Rebar Tension Capacity
Rebar Tension Capacity
The tension a reinforcing layer can carry sets the flexural and tie capacity of reinforced concrete.
The capacity is T = A_s·f_y. where A_s is the steel area and f_y the yield strength.
Inputs
A_s := 1200 mm^2=1.2e-03 m^2
f_y := 500 MPa=500 MPa
Multiply the steel area by its yield strength.
T := A_s·f_y=600000 N
Results
This yield force, paired with the concrete compression block, gives the section’s moment capacity. More or stronger bars raise it.
Assumptions & limitations
- Steel yields (under-reinforced section).
- Full bond to concrete.
- Strength (not service) basis.
