Identify the FALSE statement from the following, pertaining to the design of concrete structures.
-
- The assumption of a linear strain profile in flexure is made use of in working stress design, but not in ultimate limit state design.
- Torsional reinforcement is not required to be provided at the corners of simply supported rectangular slabs, if the corners are free to lift up.
- a rectangular slab, whose length exceeds twice its width, always behaves as a two way slab, regardless of the support conditions
- The ‘load balancing’ concept can be applied to select the appropriate tendon profile in a prepossessed concrete beam subject to a given pattern of loads.
Correct Option: A
In working stress method, concrete is assumed to be elastic and obeys Hook's law. The assumption for linear strain profile in flexure is made use of in limit state design.
