Jio Fttx Construction Engineer Interview Questions and Answers

Q1. Development length of steel in beam
Ans. 
Development length of steel in beam is the length of embedded reinforcement required to transfer the stresses to the concrete.
• Development length is influenced by factors like concrete strength, steel strength, bond strength, and diameter of the bar.

• It is calculated using empirical formulas provided by codes like ACI or IS.

• For example, ACI 318 provides formulas for calculating development length based on various paramet

Q1. Dia of yhe steel
Ans. 
The diameter of the steel refers to the measurement of the cross-sectional size of the steel material.
• The diameter of the steel is an important parameter in construction engineering as it determines the strength and load-bearing capacity of the material.

• It is commonly used to specify the size of reinforcing bars (rebars) used in concrete structures.

• For example, a #4 rebar has a diameter of 1/2 inch, while a #8 rebar ha...read more
