1. The problem statement, all variables and given/known data 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?
