Iintambo zothumelo zenziwe ngamacandelo amahlanu aphambili: ii-conductor, izifakelo, izigqudu, iinqaba kunye neziseko.Iinqaba zothumelo ziyinxalenye ebalulekileyo yokuxhasa iintambo zothumelo, ezibalelwa ngaphezulu kwe-30% yotyalo-mali lweprojekthi.Ukukhethwa kohlobo lwenqaba yothumelo kuxhomekeke kwindlela yothumelo (isekethe enye, iisekethe ezininzi, i-AC/DC, i-compact, inqanaba lombane), iimeko zomgca (isicwangciso ecaleni komgca, izakhiwo, izityalo, njl. njl.), iimeko zejoloji, iimeko zomhlaba kunye iimeko zokusebenza.Uyilo lweenqaba zothumelo kufuneka zihlangabezane nezi mfuno zingentla, kwaye ziyilwe ngononophelo ngokusekelwe kuthelekiso olubanzi lobugcisa kunye noqoqosho ukuze kuphunyezwe ukhuseleko, uqoqosho, ukhuseleko lokusingqongileyo kunye nobuhle.
(1) Iimfuno zokucwangciswa kwenqaba yothumelo kunye nokukhetha ukuhlangabezana neemfuno zombane:
1. Ukukhutshwa kombane
2.Isithuba somgca (isithuba somgca othe tye, isithuba somgca othe nkqo)
3.Ukufuduka phakathi kwemigca emeleneyo
4.I-angle yokukhusela
5.Ubude bentambo
I-angle ye-6.V-string
7.Ubude bobude
8.Indlela yokuncamathela (uncamathiselo olunye, uncamathiselo kabini)
(2) uPhuculo loLwakhiwo loLwakhiwo
Uyilo lwesakhiwo kufuneka luhlangabezane neemfuno zokusebenza kunye nokugcinwa (njengokuseka iileli, amaqonga, kunye neendlela zokuhamba), ukucubungula (okufana nokuwelda, ukugoba, njl.), kunye nofakelo ngelixa uqinisekisa ukhuseleko.
(3) Ukukhethwa kwezinto
1. Ulungelelaniso
2. Iimfuno zesakhiwo
3. Ukunyamezela okufanelekileyo kufuneka kuthathelwe ingqalelo kwiindawo zokuxhoma (zixhomekeke ngokuthe ngqo kwimithwalo eguquguqukayo) kunye neendawo eziguquguqukayo ze-slope.
4. Izixhobo ezinama-angles okuvula kunye ne-eccentricity yesakhiwo kufuneka ibe nokunyamezela ngenxa yeziphene zokuqala (ukunciphisa umthamo wokuthwala).
5. Makusetyenziswe isilumkiso ekukhethweni kwezinto eziphathekayo kumacandelo e-parallel-axis, njengoko iimvavanyo eziphindaphindiweyo zibonise ukungaphumeleli kwaloo macandelo.Ngokuqhelekileyo, ubude bokulungiswa kobude be-1.1 kufuneka kuthathelwe ingqalelo kumacandelo e-axis ehambelanayo, kunye nokungazinzi kwe-torsional kufuneka kubalwe ngokwe "Steel Code."
6. Izinto eziqinileyo zentonga kufuneka zingene ekungqinisisweni kokucheba iibhloko.
