Correct Answer - Option 4 : 2.0
Concept:
Slabs:
Slabs are considered as plane element or plate elements which are classified based on aspect ratio.
Aspect ratio:
It is defined as ratio between longer span (Ly) of the slab to shorter span (Lx) of the slab.
\({\rm{Aspect\;ratio}} = \frac{{{{\rm{L}}_{\rm{y}}}}}{{{{\rm{L}}_{\rm{x}}}}}\)
Types of slab based on aspect ratio
1) One way slab:
Slab spanning in one direction
\( \frac{{{{\rm{L}}_{\rm{y}}}}}{{{{\rm{L}}_{\rm{x}}}}}>2\)
2) Two way slab:
Slab spanning in both the direction
\( \frac{{{{\rm{L}}_{\rm{y}}}}}{{{{\rm{L}}_{\rm{x}}}}}<2\)
Explanation:
The ratio of the long to short dimension of the slab is greater than X
By comparing to Aspect ratio of one way slab
i.e \( \frac{{{{\rm{L}}_{\rm{y}}}}}{{{{\rm{L}}_{\rm{x}}}}}>2\)
We get X = 2
