Add a bridge component to record its inputs, capacity and governing check.
Learning objectives
- Apply AASHTO LRFD live load
- Distribute load to girders
- Check strength and service limit states
Engineering judgment
- HL-93 is a notional load, not a real truck.
- Check fatigue and deflection, not just strength.
