2. Zoo dua qhov hnyav thiab kev xa khoom zoo
Rau cov neeg yuav khoom thoob ntiaj teb tab tom nrhiav rau A572 H beam cov chaw muag khoom, qhov hnyav ua lub luag haujlwm tseem ceeb hauv kev xa khoom.
A36 xav tau cov ntu hnyav dua
A572 tso cai rau lwm qhov sib dua
Qhov tshwm sim:
Txo qhov ntim khoom thauj
Tus nqi thauj khoom qis dua ib qhov project
Qhov no yog vim li cas A572 H beam luj daim ntawv feem ntau yog siv thaum lub sij hawm yuav khoom optimization.
3. Tag Nrho Tus Nqi vs Nqe Ib Tuj
Ib qho kev xav tsis zoo yog tias A36 pheej yig dua.
Txawm li cas los xij:
A36 → qis tus nqi ib tuj, tab sis ntau dua yuav tsum tau
A572 → tus nqi siab dua ib tuj, tab sis qis tag nrho kev siv
Hauv qhov project tiag tiag:
A36 nce tag nrho cov khoom siv
A572 txo tag nrho cov nqi nruab
Qhov no ua rau A572 H beam yog tus nqi ntau dua -kev daws teeb meem
A36 H Beam Sizes vs A572 H Beam Loj: Lawv Puas Hloov Tau?
Los ntawm qhov pom ntawm qhov pom:
- A36 H beam qhov ntev thiab A572 H beam qhov ntev ua raws li cov qauv zoo sib xws (ASTM profiles)
- Txawm li cas los xij, lawv tsis tuaj yeem hloov pauv ncaj qha yam tsis muaj kev suav rov qab
Lus Cim Tseem Ceeb
Tsuas yog hloov A36 nrog A572 yam tsis muaj kev tsim kho tshiab tuaj yeem:
- Cov khoom siv pov tseg
- Tshem tawm cov nqi zoo
Engineers feem ntau:
- Recalculate load xav tau
- Optimize seem loj siv A572 lub zog
Daim Ntawv Thov: Thaum Siv A36 vs A572 H Beam
A36 Cov Qauv H Beam
Feem ntau siv rau:
- Kev tsim kho dav dav
