In our country, ASD is still being used. As far as I know, our structural code for steel has not been change but we are allowed to use LRFD which is now being taught in some universities.
We dont have ice here but we have strong winds. Unless our electrical code adapted some provisions of...
Well, honestly, I live in a third world country and I find it difficult to obtain a copy of ASCE 74.I have a limited resource, in fact, our currency is equivalent to more or less 50x one U.S. dollar.
I do not work for any company engage in power distribution or transmission. I just want to...
Halu to everyone!!If I were to design a transmission structure, what are the load combination that I will use related to the Longitudinal Load for ASD and LRFD. Is there a specific load factor for each method (RSL, BPA or EPRI method)?Well, I have a limited knowledge about ASCE 74 and I havent...
Well, I'm not a member of the ASCE & I cannot join the conference because I live here in some part of Asia.
Is the RSL mainly related to everyday tension loading or does it consider wind loading also in the computation?
I think there a need to analyze and design both tower types to determine which is cheaper.There are lots of factors affecting the cost of tower. One factor is the design method (ASD or LRFD) you use.The type of conductor you use will also affect the cost of your structure.
What I mean is how do they calculate the sag and tension of a new trasnsmission line, 230 KV, with a ruling span of 1000ft and a maximum wind velocity of 200 KPH.
I want to calculate it by hand (using spreadsheet).
Hi!
I dont know the procedure in calculating conductor sag and tension of a new transmission line, could anybody help.
Is there any criteria on selecting what sag(on the sag tension table) will be used in determining the height of the transmission tower?
