3000 Psi to Megapascal Conversion - Convert 3000 Psi to

Psi : Psi is the abbreviation of pound per square inch, and is widely used in British and American. 1 psi = 6,894.76 Pascals. Megapascal : The megapascal (symbol:MPa) is a non-SI unit for pressure, and is a x1000000 multiple of the Pascal unit. 1 MPa equals 1,000,000 Pa. It is primarily used for higher range pressure measurement and mainly used to describe the pressure ranges and ratings of

Allowable Stress Design of Concrete Masonry - 2005

The modulus of elasticity, Es, of mild steel reinforcement is assumed to be 29,000,000 psi (200 GPa). The code-prescribed allowable steel stresses are as follows (ref. 1): For Grade 60 reinforcement in tension: Fs = 24,000 psi (165.5 MPa) For Grade 40 and 50 reinforcement in tension: Fs = 20,000 psi (137.9 MPa)

EVALUATING THE COMPRESSIVE STRENGTH OF CONCRETE MASONRY

As an example, using either Table 1 or Table 2 for concrete masonry units with a compressive strength of 2,600 psi (17.93 MPa), the maximum f’ m used in design would be 2,250 psi (15.51 MPa) if Type M or S mortar were used. Note that per footnote A of Table 1 and Table 2, compressive strength of masonry values must be multiplied by 85% when
