Ekwakhiweni, ii-I-beams kunye ne-U-beams zimbini iintlobo eziqhelekileyo zentsimbi ezisetyenziselwa ukubonelela ngenkxaso yezakhiwo.Kukho umahluko phakathi kwezi zimbini, ukusuka kwimilo ukuya kwisigxina.
1. I-I-beam ibizwa ngokuba yimilo efana nonobumba "I".Zikwabizwa ngokuba yi-H-beams kuba i-cross-section ye-beam yenziwe njenge "H".Ngelo xesha, imilo ye-U-beam ifana neleta "U", ngoko ke igama.
Olunye ulwahlulo oluphambili phakathi kwe-I-beams kunye ne-U-beams ngumthamo wabo wokuthwala umthwalo.Imiqadi ye-I ngokuqhelekileyo yomelele kwaye yomelele kunee-U-beams, oku kuthetha ukuba zifaneleke kangcono ukuphatha imithwalo enzima kunye nokuxhasa izakhiwo ezinkulu.I-U-beams ilungele iiprojekthi ezincinci ezifana nezakhiwo zokuhlala.
Omnye umahluko phakathi kwemiqadi emibini kukuguquguquka kwayo.I-I-beams ngokubanzi iguquguqukayo kune-U-beams, eyenza ibe yinto efanelekileyo yokusetyenziswa kwizakhiwo ezigobileyo.I-U-beams, kwelinye icala, ziqinile kwaye aziguquki kangako, ngoko ke zingcono kwiiprojekthi ezifuna imigca ethe tye.
Ukuqina yenye into eyahlula i-I-beams ukusuka kwi-U-beams.Imiqadi ye-I yenziwe ngentsimbi eyomeleleyo kune-U-beams, oku kuthetha ukuba ayinakukwazi ukugoba okanye ukuguqula phantsi koxinzelelo.I-U-beams, kwelinye icala, iyathandeka kakhulu ekujikeni kunye nokugoba, ngakumbi xa ibonakaliswe kumaqondo obushushu agqithisileyo.
Ukudibanisa, ii-I-beams kunye ne-U-beams zimbini iintlobo zentsimbi ezisetyenziswa ngokuqhelekileyo ekwakheni.Nangona kukho ukungafani phakathi kwezi zibini ngokwemilo, ukuthwala umthwalo, ukuguquguquka kunye nokuqina, zombini zizinto ezibalulekileyo zokubonelela ngenkxaso yezakhiwo.Ukukhetha umqadi ofanelekileyo weprojekthi kuxhomekeke kwiimfuno ezithile kunye neemfuno zokwakhiwa.
