Due tomorrow
A scenario puts you in a situation where you have to make a decision, explain your thinking and see what follows.
Scenarios
Structural loads
Scenario · Structural loads
You are helping inspect a temporary pedestrian bridge after its expected load increases. The original support design was calculated for a lighter load. Explain what needs to be reconsidered before the bridge can be approved.
Your response
I would recalculate the support reactions for the new load case, check the safety factor on the critical member, and…
What follows
Approval is delayed until the revised load case is documented. The Tutor asks which assumption in the original design no longer holds.
Today brings together the lesson to continue, the review that is due and the scenario you are ready for.
