I-Granite, eyaziwa ngobulukhuni bayo obungavamile, ukuqina kwayo, kanye nokukhanga kwayo okuhle, isetshenziswe kabanzi hhayi nje kuphela njengezinto zokuhlobisa kodwa futhi njengengxenye yesakhiwo ekusetshenzisweni okunembile kanye nokwakha. Ekwakhiweni kwesakhiwo kwanamuhla, indlela yokuthuthukisa ukusebenza kahle kwesakhiwo ngokwenza ngcono ukuma kwe-cross-sectional ye-granite beams isibe yisihloko esibaluleke kakhulu, ikakhulukazi njengoba izimboni ziphishekela kokubili izakhiwo ezilula kanye nokusebenza kahle kwemishini.
Njengenye yezinto eziyinhloko ezithwala umthwalo ekwakhiweni kwezakhiwo kanye nasezisekelweni zemishini enembile, ukwakheka kwe-granite beam okuyingxenye kuthinta ngqo amandla ayo okuthwala umthwalo, isisindo sayo, kanye nokusetshenziswa kwezinto. Izingxenye zendabuko eziyingxenye—njengezimo ezimise okwesikwele noma ezimise okwe-I—sekuyisikhathi eside zihlangabezana nezidingo zesakhiwo eziyisisekelo. Kodwa-ke, ngokuthuthuka kwezindlela zokubala kanye nesidingo esikhulayo sokusebenza kahle, ukwenza ngcono lezi zimo eziyingxenye kube yinto ebalulekile ukuze kufezwe ukusebenza okuphezulu ngaphandle kokusetshenziswa kwezinto ezingadingekile.
Ngokombono wesakhiwo, ingxenye efanelekile ye-granite beam kufanele inikeze ukuqina namandla anele ngenkathi kunciphisa ukusetshenziswa kwezinto. Lokhu kungabonakala nge-geometry elungiselelwe eqinisekisa ukusatshalaliswa kokucindezeleka okufanayo futhi kuvumela ukusetshenziswa okugcwele kwamandla aphezulu okucindezela nokugoba e-granite. Isibonelo, ukwamukela umklamo we-cross-section oguquguqukayo, lapho i-beam inezingxenye ezinkulu ezindaweni ezinesikhathi esiphezulu sokugoba kanye nezingxenye ezincane lapho ukucindezeleka kuphansi khona, kunganciphisa ngempumelelo isisindo sonke ngenkathi kugcinwa ubuqotho besakhiwo.
Amathuluzi esimanje okuhlaziya izinto ezilinganiselwe (i-FEA) manje enza kube nokwenzeka ukulingisa amajiyometri ahlukahlukene anqamula izigaba kanye nezimo zokulayisha ngokunemba okuphawulekayo. Ngokusebenzisa ukwenziwa ngcono kwezinombolo, onjiniyela bangahlaziya ukuziphatha kokucindezeleka, bathole ukungasebenzi kahle ekwakhiweni kokuqala, futhi balungise amapharamitha ukuze bafinyelele isakhiwo esisebenza kahle kakhulu. Ucwaningo lukhombisile ukuthi izingxenye zomqamelo wegranite omise okwe-T noma okwebhokisi zingasabalalisa ngempumelelo imithwalo egxilile futhi zithuthukise ukuqina ngenkathi zinciphisa isisindo—inzuzo ebalulekile kokubili uhlaka lwemishini yokwakha kanye nokunemba.
Ngaphezu kokusebenza kahle kwemishini, ukuthungwa kwemvelo kwe-granite kanye nobuhle obubonakalayo nakho kuyenza ibe yinto ehlanganisa ubunjiniyela kanye nobuhle. Izinhlobo ezihlanganisiwe ezilungiselelwe kahle—njenge-geometries ehlelekile noma e-hyperbolic—azigcini nje ngokuthuthukisa ukusebenza kahle kokuthwala umthwalo kodwa futhi ziletha ukukhanga okubonakalayo okuyingqayizivele. Ekwakhiweni kwezakhiwo, lezi zinhlobo zinegalelo ekubukekeni kwesimanje ngenkathi zigcina ukunemba komshini kanye nokuzinza i-granite edume ngakho.
Ukuhlanganiswa kobuchwepheshe bokukhanda, isayensi yezinto zokwakha, kanye nokumodela kwekhompyutha kuvumela abaklami ukuthi badlule imingcele yalokho okungafezwa yi-granite njengezinto zokwakha. Njengoba ubuchwepheshe bokulingisa buthuthuka, onjiniyela bangahlola amajiyomethri angajwayelekile kanye nezakhiwo ezihlanganisiwe ezilinganisela ukusebenza kahle kwemishini, ukuzinza, kanye nokuvumelana kokubona.
Ekuphetheni, ukwenza ngcono ukuma kwe-granite beams kumelela indlela enamandla yokuthuthukisa ukusebenza kahle kwesakhiwo kanye nokusimama. Ivumela ukusetshenziswa kwezinto ezisetshenziswayo okuncishisiwe, ukulinganiswa kwamandla nesisindo okuthuthukisiwe, kanye nokusebenza okuthuthukisiwe kwesikhathi eside—konke lokhu kugcina ubuhle bemvelo be-granite. Njengoba isidingo sezakhiwo ezinembile kakhulu nezicwengisiswe kahle siqhubeka nokukhula, i-granite, enezakhiwo zayo zomzimba ezihlukile kanye nobuhle obungapheli, izohlala iyinto ebalulekile ekuthuthukisweni kwemiklamo yezakhiwo neyezimboni yesizukulwane esilandelayo.
