Compression vs Compressive Strength

 · If so your E = 4,071 ksi. So with that concrete your Δ would equal your PL/AE based on the E = 4,071 ksi. If you had 3,000 psi specified concrete then E = 57,000(sqrt(3000)) and so on. With weaker concrete (strength-wise) you would have smaller values of E and more deflection under load. The value of E for steel is 29,000 ksi.
