Ekuklanyweni kwezakhiwo zensimbi, imisebe ye-H kanye nemisebe ye-I yizona zingxenye eziyinhloko zokuthwala. Umehluko womumo wesigaba esiphambene, usayizi kanye nezakhiwo zemishini kanye nensimu yokusetshenziswa phakathi kwesihloko kumele kuthonye ngqo imithetho yokukhetha ubunjiniyela.
Ngokwethiyori lo mehluko phakathi kwe-I-beams kanye ne-H-beams, ukuma, ukwakheka, kwalesi sici esithwala umthwalo yi-parallel flanges, i-Ibeams encipha ukuze ububanzi be-flange bunciphe ngebanga ukusuka kuwebhu.
Ngokuphathelene nosayizi, imisebe ye-H ingenziwa ngobubanzi obuhlukahlukene be-flange kanye nobukhulu bewebhu ukuze kuhlangatshezwane nezidingo ezahlukene, kuyilapho ubukhulu bemisebe ye-I bufana kakhulu.
Ngokuphathelene nokusebenzaI-H Beam Yensimbiingcono ekumelaneni nokugoba kanye nokuqina kwayo okuphelele nge-symmetrical cross-sectoin, i-I beam ingcono ekumelaneni nokugoba kwemithwalo eceleni kwe-axis.
La mandla abonakala ekusetshenzisweni kwawo: IUgongolo Lwesigaba se-Hingatholakala ezitezi eziphakeme, emabhulohweni, nasemishinini esindayo, kuyilapho i-I beam isebenza kahle ekwakhiweni kwensimbi elula, ozimele bezimoto, kanye nemishayo ye-short-span.
| Ubukhulu Bokuqhathanisa | Ukukhanya kwe-H | I-beam |
| Ukubukeka | Lesi sakhiwo esimise okwe-"H" esimise okwe-biaxial sinezingqimba ezihambisanayo, ubukhulu obufanayo newebhu, kanye nokuguquka okuqondile okubushelelezi kuya kuwebhu. | Isigaba se-I esilinganayo ngokulinganayo esinama-flange anciphile ancipha kusukela empandeni yewebhu kuya emaphethelweni. |
| Izici Ezinobukhulu | Imininingwane eguquguqukayo, njengobubanzi be-flange obulungisekayo kanye nobukhulu bewebhu, kanye nokukhiqizwa ngokwezifiso kuhlanganisa ububanzi obukhulu bemingcele. | Ubukhulu obufanayo, obubonakala ngobude obunqamula izigaba. Ukulungiswa kunqunyelwe, ngosayizi abambalwa abaqinile abanokuphakama okufanayo. |
| Izakhiwo Zemishini | Ukuqina okuphezulu kokugoba, ukuzinza okuhle kakhulu, kanye nokusetshenziswa okuphezulu kwezinto ezibonakalayo kunikeza amandla aphezulu okuthwala umthwalo wobukhulu obufanayo bezingxenye. | Ukusebenza kahle kakhulu kokugoba okuqonde ngqo (cishe i-axis eqinile), kodwa ukuzinza okungekuhle kokugoba nokungaphandle kwendiza, okudinga ukwesekwa noma ukuqinisa ohlangothini. |
| Izicelo Zobunjiniyela | Ifanelekela imithwalo esindayo, ubude obude, kanye nemithwalo eyinkimbinkimbi: ozimele bezakhiwo eziphakeme, amabhuloho amade, imishini esindayo, amafektri amakhulu, ama-auditorium, nokuningi. | Kwemithwalo elula, ama-short spans, kanye nokulayisha okuqonde ngqo: ama-purlin ensimbi alula, ama-frame rails, izakhiwo ezincane ezisizayo, kanye nezisekelo zesikhashana. |
