Solid Plate Deflection

  1. Mar 11, 2008 #1
    I am placing a small crane on a concrete deck. The deck live load is 760psf. The crane is 17,260lbs. Each outrigger base plate contacting the deck has a surface area of .75 sq. ft. This gives a load of about 5753lb on each base plate. I am going to use steel plate (A36 plate) under the outrigger base to spread out the load. To determine how thick the plate needs to be I believe I need to determine the deflection of the plate to ensure the ends don't turn up and concentrate the load on an area smaller than the whole plate. This plate sits in a flat concrete deck and I am not sure how to determine the deflection. I am familiar with beam loading to some extent and need to know if I would figure this like a beam. Thanks.
