Allowable crane traction frame drift?
Allowable crane traction frame drift?
(OP)
I have a building I designed to accommodate a 15ton pendant operated bridge crane. The project ran over budget and the client decided to reduce the size of his building. Unfortunately the portion of the building he decided to eliminate contained a brace used to resist traction forces of the crane. I am now being asked to design a frame that will allow the space under the crane to be open (a moment frame). So I am wondering what the allowable drift of this frame should be?
I am considering using H/400 but I am not sure if this is even correct. All of the literature I have relates to deflection of the crane girder and drift of the building perpendicular to the crane runway but I have yet to come across anything that gives this limit.

I believe H/400 is the right number.
