It is titled "Specifications for Underhung Cranes and
Monorail systems". Our copy is from 1973 and is old.
Refering to section 3.4, the deflection limit...
Dear Doug,
The factor "tau sub xy" is the shear stress in the
beam. It can be calculated using ordinary methods. The
other thing I wanted to point out are that the deflection
limits are different for monorail beams than for crane
girders. The limits are given in a publication by...

Stress & Strain. It has information concerning this type
of calculation. The other is the CMAA publication no. 74
