Question

To learn how to find internal forces for a statically indeterminate axially loaded structure by using deformation compatibility relationships and static equilibrium equations. A reinforced concrete pier supports a 350 kip axial compressive load as shown. The 12-in-diameter concrete pier is reinforced with 6 #8 (i.e., 1-in diameter) steel reinforcing bars (i.e., rebar). The steel and the concrete are assumed to be bonded together (i.e., there is no slip between them upon loading). The modulus of elasticity for the steel rebars is 29,000 ksi and the modulus of elasticity for the concrete is 4,200 ksi.

▾ Part A - Find the axial stress in the concrete when the pier is loaded
A reinforced concrete pier supports a 350 kip axial compressive load as shown. The 12-in-diameter concrete pier is reinforced with 6 # 8 (i.e., 1-in diameter)
steel reinforcing bars (i.e., rebar). The steel and the concrete are assumed to be bonded together (i.e., there is no slip between them upon loading). The
modulus of elasticity for the steel rebars is 29,000 ksi and the modulus of elasticity for the concrete is 4,200 ksi.
