The development length of a deformed reinforcement bar can be expressed as $$\left( {1/k} \right)\left( {\phi {\sigma _s}/{\tau _{bd}}} \right).$$

From the $$IS:$$ $$456$$-$$2000,$$ the value of $$k$$ can be calculated as _________________.

Consider the singly reinforced beam shown in the figure below:

At cross-section $$XX,$$ which of the following statements is TRUE at the limit state?

Consider the singly reinforced beam section given below (left figure). The stress block parameters for the cross-section from $$IS:$$ $$456$$ - $$2000$$ are also given below (right figure). The moment of resistance for the given section by the limit state method is ______ $$kN$$-$$m.$$

Workability of concrete can be measured using slump, compaction factor and Vee bee time. Consider the following statements for workability of concrete:

(i) As the slump increases, the Vebe time increases

(ii) As the slum increases, the compaction factor increases

Which of the following is TRUE?
