As shown, a pipe serves as a short column. The 4 - inch diameter steel pipe has 6 in x 6 in in steel plates welded to its ends.The top column plate carries a 5-1/8" wide wood beam that exerts an axial load on the column of 11,800 lbs., including the weight of the beam. The bottom plate bears on a concrete pad. The weight of the column is 53.5 lbs. Compressive stress in the steel must not exceed 20,000...
As shown, two composite columns of steel and concrete are used to support a rigid platform. The columns are cylindrical, with a steel bar encased in concrete. The outer diameter of each column is dc = 24 cm. The steel in the left column has a diameter of dı = 18 cm. A load of P = 52 kN is applied with L1 = 1.5 m and L2 = 2.2 m. The height of the columns is h = 2.6...
A marble column with a cross-sectional area of 26.00 cm2 supports a load of 7.300 × 104 N. (Marble: Y = 6.100 × 1010 Pa; compressive strength = 2.200 × 108 Pa.) (a) What is the stress in the column? Pa (b) What is the strain in the column? (c) If the column is 1.400 m high, how much is its length changed by supporting the load? m
P B A pressurized cylindrical air tank is subjected to a force P at a collar B. The tank has an inner diameter (d = 160 mm) with wall thickness (1 = 6 mm). The gage pressure inside the tank is p = 5 MPa and the applied force is P = 9.5 kN. (a) Determine the maximum tensile stress o [MPa), maximum compressive stress oc [MPa] and maximum shear stress imax [MPa) at point a. (b) Repeat part (a)...
(30points)Atimber H-shaped short column consistsof three 20 X 100mm planks which are fastenedtogetherto form an 100mm wide, 140mm depth cross section as shown inthefigure. If a vertical compressive load P is applied at point C located on the axis of symmetry of the cross section of short column, and pointC is 40mm from point A on the cross section.. Knowingthat the allowable stress(either in tensile or compressive stress)is 2.0Mpa.
Design a square tied column to carry axial service loads of 320
kips dead load and 190 kips live load. There is no identified
applied moment. Assume that the column is short. Use f’c =4000 psi
and fy = 60,000 psi. Also, draw the flexural and shear
reinforcement on a sketch.
Case 3: Design of Short Columns - Small Eccentricity Design a square tied column to carry axial service loads of 320 kips dead load and 190 kips live load....
Find the maximum design axial load strength for the tied column
of cross section shown in Figure 1.1. Check the ties. Assume a
short column. Use f’c = 4000 psi and fy = 60,000 psi for both
longitudinal steel and ties. Also, draw the flexural and shear
reinforcement on a sketch.

1) [Design] A reinforced concrete column is to be sized to carry pure axial compressive load. According to ACI 318, what is the smallest possible cross-sectional area (Ag) that the column can use in design supporting an axial dead load of 200 kips (unfactored) and live load of 400 kips (unfactored). Use fc = 4,000 psi and fy = 60 ksi. Assume pe = 0.08 and ties for transverse reinforcement. Be sure to include the appropriate design factors and use...
A column in the upper story of a building is subjected to a compressive load from the following sources: . dead load = 30.8 kips, . occupancy live load = 1.7 kips, (Assume this is from a live load of less than 100 psf, and it is not a garage or place of public assembly.) . roof live load = 18.7 kips, and snow load 19.7 kips. If the load and resistance factor design (LRFD) method is used, what is...
