Alcove Realty Interview Questions, Process, and Tips

Anchorage length is the length of the embedded portion of a reinforcement bar, while development length is the length required for full bond strength.

• Anchorage length is determined by the type of structure and the forces it will experience.

• Development length is calculated based on the diameter of the reinforcement bar and the strength of the concrete.

• Anchorage length is typically longer than development length to ensur...read more

Maximum and minimum reinforcement of column

• The maximum reinforcement in a column is typically limited to 4% of the cross-sectional area of the column

• The minimum reinforcement in a column is usually around 0.8% to 1.0% of the cross-sectional area

• Reinforcement in columns is provided to resist bending and shear forces

Ld is the formula for calculating the development length of reinforcement bars in concrete structures.

• Ld = 1.3 * φ * db * fy / σs

• Ld = development length

• φ = reduction factor for tension bars

• db = diameter of the bar

• fy = yield strength of the bar

• σs = permissible stress in the steel

The formula for coding North or East is based on the concept of coordinates and cardinal directions.

• The formula for coding North is +1 in latitude

• The formula for coding East is +1 in longitude

• Coordinates are typically represented using latitude and longitude values

• For example, if the current coordinates are (40.7128° N, 74.0060° W), the coded North coordinates would be (41.7128° N, 74.0060° W)

• Similarly, the coded East

Approximately 10 kg of binding wire is required to bind 1MT of steel bars ranging from 20 mm to 32 mm in diameter.

• Approximately 10 kg of binding wire is needed for 1MT of steel bars with diameters between 20 mm to 32 mm.

• The amount of binding wire required may vary slightly based on the specific dimensions and spacing of the bars.

• It is important to ensure proper binding to maintain structural integrity and safety.

Shuttering oil is used to coat formwork before pouring concrete to prevent it from sticking to the formwork.

• Shuttering oil is applied to formwork to create a barrier between the formwork and the concrete.

• It helps in easy removal of formwork after the concrete has set.

• Proper coverage of shuttering oil ensures smooth and clean concrete surfaces.

• Common types of shuttering oils include mineral oil-based, vegetable oil-base...read more
