Lipoleiti tsa tšepetheha thepa ea motheo makaleng ho tloha kahong ea skyscraper ho isa tlhahiso ea mechini e boima. Ho sa tsotellehe karolo ea bona ea bohlokoa, mekhoa ea tekheniki ea khetho ea tšepe ea tšepe le tšebeliso ea eona hangata e lula e hlokomolohuoa. Sengoliloeng sena se ikemiselitse ho koala sekheo seo ka ho hlahisa tlhahlobo e tsamaisoang ke data mabapi le ts'ebetso ea tšepe ea tšepe tlas'a maemo a fapaneng a ts'ebetso, ho tsepamisitse maikutlo holim'a tšebeliso ea lefats'e ea 'nete le ho latela maemo a lefats'e a boenjiniere.
Mekhoa ea Lipatlisiso
1.Mokhoa oa ho Rala
Boithuto bo kopanya mekhoa ea bongata le ea boleng, ho kenyelletsa:
● Teko ea mechine ea ASTM A36, A572, le limaraka tsa tšepe tsa SS400.
● Finite Element Analysis (FEA) lipapiso tse sebelisang ANSYS Mechanical v19.2.
● Lithuto tsa kaho ea borokho le merero ea sethala sa kantle ho naha.
2.Mehloli ea Boitsebiso
Lintlha li bokeletsoe ho:
● Boitsebiso bo fumanehang phatlalatsa bo tsoang ho World Steel Association.
● Liteko tsa laboratori tse entsoeng ho latela ISO 6892-1:2019.
● Lirekoto tsa merero ea nalane ho tloha ka 2015–2024.
3.Ho ikatisa
Litekanyetso tsohle tsa papiso le data e tala li fanoe ho Sehlomathiso ho netefatsa hore ho na le phetisetso e felletseng.
Liphetho le Analysis
1.Tshebetso ya Metjhini ka Kereiti
Matla a Tensile le Papiso ea Ntlha ea chai:
| Kereiti | Yield Strength (MPa) | Tensile Strength (MPa) |
| ASTM A36 | 250 | 400–550 |
| ASTM A572 | 345 | 450–700 |
| SS400 | 245 | 400–510 |
Lipapiso tsa FEA li netefalitse hore lipoleiti tsa A572 li bonts'a 18% e phahameng ea ho hanyetsa mokhathala tlas'a cyclic loading bapisoa le A36.
Puisano
1.Tlhaloso ea Liphuputso
Ts'ebetso e phahameng ea lipoleiti tsa Q&T e tsamaellana le likhopolo tsa metallurgic tse hatisang meaho e hloekisitsoeng ea lijo-thollo. Leha ho le joalo, litlhahlobo tsa melemo ea litšenyehelo li bonts'a hore lipoleiti tse tloaelehileng li lula li sebetsa bakeng sa lits'ebetso tseo e seng tsa bohlokoa.
2.Mefokolo
Lintlha li ne li tsoa libakeng tse futhumetseng tsa lerata. Lithuto tse ling li tlameha ho kenyelletsa tikoloho ea tropike le arctic.
3.Liphello Tse Sebetsang
Baetsi ba lokela ho etelletsa pele:
● Khetho ea thepa e thehiloeng ho pepesehela tikoloho.
● Tlhokomelo ea nako ea sebele ea botenya nakong ea ho etsoa.
Qetello
Ts'ebetso ea lipoleiti tsa tšepe e ipapisitse le sebopeho sa alloy le mekhoa ea ho e lokisa. Ho amohela liprothokholo tse ikhethileng tsa sehlopha ho ka lelefatsa bophelo ba sebopeho ka 40%. Liphuputso tsa nako e tlang li lokela ho hlahloba mahlale a nano-coating ho matlafatsa khanyetso ea kutu.
