Topic Notes and a review item from the same lesson.

Use what you know.

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

Temporary pedestrian bridge review

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.

A scenario with context, an open response and a consequence.

Come back knowing what to do next.

Today brings together the lesson to continue, the review that is due and the scenario you are ready for.
