2.8) A square reinforced concrete pier 300 mm x 300 mm in cross-section and 2.5 m high has 8 steel square reinforcing bars, each 20 mm x 20 mm, placed symmetrically about the vertical axis of the column, and running the full vertical height. The steel is bonded to the concrete such that the axial displacements of both materials remain equal to each other. If concrete has a Young's modulus 1/12th that of steel, determine the stresses in the steel and in the concrete due to a downward axial load of 400 KN. 2.8) A square reinforced concrete pier 300 mm x 300 mm in cross-section and 2.5 m high has 8 steel square reinforcing bars, each 20 mm x 20 mm, placed symmetrically about the vertical axis of the column, and running the full vertical height.

Answer rating: 100% (QA)

To determine the stresses in the steel and the concrete we first need to calculate the axial forces ... View the full answer
