Question: the concrete e 29 gpa pier shown in the...

Question details

The concrete [E = 29 GPa] pier shown in the figure is reinforced by four steel [E-200 GPa] reinforcing rods, each having a diameter of 24 mm. Assume P = 675 kN, L -1.55 m, and a245 mm. If the pier is subjected to an axial load of 675 kN, determine (a) the normal stress (positive if tensile and negative if compressive) in the concrete and in the steel reinforcing rods. (b) the deflection of the upper end of the pier (positive if downward and negative if upward)
