✔✔What is the greatest concern with truss construction?
Expense, as they are more costly than solid beams.
Greater surface area allows more chance of catching fire.
Failure at one point produces a failure in the entire truss.
They must be unprotected, because no protected materials can attach to the truss. -
✔✔Failure at one point produces a failure in the entire truss.
✔✔Flashover will occur in contemporary structures more often and quicker due to which
factor?
