How much force does it require to tear apart steel, iron ...

In the link we can see that iron has a tensile strength of 350 MPa, which means that it takes a force of 350 million Newton to pull apart a one square meter thick column of iron. Concrete is listed at 2-5 MPa and steel between 400 and 2700 MPa. It should be noted that while concrete doesn't resist tension well, it does resist compression well.
