Question
Transcribed Image Text:a.) A 3-m height concrete column is reinforced with 4 steel reinforcement bars, each bar with a 25
mm diameter. Determine the normal stresses in the concrete and steel when an axial centric force
of P = 660 kN is applied to the column. Determine also the shortening of the column.
The modulus of elasticity of the concrete and steel has values of Ec = 26 GPa and Es=200 GPa
The cross section of the column is shown in the figure.
b.) If the steel reinforcement bars are to resist at least 1/3 of the applied load, calculate the minimum
amount of area of steel reinforcement bars required. What is the minimum of number of 25 mm
