1.Melemo le mesebetsi ea H-beam ke efe?
Melemo eaH-beam:
Li-flange tse pharaletseng li fana ka khanyetso e matla ea ho khumama le botsitso, ka katleho ho hanyetsa meroalo e emeng; tepo e batlang e phahame e netefatsa khanyetso e ntle ea ho kuta. Moralo ona o fihlella katleho e phahameng haholo ea ts'ebeliso ea thepa, o bobebe ho feta likarolo tse tiileng ka matla a tšoanang a ho jara, 'me o fokotsa boima le litšenyehelo tsa sebopeho. Habohlokoa le ho feta, moralo oa eona o pharaletseng oa flange o etsa hore ts'ebetso e mabapi le lilepe tse matla le tse fokolang li tšoane, 'me ha e sebelisoa e le kholomo, e na le botsitso bo botle ba mahlakore a mabeli' me e khona ho hanela matla a mahlakoreng ka katleho. Ho phaella moo, sebaka se pharaletseng le se sephara sa flange se thusa ho hokahanya le likarolo tse ling (ho tjheseletsa kapa ho kenya bolting), le boholo bo tloaelehileng bo boetse bo nolofatsa moralo le kaho. Ts'ebetso ea eona e felletseng le ts'ebetso e ntle ea litšenyehelo li etsa hore e be sebaka se ratoang sa boleng bo holimo bakeng sa likarolo tsa marang-rang le meaho ea meaho ea sejoale-joale le meaho ea boenjiniere.
Mesebetsi ea H-beam:
Mehaho ea kaho: E sebetsa e le maballo le litšiea limela tsa indasteri le mehaho e phahameng, e nolofalletsang libaka tse telele, tse se nang litšiea (tse kang lifeme le mehaho ea bolulo). Ho satalla ha tsona ho phahameng ho etsa hore li tšoanelehe ho sebelisoa libakeng tse kotsing ea ho sisinyeha ha lefatše.
Meralo ea motheo: Li sebelisoa lits'ebetsong tse kholo kapa tse boima tse kang marokho, litšehetso tsa boema-kepe, le litšitiso tsa litsela tse kholo, hammoho le liqubu tsa tšehetso mererong ea ka tlas'a lefatše.
Thepa e boima le lipalangoang: Li tšehetsa liforeimi tsa literene le likepe, hammoho le mechini e boima, e netefatsang botsitso ba sebopeho.

1.Determine Cross-Section Parameters
Boitsebiso ba Mohlala (ho sebelisa GB/T 11263 e le mohlala):
HW (Wide FlangeTšepe e bōpehileng joaloka H): Flange bophara ≈ bophahamo ba karolo, e loketseng litšiea (e matla biaxial buckling resistance).
HM (Medium Flange H-shaped Steel): Bophara ba Flange bo itekanetse, bo loketse lisebelisoa tse peli tsa borali le kholomo.
HN (Narrow Flange H-shaped Steel): Li-flanges tse tšesaane le li-web tse phahameng, tse loketseng maballo (ho hanyetsa ho kobeha ka tsela e babatsehang).
Tlhaloso ea Mohlala:
HN400×200: Bophahamo ba karolo 400mm, bophara ba flange 200mm.
Khetha lintlha tse tloaelehileng (litšenyehelo tse fokotsehileng le theko e bonolo).
2.Khetho ea Kereiti ea Material
Lisebelisoa tse Tloaelehileng tsa Tšepe:
Q235B: Meroalo e bobebe, lits'ebetso tse theko e tlase.
Q355B (eo pele e neng e le Q345): Khetho e tloaelehileng, e nang le matla a phahameng le katleho e ntle ea litšenyehelo (e khothalelitsoe).
Q420B: Meroalo e boima, meaho ea nako e telele (e kang marokho le maballo a lifeme tsa crane).
Tikoloho e Ikgethileng:Tšepe ea boemo ba leholimo (joalo ka Q355NH) e khothaletsoa bakeng sa tikoloho e senyang. Liaparo tse thibelang mollo lia hlokahala bakeng sa maemo a phahameng a mocheso.
3.Ntlafatso ea Moruo
Unit Weight Bearing Capacity: Bapisa "boima ho mithara ho isa boemong ba ho jara" karo-karolelano ea mefuta e fapaneng, o etelletsa pele likarolo tse fapaneng tse sebetsang hantle.
Boteng ba Mmaraka: Qoba litlhaloso tse sa rateheng (tse nang le linako tse telele tsa ho etella pele le litefiso tse phahameng tsa theko).
Litšenyehelo tsa Tšireletso ea Corrosion: Sebelisa tšepe ea H-beam ea hot-dip bakeng sa meaho e kantle ho fokotsa tlhokomelo e tsoelang pele.
