If $$A\_c, A\_w$$ and A are areas of concrete, longitudinal steel and section of a R.C.C. column and m and $$\sigma\_c$$ are the modular ratio and maximum stress in the configuration of concrete, the strength of column is?

GitBook practice — Set 8 (Poush, 2081)

A$$\sigma\_c A\_c + m \sigma\_c A\_w$$

B$$\sigma\_c (A - A\_w) + m \sigma\_c A\_w$$

C$$\sigma\_c \[A + (m - 1)A\_{sc}]$$

DAll the above
