Lub zog ntawm I-beam thiab H-nqaj nyob ntawm ntau yam, suav nrog lawv qhov ntev, cov khoom siv, thiab lawv siv li cas hauv ib qho kev ua haujlwm tshwj xeeb. Ob leeg I-beams thiab H-beams yog tsim los muab lub zog siab, tab sis lawv cov yam ntxwv ntawm lub zog tuaj yeem sib txawv raws li cov xwm txheej no.
Feem ntau, H-beams zoo li muaj peev xwm thauj khoom ntau dua li I-beams ntawm tib qhov hnyav thiab cov khoom siv vim lawv cov duab sib luag nrog qhov sib npaug-dav flanges thiab lub web tuab. Qhov no symmetry tso cai rau H-beams faib loads ntau tusyees nyob rau hauv ob qho tib si ntsug thiab kab rov tav cov lus qhia, ua rau lawv zoo dua haum rau daim ntaub ntawv uas muaj ob hom loads.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub zog tiag tiag ntawm ib qho nqaj yog nyob ntawm nws qhov ntev thiab cov khoom siv los ntawm qhov nws tau tsim. Cov kws tsim qauv xaiv cov kab teeb pom kev zoo thiab cov khoom siv raws li cov qauv kev xav tau ntawm ib qhov project, xav txog yam xws li kev ncua ntev, kev xav tau ntawm cov khoom thauj, cov yam ntxwv ntawm kev nyab xeeb, thiab cov qauv siv hauv tsev thiab cov qauv.
