Given:
Degrees of indeterminacy = 2
To find:
Number of plastic hinges at complete collapse
Solution:
What are plastic hinges?
Plastic hinges are the locations where the bending moment in a structural member is maximum and the member begins to yield plastically. Once a plastic hinge is formed, the bending moment remains constant and the hinge rotates freely.
When does complete collapse occur?
Complete collapse of a structure occurs when all the plastic hinges in the structure have formed.
How to determine the number of plastic hinges in a structure?
The number of plastic hinges in a structure can be determined using the following formula:
Number of plastic hinges = (Degrees of indeterminacy) + 1
Therefore, in this case, the number of plastic hinges at complete collapse would be:
Number of plastic hinges = (2) + 1 = 3
Hence, the correct answer is option A.
