QUESTION: How to manually verify the deflection reported for LGA Live Load Deflection load case?

 

This is how user can verify the deflection reported for LGA LL Deflection load case:

 Example:

After running the LGA for G2 including LL: The Deflection values shown in the screenshot is -1.80 in.

User needs to go to lane loading details and see the live load configuration for that Live Load case:

From the vehicle effect user can get the IM and LLDF (shear -ve) value, then we should be able to match the reported deflection = 1.142” * 1.33 * 1.1864 = -1.8”.
