My company manufactures patented track crane and monorail systems. Sometimes the track must be flush clamped to the building steel, and the attached sketch is a sample of one of our lowest capacity clamps.
The clamp, for example, may be rated for 10,000#, but depending on the hanger centers, and whether the clamp is at a splice location, as the loaded trolleys approach the clamp the load on one side will be greater than half the clamp's stated capacity. In designing the clamps, this load is assumed to act at the point shown at the arrow, with X3 being 2/3 of the clamp-steel contact surface. The clamps on the underside may transfer some of the load to the other side, but we haven't factored that into the design.
Is there a way to determine if and how much of the load is transferred? If I need to design a special clamp, at worst case I could ignore the transferred load and design the upper clamp with the full load. I just wondered if there's a more accurate way of doing it.
Thanks.
