Ob leeg I-beam thiab H-beam yog ntau yam thiab tuaj yeem siv rau ntau yam kev siv.
Lawv yog ob qho tib si structural steel beams uas tau tsim los pab txhawb rau cov tsev thiab lwm yam qauv.
Qhov sib txawv tseem ceeb ntawm ob hom kab teeb no yog lawv cov duab. Ib qho "I" beam muaj ib daim duab peb sab cross-section, thaum lub "H" beam muaj ib lub duab plaub (li no lub npe).
Lwm qhov sib txawv ntawm lawv yog tias "H" beam feem ntau ntev dua "I" beam ntawm qhov loj me thiab qhov hnyav. Qhov no txhais tau hais tias H-beam yuav siv ntau qhov chaw thaum ntsia, tab sis nws kuj muaj zog ntau dua thaum nqa cov khoom hnyav dhau qhov ntev lossis ntev; whereas I-beam tej zaum yuav zoo dua rau kev tuav cov khoom me me ntawm qhov luv luv luv vim nws muaj zog ntxiv (tsawg dua).
Raws li qhov tshwm sim, H beams feem ntau suav hais tias yog qhov ruaj khov dua li kuv cov kab teeb vim lawv qhov hnyav dua thiab tawv. Txawm li cas los xij, muaj ntau qhov sib txawv uas tuaj yeem cuam tshuam lub nqaj lub zog thiab kev ua tau zoo, nrog rau nws cov txheej txheem tsim khoom, muaj pes tsawg leeg, thiab tsim. Thaum kawg, nws yog nyob ntawm ib tus kws tshaj lij thiab cov neeg tsim qauv xaiv cov kab teeb uas zoo tagnrho rau ib lub hom phiaj.
