So if the beam is holding a load over a span, then the concrete on the bottom of the beam, which is experiencing tensil force, is doing little? I mean, I assume concrete has poor tensile strength.

- euroclydon 9y agoThanks. That's reassuring; does not catastrophically fail.
- ghaff 9y agoConcrete's tensile strength is about 10% of its compressive strength. So, yes, unreinforced concrete is quite weak in tension.
- bluthru 9y agoThat's where the rebar is located.
