RCC structures such as beams are to be designed by the working stress method. Which of the following expressions is used to check the effective depth (d) of the section?
Where M- service load moment; b- width or breadth of the section; Q- design constant
1
\(d=\sqrt{\frac{Q b}{M}}\)
2
\(d=\sqrt{\frac{M b}{Q}}\)
3
\(d=\sqrt{\frac{Q M}{b}} \)
4
\(d=\sqrt{\frac{M}{Q b}} \)
