial bending where ex=ey=250 mm? use fy'=21 Mpa and fy= 415
Mpa, reciprocal load method and interaction diagram below.

Deign a square tied column to support a service axial dead load
P_d of 200 K and a live load P_l of 300 K using concrete f_c^'=4000
psi and bars f_y=60000psi (use steel ratio of about 3% design the
ties and check the ACI code requirements)
ACI-318

A short reinforced concrete column is subjected to a 700 kips
axial compressive load. The modulus of elasticity of plain concrete
and steel are 4,500,000 psi and 29,000,000, respectively, and the
cross-sectional area of steel is 3.0% of that of the reinforced
concrete. Considering the column as a structural member made of a
composite material and subjected to load parallel to the steel
bars. Calculate the modulus of elasticity of the reinforced
concrete, as well as how much load is...

Design a square axially loaded short square tied column for
concentric ultimate axial load Pu = 2600 kN. f’c = 28 MPa and fy =
350 MPa. assume ρ = 0.02.
Draw the section details showing dimensions, cover, rebars,
stirrups (ties), ..etc.

1. (a) Explain the difference between
columns which are short and slender
and those which are braced and
unbraced.
(b) Calculate the ultimate axial load
capacity of a short-braced column
supporting an approximately
symmetrical arrangement of beams
assuming that it is 500 mm square
and is reinforced with eight
20 mm diameter bars. Assume that
fcu = 40 N/mm2, fy = 500 N/mm2 and
the concrete cover is 25 mm. Design
the shear reinforcement for the
column.
2. (a) A...
