Wheel Reaction Factor formerly called Multi-Floor Beam Only Option
Floorbeam live loads may be reduced using the Description > General Member Information > (Wheel Reaction Factor) option – as shown below.
This option is used when the floorbeams are spaced closely together and only a portion of the wheel loading is considered to be on the floorbeam. In this case, the use of (Wheel Reaction Factor) = 0.500 will reduce the live load effect on the floorbeam by 50%.
An alternate use would be to simulate a continuous span stringer and increase the reaction, in the example below 1.13 is used.
