Q1. Minimum cement contains in RCC structure
Ans. 
The minimum cement content in RCC structure is typically around 300 kg/m3.
• Minimum cement content is usually specified by structural engineers based on design requirements.

• Higher cement content may be required for structures in aggressive environments or with special design considerations.

• The minimum cement content is important for achieving the desired strength and durability of the concrete mix.

Q2. In slump cone test what is the shape of slump
Ans. 
The shape of slump in a slump cone test is typically conical.
• The shape of slump is conical, with the top being wider than the base.

• The height of the slump is measured to determine the workability of the concrete.

• Different types of slumps (true slump, shear slump, collapse slump) indicate different levels of workability.

• Example: A true slump has a smooth, symmetrical shape with a slight collapse at the center.

Q1. Lapping zone of column
Ans. 
Lapping zone of column is where two reinforcement bars overlap to ensure continuity of load transfer.
• Lapping zone should be at least 50 times the diameter of the smaller bar away from the face of the support.

• Proper lapping length is crucial for structural integrity and load distribution.

• Lapping should be staggered in multiple layers for better strength.

• Ensure proper cover and clear spacing around the lapping zone to pr

Q1. What is PT slab about pt slab
Ans. 
PT slab refers to a post-tensioned slab, which is a type of reinforced concrete slab that uses high-strength steel tendons to provide additional strength and reduce cracking.
• PT slab is a structural system commonly used in buildings and bridges.

• It involves the use of steel tendons that are tensioned after the concrete has hardened.

• The tendons are typically placed in a grid pattern and anchored at the ends of the slab.

Q2. What is steel density
Ans. 
Steel density is the measure of how much mass is contained in a given volume of steel.
• Steel density is typically measured in kilograms per cubic meter (kg/m³).

• The density of steel can vary depending on its composition and specific type.

• For example, the density of carbon steel is around 7850 kg/m³.

• Stainless steel, on the other hand, has a density of about 8000 kg/m³.

• Density is an important property to consider in struct

Q1. Whats the difference between omrf and smrf
Ans. 
OMRF and SMRF are two different seismic force-resisting systems used in building construction.
• OMRF stands for Ordinary Moment Resisting Frame and is used for low to moderate seismic zones.

• SMRF stands for Special Moment Resisting Frame and is used for high seismic zones.

• OMRF is designed to resist lateral forces through flexural strength of beams and columns.

• SMRF is designed to resist lateral forces through a combination...read more

Q2. Where and why we release moments in a truss
Ans. 
Moments are released in trusses at points where the truss is supported by a fixed joint or a roller joint.
• Moments are released to prevent the truss from rotating at the support point.

• Fixed joints do not allow any rotation, so moments are released at those points.

• Roller joints allow rotation in one direction, so moments are released in the perpendicular direction.

• Releasing moments also helps to distribute the load evenl...read more

Q1. Why use reinforcement for structure
Ans. 
Reinforcement is used in structures to increase strength, durability, and resistance to various forces.
• Reinforcement helps to distribute loads more evenly throughout the structure.

• It increases the tensile strength of the structure, making it more resistant to bending and cracking.

• Reinforcement can also improve the overall durability and longevity of the structure.

• Common types of reinforcement include steel bars, mesh, ...read more

Add your answer

Q1. Explain anchorage of reinforcing bars?
Ans. 
Anchorage of reinforcing bars refers to the method of securing the bars in concrete to ensure proper transfer of forces.
• Anchorage length is the portion of the reinforcing bar embedded in concrete to transfer forces effectively.

• Proper anchorage is crucial for the structural integrity of the concrete element.

• Anchorage can be achieved through hooks, bends, or mechanical anchorage devices.

• Development length is the minimum ...read more

Q2. What is the minimum development length in a column?
Ans. 
The minimum development length in a column is the length required for the full transfer of stress from the steel reinforcement to the concrete.
• The minimum development length is typically specified by design codes or standards.

• It is influenced by factors such as the diameter of the reinforcement, concrete strength, and bond characteristics.

• For example, in ACI 318, the minimum development length for a #5 bar is 12 inches...read more

Q3. What is embedded length and development length?
Ans. 
Embedded length is the length of reinforcement bar embedded in concrete, while development length is the length required for the bar to transfer its load to the concrete.
• Embedded length is the portion of the reinforcement bar that is embedded in concrete to provide structural support.

• Development length is the length of reinforcement required for the bar to transfer its load to the concrete without slippage.

• Embedded len...read more
