I-Granite, eyaziwa ngobulukhuni bayo obukhethekile, ukuqina, kanye nokukhanga kobuhle, iye yasetshenziswa kabanzi hhayi nje njengento yokuhlobisa kodwa futhi njengengxenye yesakhiwo ekunembeni nasekusetshenzisweni kwezakhiwo. Ekwakhiweni kwesakhiwo sesimanjemanje, indlela yokuthuthukisa ukusebenza kahle kwesakhiwo ngokulungiswa kokuma kwezingxenye ezihlukene zezingongolo zegwadle sekube yisihloko sokubaluleka okukhulayo, ikakhulukazi njengoba izimboni ziphishekela kokubili izakhiwo ezingasindi kanye nokusebenza kwemishini okuphakeme.
Njengenye yezinto eziyinhloko ezithwala umthwalo ezisekelweni zezakhiwo nezinembayo, idizayini ye-cross-sectional ye-granite beam ithonya ngokuqondile umthamo wayo wokuthwala umthwalo, isisindo sawo, kanye nokusetshenziswa kwezinto ezibonakalayo. Izingxenye ezinqamulayo zendabuko—njengamafomu awunxande noma anomumo ongu-I—senesikhathi eside zihlangabezana nezimfuneko eziyisisekelo zesakhiwo. Kodwa-ke, ngokuthuthuka koomakhenikha bekhompiyutha kanye nesidingo esikhulayo sokusebenza kahle, ukwenza kahle lezi zimo zezigaba ezihlukene sekubalulekile ukuze kuzuzwe ukusebenza okuphezulu ngaphandle kokusetshenziswa kwezinto ezibonakalayo okungadingekile.
Ngokombono wokumakhenikha wesakhiwo, ingxenye enqamulayo ye-granite ye-granite efanelekile kufanele inikeze ukuqina okwanele namandla kuyilapho kunciphisa ukusetshenziswa kwezinto ezibonakalayo. Lokhu kungabonakala ngejiyomethri ethuthukisiwe eqinisekisa ukusatshalaliswa kokucindezeleka okufanayo futhi ivumele ukusetshenziswa okugcwele kwamandla aphezulu e-granite okucindezela nokugoba. Isibonelo, ukwamukela idizayini eguquguqukayo ye-cross-section, lapho i-beam inezigaba ezinkulu ezindaweni zomzuzu wokugoba ophezulu kanye nezigaba ezincane lapho izingcindezi ziphansi, kunganciphisa ngempumelelo isisindo sisonke ngenkathi kugcinwa ubuqotho besakhiwo.
Amathuluzi esimanjemanje e-finite element analysis (FEA) manje enza kube nokwenzeka ukulingisa amajiyometri ahlukene ahlukene kanye nezimo zokulayisha ngokunemba okumangalisayo. Ngokulungiselela izinombolo, onjiniyela bangakwazi ukuhlaziya ukuziphatha kokucindezeleka, bahlonze ukungasebenzi edizayini yangempela, kanye namapharamitha wokushuna kahle ukuze bathole isakhiwo esisebenza kahle kakhulu. Ucwaningo luye lwabonisa ukuthi izingxenye ze-granite ezimise okwe-T noma ezimise okwebhokisi zingasabalalisa ngempumelelo imithwalo egxilile futhi zithuthukise ukuqina kuyilapho zinciphisa isisindo—inzuzo enkulu kukho kokubili uhlaka lwemishini yokwakha nokunemba.
Ngokungeziwe ekusebenzeni kwemishini, ukuthungwa kwemvelo kwe-granite nobuhle bokubuka nakho kuyenza ibe into ehlanganisa ubunjiniyela nobuhle. Amafomu athuthukisiwe ahlukene—njengamajiyometri enziwe ngendlela ehlelekile noma eye-hyperbolic—akugcini nje ngokuthuthukisa ukuthwala kahle umthwalo kodwa futhi ethula ukukhanga okuhlukile kokubuka. Ekwakhiweni kwezakhiwo, lezi zimo zifaka isandla ebuhleni besimanje ngenkathi kugcinwa ukunemba kwemishini nokuzinza igwadule elidume ngakho.
Ukuhlanganiswa koomakhenikha bobunjiniyela, isayensi yezinto zokwakha, kanye nokumodela kwekhompyutha kuvumela abaklami ukuthi baphushe imikhawulo yalokho okungafinyelelwa yi-granite njengezinto zokwakha. Njengoba ubuchwepheshe bokulingisa buthuthuka, onjiniyela bangahlola amajiyometri angajwayelekile kanye nezakhiwo eziyinhlanganisela ezilinganisa ukusebenza kahle kwemishini, ukuzinza, nokuvumelana okubonakalayo.
Sengiphetha, ukwenza ngcono ukuma kwezingxenye ezihlukene zemishayo yegwadle kumelela indlela enamandla yokuthuthukisa ukusebenza kahle kwesakhiwo kanye nokusimama. Ivumela ukusetshenziswa kwempahla encishisiwe, izilinganiso ezithuthukisiwe zamandla nesisindo, nokusebenza okuthuthukisiwe kwesikhathi eside—konke kuyilapho kugcinwa ubuhle bemvelo begwadle. Njengoba isidingo sokunemba okuphezulu kanye nezakhiwo ezicwengisiswe ngobuhle siqhubeka sikhula, igwalagwala, elinezinto zalo ezibonakalayo ezingavamile kanye nobuhle obungaphelelwa yisikhathi, lizohlala liyinto ebalulekile ekuthuthukisweni kwemiklamo yesizukulwane esilandelayo yesakhiwo kanye nezimboni.
