Ekwakhiweni, imishayo ye-I kanye ne-U-imishayo yizinhlobo ezimbili ezivamile zensimbi ezisetshenziselwa ukusekela izakhiwo.Kunomehluko othile phakathi kwalokhu okubili, kusukela ekubunjweni kuya ekuqineni.
1. I-I-beam iqanjwe ngesimo sayo esifana nohlamvu “I”.Zibuye zaziwa ngokuthi ama-H-beams ngoba ingxenye ephambanayo ye-beam yakheke njengo-“H”.Ngesikhathi esifanayo, ukuma kwe-U-beam kufana nohlamvu "U", ngakho-ke igama.
Omunye umehluko omkhulu phakathi kwe-I-beams ne-U-beams amandla abo okuthwala umthwalo.Ama-I-beam ngokuvamile anamandla futhi anamandla kune-U-beams, okusho ukuthi afaneleka kangcono ukuphatha imithwalo esindayo nokusekela izakhiwo ezinkulu.I-U-beams ilungele amaphrojekthi amancane njengezakhiwo zokuhlala.
Omunye umehluko phakathi kwemishayo emibili ukuguquguquka kwayo.Ama-I-beam ngokuvamile aguquguquka kakhulu kune-U-beams, okuwenza alungele ukusetshenziswa ezakhiweni ezigobile.I-U-beams, ngakolunye uhlangothi, iqinile futhi ayiguquguquki kancane, ngakho-ke ingcono kumaphrojekthi adinga imigqa eqondile.
Ukuqina kungenye into ehlukanisa ama-I-beams ku-U-beams.Ama-I-beams enziwe ngensimbi enamandla kune-U-beams, okusho ukuthi mancane amathuba okuthi agobe noma aguge ngaphansi kwengcindezi.I-U-beams, ngakolunye uhlangothi, ijwayele ukugoqa futhi igobe, ikakhulukazi lapho ibhekene namazinga okushisa aphezulu.
Ukufingqa, imishayo ye-I kanye ne-U-imishayo yizinhlobo ezimbili zensimbi ezivame ukusetshenziswa ekwakheni.Nakuba kunomehluko othile phakathi kwalokhu okubili mayelana nokuma, ukuthwala umthwalo, ukuguquguquka nokuqina, kokubili kuyizingxenye ezibalulekile zokuhlinzeka ngokusekela izakhiwo.Ukukhetha ugongolo olufanele lwephrojekthi kuncike ezidingweni ezithile kanye nezidingo zokwakha.
