QUESTION: Lp and Ln in Leap Bridge steel connector report mean?

ANSWER:

Location of maximum positive LL+I moment (Max Live Load) relative to the POI location is determined 

For continuous spans:

End spans:

• Lp – Distance (arc length for curved bridge) from beginning of span to Max Positive Live Load location
• Ln1… – Distance from Max Positive Live Load location to interior support

Interior spans will have 2 Ln values. 

• One is the distance from Max Positive Live Load location to the back interior support (Ln2…)
• and the other is the distance from Max Positive Live Load location to the ahead interior support (Ln3…)
