The Live Load Min/Max Forces Report shows the envelope of total design live load considering all possible combinations of the design vehicles and the design lanes (up to the maximum number of design lanes). The result also includes the Impact Factor and the Multiple Lane Reduction Factor as specified by IRC6 .

For example, for the IRC_ClassA-70R Locked Library Live Load group, the vehicles considered include: Class A, Class 70R Wheeled, Class 70R Tracked.

The first two Max and Min columns show the maximum positive shear and maximum negative shear. Below these results is the corresponding moment associated with the location of the truck (or portion of the influence line for lane loading) that produced the maximized shear values.

The second two Max and Min columns show the maximum positive moment and maximum negative moment. Below these results is the corresponding shear associated with the location of the truck (or portion of the influence line for lane loading) that produced the maximized moment values.
