Question 1.
What is shear failure?
Show hintHide hint
Think of a beam breaking under horizontal forces.
Question 2.
What visual clue is often associated with shear failure in concrete?
Show hintHide hint
Consider how forces act on a beam.
3Question 3.
What is the primary cause of shear failure in concrete?
- Insufficient shear reinforcement
- Too much concrete
- Improper mixing
Show hintHide hint
Consider the function of reinforcement.
4Question 4.
True or False: Shear failure can occur without any prior warning.
- True
- False
Show hintHide hint
Reflect on the nature of failure.
Question 5.
A new concrete beam is designed to hold a significant load. Calculate the shear reinforcement needed if the beam's dimensions are 200 mm height and 300 mm width, under a shear force of 50 kN, using standard shear design principles.
Show hintHide hint
Apply shear design principles as per the standard codes.
Question 6.
Analyze an existing structure where shear failure occurred. Identify potential flaws in design or construction that may have led to this failure, and suggest remedial measures.
Show hintHide hint
Think critically about design safety.
