so what i am hearing from Jed is that code design of an exterior crane for wind doesn't mean accelerating the crane over the length of the runway, but just applying a wind force to the stop such as that applied to the ends of a simply supported beam...ie crane = simply supported beam.
Thanks JedClampett. The owner has asked us to analyze an existing stop that has been designed for this crane and determine if it is adequate. The request was to make sure it is overly designed since the reason they are having to purchase another crane is that the original one was blown over in...
I am in the process of designing an end stop for an exterior overhead double girder bridge crane application. I am fairly confident in determining the collision force that the end stop needs to be designed for based on the Kinetic Energy Equation (1/2*W*v^2/g*S), however please correct me if I...
I have also been working on the model with JTPE and like the idea of removing the node at the crossing of the x-braces that seem to be exceeding their Euler buckling limit. I will try this and see what occurs.
unfortunatly, I am unable to interconnect the two individual footings with a grade beam due to another pair of columns with footings between the two carbis columns. thanks for the input.

The moment is due to the column being one of two supports of a cantilevered carbis truck access system where most of the load is vertical on the platform of the carbis system therefore causing the moment at the column base. There are wind loads that occur laterally, the worst case causing...
I have a footing that is subjected to a rather small vertical load, a rather large moment, and with site constraints keeping the footing from being symetrical about the center of the column. The current design example I am using to design this footing bases the design off of a symetrical...
