Design a reinforced concrete steel rectangular tie column with
ACI standards, total LL = 14.0625 kips, total DL = 18.95625kips,
cross-section 12in by 12 in, Hight of column 12ft. Show all the
steps and which table used. Assume the information which is not
given with justifications. Show drawing as well. If the high is not
suitable you can change it.
Design a square interior column footing for a 15-in. square tied
interior column that supports a dead load of 160 kips and live load
of 180 kips. The column is reinforced with eight # 8 bars, also,
the base of the footing is 6 ft below the grade line, the soil
weight is 100 lb/ft3, the concrete weight is 150 lb/ft3, f’c =
4,000 psi, fy = 60,000 psi and qa = 4 kip/ft2.
QUESTIONS:
Design a square column footing for a 20-in. square
tied interior column that supports loads of DL (170) k and Live
load LL (210) k. The column is reinforced with eight No 8 bars, the
bottom of the footing is 5 foot below final grade, and the soil
weighs 100 lb. /ft3 the allowable soil pressure is 4 w ksf. The
concrete strength is 4,000 psi and the steel is Grade
60.
Design a square tied column to support an axial dead
load of (W1) k and an axial live load of (W2) k.
Begin using approximately (X) percent longitudinal
steel, a concrete strength of 4,000 psi and Grade 60
steel.
Draw the details of reinforcement and
check all ACI recommendation.
W1 = 220 k
W2 = 165 k
X = 2%
A short reinforced concrete column is subjected to a
1000 kN axial compressive load. The moduli of elasticity of plain
concrete and steel are 25 GPa and 207 GPa, respectively, and the
cross-sectional area of steel is 2% 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
rebars, calculate the following:
a. the modulus of elasticity
of the reinforced concrete
b. the load...
