guy wire design

guy wire design

guy wire design

(OP)
hi!
so im new here and in the civil industry as well.
i was required to determine number of guy wires and its specifications to tie down a retractable/swivel conveyor during typhoons.
this is situated on the dock for loading of copper concentrates. the assumed wind velocity during typhoon is about 312 kph.

i really dont know how to go about this hairpull2

please help me..some guidelines? or examples?

RE: guy wire design

This is not something you should get answers from a remote forum. There are numerous variables that must be considered. Get assistance from a local structural engineer.

RE: guy wire design

seek professional help, maybe your supervisor or a mentor/guru in the office ?

the thing is there are no other structural engr in the company
and this forum was the last option I saw..


Thanks for the replys guys...

RE: guy wire design

New to the civil industry and they threw you to the wolves with this complicated of a project? Sorry buddy, but you need a mentor, in your company. I don't understand companies that do this to their employees and themselves.

RE: guy wire design

Needelson:
It is truly surprising that more engineers and companies don’t get in serious trouble for taking this approach to solving/designing real engineering problems/projects. You should know better, even if your bosses don’t, and you should have the balls (actually engineering ethics) to say you can’t do this without some local and knowledgeable guidance from someone with real experience at this kind of design. Just because they call you an engineer, doesn’t mean you can design anything and everything with out some help, until you actually learn how. While E-Tips is a wonderful place to ask general engineering questions, and to get broad brush answers which give you some general guidance or direction for approaching your problem, there is no way someone half way around the world can see all of the local conditions or understand all of the local variables which should be included in a complete design. And, obviously you don’t know how to pull all of this together either. You should not be doing this project alone, and you should tell your boss you just can’t with your level of experience, but you do want to learn how, with the proper mentoring and guidance.

RE: guy wire design

i reckon mgmt thought (if they thought at all, that is) "if it breaks in a typhoon, then who's to say to wasn't natural (ie storm > spec) ?"

the problem is solvable, though as noted above, this isn't the best place for it. I mean, people have been tieing things down for a long time ...
1) assume a windspeed (maybe a spec value, maybe 100 mph)
2) assume an area it's acting on (maybe lash down every 10', so each lashing reacts W*10*X lbs)
3) develop a Free Body Diagram (to show how the wind load is being reacted)
4) spec guy wires (= lashings) to be Y*the load calc'd in 4) (1<Y<n)

a lot of asusmptions !

ps, leave town before the next typhoon!

RE: guy wire design

I left my first job out of college after about a month because I was put into a somewhat similar situation. The only real engineer at the company was in another state. I knew I needed a daily mentor to really grow in to a good engineer. Best decision of my career.

Sorry Needelson for the tough love, but you have been put into a bad situation. Please follow our advice and talk to your superiors about hiring an experienced engineer, or you may have to try and find a job with a real mentor who can guide you in your career and really teach you the ropes.

Thank you guys!. i will do as advised.

till the next thread then wavey

RE: guy wire design

maybe read the thread "engineer charged in roof collapse"
