The analysis of slab spanning in one direction is done by assuming it to be a beam of
Show Hint
For slab design,
\[
\boxed{
\text{One-way slab}
\rightarrow
\text{Beam of unit width }(1\text{ m})
}
\]
This simplifies the calculation of bending moments and reinforcement.

The Correct Option is B
Solution and Explanation
Concept:
A one-way slab carries load primarily in one direction.
For analysis and design, the slab is idealized as a beam of unit width spanning between the supports.
The bending moment and shear force are calculated for this unit-width strip.
Step 1: Understand one-way slab action. In a one-way slab, \[ \boxed{ \frac{L_y}{L_x}\ge2 } \] where \[ L_x=\text{Shorter span}, \] \[ L_y=\text{Longer span}. \] The slab bends mainly along the shorter span.
Step 2: State the design assumption. For analysis, the slab is considered as \[ \boxed{\text{a beam of unit width }(1\text{ m}).} \] Therefore, the correct option is \[ \boxed{(B)\;1\text{ m width}.} \]
