Intshayelelo
Kummandla wobunjineli bolwakhiwo, ukufuna izinto kunye noyilo olwandisa ukusebenza kunye nokuqina kwezinto zokwakha kuyaqhubeka. Uphononongo lwakutsha nje lukhanyise ukusebenza koxinzelelo lwe-axial lwetyhubhu enesikhumba esiphindwe kabini (CFDST) eyomelezwe nge-carbon fibre eyomeleziweyo yepolymer (CFRP). Le ndlela entsha ibaluleke kakhulu kwiinkampani ezifana ne-Tianjin Reliance Steel, ekhethekileyo ekuvelisweni kweetyhubhu zetsimbi zesikwere kunye ne-rectangular, kuquka i-SHS (i-Square Hollow Sections) kunye ne-RHS (i-Rectangular Hollow Sections). Eli nqaku lijonge kwiziphumo zophononongo, iimpembelelo kushishino lokwakha, kunye nendlela iTianjin Reliance Steel ebekwe ngayo ukuhlangabezana neemfuno eziguquguqukayo zezicelo zesakhiwo.
Ukuqonda iMibhobho eneLusu eliBibini ezaliswe ngeConcrete (CFDST)
Iibhubhu eziphindwe kabini zekhonkrithi ziyi-composite yesakhiwo esidibanisa inzuzo yentsimbi kunye nekhonkrithi. Ityhubhu yentsimbi yangaphandle inika ukuvalelwa kwisiseko sekhonkrithi, iphucula amandla ayo oxinzelelo kunye ne-ductility. Olu yilo lunenzuzo ngakumbi kwiindawo ezithandwa yinyikima, apho izakhiwo kufuneka zimelane namandla asecaleni abalulekileyo. Uphononongo kugxininiso luvavanya iikholamu ezili-15 zeCFDST, nganye inezikim zokuqinisa iCFRP ezahlukeneyo, ukuvavanya ukusebenza kwazo kwe-axial compression.
Indima yeCFRP kuQiniso lweZakhiwo
I-carbon fiber reinforced polymer (CFRP) yimathiriyeli ekhaphukhaphu, eyomelele kakhulu ethe yafumana ukuthandwa kwizicelo zesakhiwo ngenxa yeempawu zayo ezigqwesileyo zoomatshini kunye nokuxhathisa ukuthotywa kokusingqongileyo. Ngokudibanisa iCFRP kuyilo lweekholamu zeCFDST, iinjineli zinokuphucula ngokubonakalayo umthamo wokuthwala umthwalo kunye nokusebenza ngokubanzi kwezi zakhiwo. Uphononongo luphanda izikimu ezahlukeneyo zokuqinisa, ukuhlalutya ukuba ulungelelwaniso olwahlukileyo lweCFRP lunokwandisa njani ukusebenza koxinzelelo lwe-axial kwiikholamu.
Iziphumo eziphambili zolu phando
Uphando luqaqambisa izinto ezininzi ezifunyanisiweyo ezibalulekileyo malunga nokusebenza koxinzelelo lwe-axial ye-CFRP-yomelezwe kwiikholamu ze-CFDST:
- Umthamo wokuthwala imithwalo eyongezelelweyo: Ukufakwa kwe-CFRP ukuqiniswa kwandisa kakhulu umthamo wokuthwala umthwalo weekholomu zeCFDST. Uphononongo lubonisa ukuba izikimu ezithile zokuqinisa zingakhokelela ekuphuculeni okuphawulekayo ekusebenzeni xa kuthelekiswa neetyhubhu zendabuko ezizaliswe ngekhonkrithi.
- I-Ductility kunye ne-Energy Absorption: Ukomelezwa kweCFRP akugcini nje ukwandisa amandla kodwa kuphucula i-ductility yeentsika. Olu phawu lubalulekile kwizicelo zenyikima, apho izakhiwo kufuneka zifunxe kwaye zichithe amandla ngexesha lenyikima.
- Iindlela zokungaphumeleli: Uphononongo luchonga iindlela ezahlukeneyo zokungaphumeleli kwiikholamu zeCFDST eziqiniswe yiCFRP, zibonelela ngeembono ezixabisekileyo malunga nendlela ezi zakhiwo ziziphatha ngayo phantsi kwemithwalo ye-axial. Ukuqonda ezi ndlela zokungaphumeleli kubalulekile ekuyileni izakhiwo ezikhuselekileyo nezomelela ngakumbi.
- IiSkimu zoQinisekiso eziLungileyo: Ngokuthelekisa ulungelelwaniso lokuqiniswa kweCFRP olwahlukeneyo, uphando luchonga izikimu ezizezona zandisa ukusebenza ngelixa kuncitshiswa ukusetyenziswa kwezinto. Oku kufunyanisiweyo kubaluleke ngakumbi kwiindlela zokwakha ezingabizi kakhulu.
Iimpembelelo kuShishino loKwakha
Iziphumo zolu phononongo zineempembelelo ezibalulekileyo kushishino lokwakha, ngakumbi ekuyilweni nasekuphunyezweni kwezinto zesakhiwo kwizakhiwo eziphakamileyo, iibhulorho kunye nezinye iziseko ezingundoqo. Ukusebenza okwandisiweyo kweekholamu zeCFDST eziqiniswe yiCFRP kunokukhokelela kwizakhiwo ezikhuselekileyo, ezomelela ngakumbi ezixhotyiswe ngcono ukumelana nemingeni ebangelwa ziintlekele zendalo kunye nemithwalo enzima.
Ngaphaya koko, ukukwazi ukwenza izikimu zokuqinisa zivumela iinjineli ukuba zenze izakhiwo ezingenamandla kuphela kodwa zinoqoqosho ngakumbi. Oku kubaluleke ngakumbi kwixesha apho uzinzo kunye nokusebenza kakuhle kweendleko kubaluleke kakhulu kwimisebenzi yokwakha.
