How can I determine the capacity of an old asphalt test track road to support a gantry crane? I have a recent Geotech report from an adjacent building. In-situ bearing capacity is 2500 psf at a depth of 1-2ft and 4000psf at 2-4ft. I need to unload a piece of equipment with a temporary gantry...
Thank you for the quick response JAE. I dug up my old university textbook from 2009 in an effort to defend my original thought. My text book suggests KL/r,min < 300 for tension members where L is unbraced length. But contradicts itself when it refers back to AISC 360 section D1 which only says...
Suppose an x brace made of two equal leg angles connected at the intersection. Tension members only. Which radius of gyration governs when checking the total length of the member for KL/R slenderness? I spoke with a senior structural engineer at my company and was advised that two of the three...
