hi
I model rc  building 15 storys ,seismic zone 2,
the strengt of concrete is 25 mpa ,what is the value of the elastic modulus of concrete

RE: lastic modulus of concrete

elastic modulus is a function of the Strength of concrete. It is 57000 * sqrt (fc') in the US units. I am not sure what the metric equivalent is. You should be able to find in ACI 318M

thank you slickdeals for the reply
they told me to use the elastic modulus of concrete short term , the value of E is greater about 1.5 time than E from the equation 57000 * sqrt (fc')
is that correct
