AI Thread Summary
The discussion revolves around calculating key parameters for a concrete column reinforced with steel under a compressive load. Participants emphasize the importance of starting with relevant equations, particularly those related to Young's Modulus, stress, and strain. The calculations needed include the stress taken by the steel, the change in length of the column, and the factor of safety based on the ultimate compressive strength of concrete. There is encouragement for users to share their initial attempts to facilitate guidance. Understanding the relationship between stress, strain, and Young's Modulus is highlighted as crucial for solving the problem.

Homework Statement


a concrete column, 4.5m long, is reinforced with steel bars and carries a compressive load of 58 tonnes. The overall cross-sectional area of the column is 0.1m squared and the steel reinforcement accounts for 5 percent of this area. take young's modulus for steel as 200 GN/m squared, young's modulus for concrete as 20 GN/m squared and ultimate compressive strength
for concrete 50 MPa. calculate,

the stress taken by the steel?

change in length of the column?

the factor of safety based upon the UCS for concrete?

welcome to pf!

hi emma louise! welcome to pf! :wink:

show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:
 
hiii:) i haven't tried anything yet, I am just wondering how to start it?

You start by posting the Relevant Equations. Does Young's Modulus have anything to do with stress and strain?
