Crane Software and Programs. Is if for the design of crane beams. Jim- I believe Crane Beam Designer will design bridge beams as well as runway beams. Crane Runway Beam Minor Unbraced. CRANE RUNWAY BEAM DESIGN' with advantageous and disadvantageous? One of my concern is I need a software only for runway beam. You will learn about the design criteria for crane runway beams and discover the publicly available software and sources for the design of crane girders.

Hi All, I am interested in getting your opinions as to whether or not it is acceptable to consider the wheels of the crane as minor axis brace points for the runway beam. I have always considered the minor axis unbraced length to be the full length of the runway beam but it has just come to my attention that there is a school of thought which calculates the minor axis unbraced length using the crane wheels as brace points with the crane located in a position which generates the maximum moment. It is my understanding that the reasoning behind this is that when the crane beam is fully loaded the opposite crane beam is minimally loaded and therefore has reserve strength to brace the fully loaded beam.

All of your comments have mirrored my feelings. This came up as an optional setting in some design software which suprised me because I had never heared of it being done before. Apparently it is common enough to warrant such a setting and I was curious to learn a little more about how common it really is and how exactly the justification for a lateral brace is made. Thank you all for your input. RE: Crane Runway Beam Minor Unbraced Length (Structural) 30 Jun 10 04:30. Waytsh There is a clause (which escapes me at present) somewhere in the British Standards, which states words to the effect that - you are not allowed `mutual dependency` of any restraint, there must be a positive connection to something solid. Your crane is effectively a mutual restraint to two runway beams with no fixed connection to anything solid and is therefore not acceptable.

So I agree with the other comments and yourself, that you should take the full length of the runway beam. If this length is to great for minor axis bending, one solution is to place a channel section member (toes down) over the top flange of the beam, thereby increasing the section modulus in the lateral direction.
