Identification of Cracks

Q1

A

• This is flexural failure occured during the earthquake due to reversal of stress
• so the bottom of the beam experiences tension and the top experiences compression
• This due also due to in adiquate reinforcement in the bottom section
• so it is not repairable

B

• This is pull out failure due to insufficient of development lenght og the reinforcement
• so the beam looks like deatached from the column
• so it is not repairable

C

• It is due to cyclic lateral load and the slab are subjected to stress so they formed a cracks along the span direction
• This can be strengthened

Q2

A

• This is due to plastic hinge formation
• It is Also occured due to Inadiquate design
• it may repairable

B

• This is due to Shear failure
• Inadiquate shear reinforcement

C

• It is a short column failure
• This is due to heavyload from the additional slab added to the column
• The failure is not repairable
