$${\rm II}.\,\,\,\,\,\,\,\,\,\,\,\,$$ The maximum compressive strain in concrete in axial compression is taken as $$0.002$$ Keeping the provisions of $$IS$$ $$456$$-$$2000$$ on limit state design in mind, which of the following is true?

Statement $${\rm I}$$ is true but $${\rm II}$$ is false

Statement $${\rm I}$$ is false but $${\rm II}$$ is true

Both statements $${\rm I}$$ and $${\rm II}$$ are true

Both statements $${\rm I}$$ and $${\rm II}$$ are false

As per provision of $$IS$$ $$456$$-$$2000$$, in the limit state method for design of beams, the limiting value of the depth of neutral axis in a reinforced concrete beam of effective depth $$'d'$$ is given as

$$0.53$$ $$d$$

$$0.48$$ $$d$$

$$0.46$$ $$d$$

any of the above depending on the different grades of steel.

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 prestressed concrete beam subjected to a given pattern of loads.

GATE CE 2000

MCQ (Single Correct Answer)

-0.6

The following two statements are made with reference to a simply supported under - reinforced $$RCC$$ beam:

$${\rm I}.\,\,\,\,\,\,\,\,\,\,\,\,$$ Failure takes place by crushing of concrete before the steel has yielded.
$${\rm II}.\,\,\,\,\,\,\,\,\,\,$$ The neutral axis moves up as the load is increased.

With reference to the above statements, which of the following applies?

Both the statements are false

$${\rm I}$$ is true but $${\rm I}$$$${\rm I}$$ is false

Both the statements are true

$${\rm I}$$ is false but $${\rm I}$$$${\rm I}$$ is true
