Ekuqulunqweni kwezakhiwo zetsimbi, ii-H-beams kunye ne-I-beams zizona nxalenye eziphambili zokuthwala. Ukwahluka kobume becandelo lomnqamlezo, ubungakanani kunye neempawu zomatshini kunye nentsimi yesicelo phakathi kwesifundo kufuneka kube nefuthe ngqo kwimithetho yokukhetha ubunjineli.
Ngokwethiyori lo mahluko phakathi kwe-I-imiqadi kunye ne-H-imiqadi, imilo, ukwakhiwa, le nqwelo-moya ethwele umthwalo yi-flanges ehambelanayo, i-Ibeams e-tapers ngoko ububanzi be-flange buyancipha kunye nomgama ukusuka kwiwebhu.
Ngokumalunga nobukhulu, imiqadi ye-H inokwenziwa kunye nobubanzi obuhlukeneyo be-flange kunye nobukhulu bewebhu ukuhlangabezana neemfuno ezahlukeneyo, ngelixa ubukhulu be-I-beams bungaphezulu okanye buncinci.
Ngokwemigaqo yokusebenza iIntsimbi H Beamingcono kuxhathiso lwe-torsional kunye nobulukhuni buphelele kunye ne-symmetrical cross-sectoin, umqadi we-I ungcono ekugobeni ukuxhathisa imithwalo ecaleni kwe-axis.
La mandla abonakaliswa kwizicelo zabo: IH Icandelo Beaminokufumaneka kwiindawo eziphakamileyo, iibhulorho, kunye nezixhobo ezinzima, ngelixa i-beam ye-I isebenza kakuhle kulwakhiwo lwentsimbi olulula, iifreyimu zezithuthi, kunye nemiqadi emifutshane.
| Imilinganiselo yokuthelekisa | H-umqadi | I-beam |
| Imbonakalo | Esi sakhiwo simise okwe-biaxial "H" sineeflange ezihambelanayo, ubukhulu obulinganayo kwiwebhu, kunye nokuguquguquka okuthe nkqo kwiwebhu. | I-uniaxially symmetrical-section ye-I ene-tapered flanges ejikelezayo ukusuka kwingcambu yewebhu ukuya emaphethelweni. |
| Iimpawu zoMda | Iimpawu eziguquguqukayo, ezifana nobubanzi beflange obuhlengahlengiswayo kunye nobukhulu bewebhu, kunye nemveliso yesiko igubungela uluhlu olubanzi lweeparamitha. | Imilinganiselo yemodyuli, ebonakaliswe ngobude obunqamlezayo. Ukulungelelaniswa kulinganiselwe, kunye neesayizi ezimbalwa ezizinzileyo zobude obufanayo. |
| Iipropati zoomatshini | Ukuqina okuphezulu kwe-torsional, uzinzo olugqwesileyo jikelele, kunye nokusetyenziswa okuphezulu kwemathiriyeli kuvelisa umthamo ophezulu wokuthwala umthwalo wemilinganiselo efanayo yamacandelo. | Ukusebenza okugqwesileyo kokugoba kwe-unidirectional (malunga ne-axis eyomeleleyo), kodwa ukungahambi kakuhle kwe-torsional kunye nozinzo olungaphandle kwendiza, olufuna inkxaso yecala okanye ukuqiniswa. |
| Izicelo zobuNjineli | Ifanele imithwalo enzima, i-spans emide, kunye nemithwalo enzima: iifreyimu zezakhiwo eziphakamileyo, iibhulorho ezide, umatshini onzima, iifektri ezinkulu, iiholo, kunye nokunye. | Imithwalo elula, i-spans emfutshane, kunye nokulayishwa kwe-unidirectional: i-purlins yensimbi elula, iileyili zefreyimu, izakhiwo ezincinci ezincedisayo, kunye nezixhaso zexeshana. |
