of 400 mm x 400 mm. it is reinforced by four steel bars each 20 mm
in diameter and carries a load of 1000 kN. Young’s modulus for
steel is 200,000 N/mm2 and for concrete is 15,000 N/mm2. Determine
the deformation in mm?

Answer #1

Given : RCC column cross section =400mm×400 mm

Diameter of steel bar = 20mm

Ec = Young's modulus of concrete

Es =Young's modulus of steel

L = 5 m = 5000 mm

Load = 1000 kN

A column is made of concrete and reinforced with a W-section
steel with an area of 2000 mm2. The dimension of the column is
300mm x 350mm. The column is subjected to an axial load of 100 kN.
What will be the deformed length of the column? Use Es =
200 GPa and Ec = 25 GPa.

A short reinforced concrete column is subjected to a 700 kips
axial compressive load. The modulus of elasticity of plain concrete
