The maximum ratio of span to depth of a cantilever slab, is
Answer & Solution
Correct Answer:
Option
B
In RCC design, the span to depth ratio is used to control deflection in structural members.
For a cantilever slab, the structure is more prone to deflection because one end is fixed and the other is free.
According to standard guidelines (such as IS 456), the maximum span to effective depth ratio for a cantilever is generally taken as 10.
This limit ensures that the slab remains safe and serviceable without excessive bending or deflection.
Higher ratios like 12 or 16 would lead to excessive deflection, making the structure unsafe.
Therefore, the correct maximum ratio is 10.
