  1. A three storey steel column in a building supports roof and floor loads. The story height H is 3m, the cross sectional area of the column is 10000mm2, and the modulus of elasticity of steel is 200 GPa. The load carried by the column of each floor are as follows, P1 = 30kN, P2 = 30 kN, P3 = 25 kN.
  1. What is the strain energy of the ground floor column?
  2. What is the strain energy of the second floor column?
  3. What is the strain energy of the third floor column?

(30 pts) 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....

A 24 in. x 16 in. column on the second floor of a multi-story building is to be designed to carry a live load of 500,000 lb, and a dead load that is 75 % of the live load (includes self weight). The nominal moment is calculated to be 5,769 kip.in. Use the interaction diagrams with γ = 0.8 to design the column reinforcement for a concrete strength of 4000 psi and a steel strength of 60000 psi. Include the...

During construction, field tests were conducted to assess the suitability of the column to withstand a safe buckling load of 2.5 kN assuming a factor of safety 4 using two different hollow columns made up of steel and concrete. Both columns have same cross section but varying length and different support conditions. Steel column of length 3 m having external diameter 40 mm was tested with one end fixed and the other end hinged, when subjected to a compressive stress...
