Per the subject title, what we have is a 20ft tall mast on a hospital roof with 3 guy lines attached near the top. They are not spaced equilaterally, but let's assume they are, and each guy is of varying length and vertical slope since they attach to accessible column stub-ups on surrounding...
I put quotations around the key phrase to hopefully help future structural engineers out (assuming this thread can generate some answers!) - as a google search of the thread's title + site:eng-tips.com generated 0 hits.
My specific question relates to the common structural engineering practice...
Is there a quick way to estimate lateral deflection in a moment frame? Like say you have a portal frame fixed at the base and at all connections, dummy lateral load at the top, find the deflection within 30 seconds (without a computer - Im studying for the SE).
I get estimating the inflection...
A quick background to the problem: A client of ours is experiencing floor heaving in their pre-manufactured steel building due to pockets of slag under the spread footings. Because of this, a few of the steel columns have deflected over the last couple years. This company hired us to perform a...
I am a recent grad, entry level structural engineer. A problem recently came up at work, where a client wants to drive a 6-axle, 180k drill rig over a 75ft span single lane bridge (with ends fixed in concrete headwall).
Is it ok to analyze this bridge assuming a single pass of the drill rig...
