A
= ∑P * 𝛿
2
Q
How is internal work calculated?
A
= ∑ M_p * θ
3
Q
What happens when there are multiple collapse mechanisms?
A
- Find the most critical one
4
Q
How can the most critical collapse mechanism be found?
A
Lowest load factor
5
Q
What does the load factor depend on?
A
Depends on the relative magnitudes of the loads, the span size and number of hinges
