## Marks 1

The development length of a deformed reinforcement bar can be expressed as $$\left( {1/k} \right)\left( {\phi {\sigma _s}/{\tau _{bd}}} \right).$$ Fr...
As per $$IS$$ $$456:2000$$ for $$M20$$ grade concrete and plain barsin tension the design bond stress $${\tau _{bd}} = 1.2\,\,MPa.$$ Further, $$IS$$ \$...
In the design of a reinforced concrete bean the requirement for bond is not getting satisfied. The economical option to satisfy the requirement for bo...
As per $$IS:$$ $$456$$-$$2000,$$ consider the following statements: $$1.$$ The modular ratio considered in the working stress method depends on the ty...
If $$\phi \, = \,$$ nominal diameter of reinforcing bar, $${f_s}\, =$$ compressive stress in the bar and $${f_{bd}}\, =$$ design bond stress of conc...

## Marks 2

Consider a bar of diameter $$'D'$$ embedded in a large concrete block as shown in the adjoining figure, with a pull out force $$P$$ being applied. Let...
Consider the following two statements related to reinforced concrete design, and identify whether they are TRUE/FALSE: $${\rm I}.$$ Curtailment of ba...

## Marks 5

A continuous beam $$250\,mm \times 450\,mm$$ carries $$6$$ numbers of $$12$$ $$mm$$ diameter longitudinal bars as shown. The factored shear force at t...
