Q1. What is mean by shear key
Ans. 
Shear key is a device used to transfer shear forces between two components in a structure.
• Shear keys are typically used in construction joints to prevent sliding between adjacent components.

• They are designed to resist horizontal forces and ensure stability.

• Shear keys can be found in structures such as bridges, buildings, and dams.

• Examples include shear keys in bridge expansion joints to prevent movement between bridge

Q2. Different between columns and beams
Ans. 
Columns are vertical structural members that support loads, while beams are horizontal members that transfer loads to columns or walls.
• Columns are vertical and primarily support compressive loads.

• Beams are horizontal and primarily support bending loads.

• Columns are typically taller than they are wide, while beams are typically wider than they are tall.

• Examples: In a building, columns support the weight of the floors abo...read more

Q1. Design of one way slab
Ans. 
One way slab is a type of reinforced concrete slab where the main reinforcement is provided in only one direction.
• Main reinforcement is provided in the shorter span direction

• Distribution bars are provided in the longer span direction

• Commonly used in buildings with rectangular floor plans

Q2. Difference between short column and long column
Ans. 
Short columns fail due to crushing of material, while long columns fail due to buckling.
• Short columns have a slenderness ratio less than a certain critical value, while long columns have a slenderness ratio greater than that value.

• Short columns are more likely to fail in compression, while long columns are more likely to fail in buckling.

• Examples of short columns include columns in buildings, while examples of long col

Q3. Design of two way slab
Ans. 
Two way slab is a type of reinforced concrete slab that is supported by beams in both directions.
• Two way slab is designed to carry loads in both directions, typically used in buildings with square or rectangular floor plans.

• The design of two way slab involves determining the thickness, reinforcement layout, and spacing of bars to ensure structural integrity.

• The slab is supported by beams on all four sides, allowing for...read more

Q4. Design of staircase
Ans. 
Designing a staircase involves considering factors such as building codes, safety regulations, space constraints, and aesthetic appeal.
• Consider the height and width of each step to ensure comfortable and safe use.

• Calculate the rise and run of the staircase to determine the number of steps needed.

• Choose a suitable material for the staircase based on the design requirements and budget.

• Ensure proper handrails and guardrai...read more

Q1. BMD and SFD diagram of continuous beam and portal frames.
Ans. 
BMD and SFD diagrams show internal forces in a structure, like bending moment and shear force.
• BMD diagram displays variation of bending moment along the length of a beam or frame.

• SFD diagram shows variation of shear force along the length of a beam or frame.

• In continuous beams, BMD and SFD diagrams help in analyzing internal forces at different supports and sections.

• Portal frames have different loading conditions which...read more

Q4. Plastic method of design
Ans. 
Plastic method of design is a structural engineering approach that considers the redistribution of internal forces to achieve a more efficient design.
• Plastic method allows for redistribution of internal forces beyond the elastic limit of the material.

• It is based on the concept of plastic hinges forming in the structure to dissipate energy.

• Design is based on achieving a collapse mechanism that is ductile and predictable...read more
