Tensile Strength of Concrete

Written by Jerry Ratzlaff on . Posted in Civil Engineering

Tensile strength of concrete, abbreviated as \(f_t\), is valid for normal weight, normal density concrete.


Tensile Strencth of concrete formula

\(\large{ f_t =  7.5 \; \sqrt{ f_{c}{'}  }   }\)  (Emglish units)
\(\large{ f_t =  0.7 \; \sqrt{ f_{c}{'}  }   }\)  (Metric units)


 Units English Metric
\(\large{ f_t }\) = tensile strength of concrete  \(\large{\frac{lbf}{in^2}}\)  \(\large{MPa}\)
\(\large{ f_{c}{'} }\)  = concrete specified cylinder 28-day compression strength \(\large{\frac{lbf}{in^2}}\) \(\large{MPa}\)
