Impembelelo ye-Basalt Fiber eQinisekisiweyo kwizinto zokuSebenza kweSeismic kwiZakhiwo
1. Ukuphuculwa koBume beZakhiwo kunye nokuqina
Amandla Okuqina Okuphakamileyo: Amandla okuqina kwe imicu yebasalt inokufikelela kwi-3000-4800 MPa, iphezulu kakhulu kuneyentsimbi eqhelekileyo (malunga ne-400-600 MPa). Oku kwandisa kakhulu amandla okuqina kunye nokucheba kwezixhobo ezinqabileyo ezifana nekhonkrithi kunye ne-masonry, ukunciphisa umngcipheko wokuqhekeka phantsi kwemithwalo ye-seismic.
iModerate Elastic Modulus: Imodyuli elastiki ye imicu yebasalt (80-110 GPa) ilele phakathi kwentsimbi (200 GPa) kunye ne-carbon fiber (200-400 GPa). Oku kubonelela ukuqina okuphuculweyo ngaphandle kokubangela ukusilela okuncinci ngenxa yokuqina okugqithisileyo.
2. Ukomelezwa kokuDutywa koLwakhiwo
Ukudutyulwa okuphuculweyo: Izakhiwo zekhonkrithi zemveli zine-ductility engekho mgangathweni kwaye ziqhelene nokusilela okushwabeneyo ngexesha leenyikima. IFayibha yeBasaltI-s, njengokuqinisa, inokusasaza iintanda kunye nokulibazisa ukusasazwa kwazo, ivumela izakhiwo ukuba zingene kwi-deformation enkulu phambi kokusilela kwaye zifunxe ngakumbi amandla e-seismic.
I-Seismic Joint Reinforcement: Ukusonga okanye ukudibanisa bfrp kwiindawo ezibaluleke kakhulu ezifana ne-beam-column joints kunye neendonga zokucheba zinokuphucula amandla okucheba kunye nekhono lokuguqula, ukuthintela ukungaphumeleli ngenxa yoxinzelelo loxinzelelo.
3. Ukwandiswa koMmandla wokuNcitshiswa kwamandla
Ukutshatyalaliswa kwamandla: Ngexesha lokulayisha, BFRP izixhobo zichitha amandla ngokusebenzisa ukungqubuzana phakathi kobuso phakathi kweentsinga kunye ne-matrix, kunye ne-fiber deformation, ukunciphisa impembelelo eyonakalisayo yamandla e-seismic kwizakhiwo.
Iimpawu zokudambisa: I-basalt fiber imidibaniso inomlinganiselo othile wokudambisa, onokunciphisa ubume bokungcangcazela kwesakhiwo kunye nokunciphisa iziphumo zeresonance.
4. Ubunzima bokuNcitshiswa koLwakhiwo
Iinkcazelo Ngeempawu eziKhala: Iifayibha zebasalt inoxinano oluphantsi (malunga ne-2.6-2.8 g/cm³), isinye kwisithathu kuphela sentsimbi. Ukutshintsha inxalenye yokuqiniswa kwentsimbi kunye BFRP okanye ukuyisebenzisa njengento yokomeleza kunokunciphisa ubunzima bezakhiwo, ukunciphisa amandla angenayo i-seismic inertial. Oku kunenzuzo ngakumbi kwizakhiwo eziphakamileyo okanye ukulungiswa kwakhona kwezakhiwo zakudala.
5. Ukuchasa ukuMdla kunye noKuhlala ixesha elide
Ukuxhathisa okuPhezulu kokuMhlwa: Iifayibha zebasalt ziyakwazi ukumelana ne-asidi, i-alkali, ubushushu obuphezulu, kunye nokufuma, okubenza bafanelekele iindawo ezinobungozi ezifana neendawo ezinxweme kunye nezityalo zemichiza. Uzinzo lwabo lwexesha elide luthintela ukuthotywa kokusebenza kwenyikima ngenxa yokubola kwezinto.
Iindleko zoLondolozo oluphantsi: Xa kuthelekiswa nokuqiniswa kwensimbi yendabuko, i-BFRP ayifuni ukugcinwa rhoqo kwe-anti-corrosion, okubangelwa iindleko eziphantsi zobomi.
6. Iifomu zesicelo kunye neemeko
Ukuqiniswa kwekhonkrithi: Ukongeza i-basalt fibers eqoshiwe (umzekelo, i-BFRC) kwikhonkrithi okanye ukusebenzisa imivalo ye-BFRP ukubuyisela ukuqiniswa kwensimbi.
Ukuqiniswa koLwakhiwo: Ukudibanisa amaphepha e-BFRP okanye iipleyiti zokuqinisa imiqadi, iikholomu, iindonga, kunye namanye amacandelo, ukuphucula iindawo ezibuthathaka ze-seismic.
Izakhiwo ezidibeneyo: Ukudibanisa i-BFRP ngentsimbi okanye ikhonkrithi ukwenza iinkqubo zesakhiwo se-hybridi, amandla okulinganisa kunye ne-ductility.
7. Ukulinganiselwa
Iindleko eziphezulu: Okwangoku, ixabiso lemveliso ye BFRP iphezulu kuneyentsimbi eqhelekileyo kodwa ingaphantsi kune-carbon fiber (CFRP).
Idatha yokuSebenza kwexesha elide eliNcinane: Uphando olungakumbi luyafuneka ekomeleleni nasekudinweni kokusebenza kwe-BFRP kwixesha elide elide (ngaphezu kweminyaka engama-50).
IiKhowudi zoYilo ezingaphelelanga: Amanye amazwe akakayifaki ngokupheleleyo i-BFRP kwiikhowudi zoyilo lwenyikima, kuxhomekeke kwimifuniselo kunye namava obunjineli.
Iimeko zobuNjineli kunye noPhando
Ukulungiswa kwakhona kwenyikima ye-Post-Hanshin eJapan: BFRP yayisetyenziselwa ukubuyisela iibhulorho kunye nezakhiwo, ebonisa ukusebenza okubalulekileyo.
I-Post-Wenchuan Earthquake Reconstruction e-China: Ezinye izikolo kunye nezibhedlele zaye zahlaziywa nge-BFRP ukuphucula ukuxhathisa kwe-seismic.
Uphando loVavanyo: Uphononongo lubonisa ukuba iikholamu zekhonkrithi eziqinisiweyo ze-BFRP zinokufikelela kwi-30% -50% yokwanda kwe-ductility yokufuduswa kunye ne-20% -40% yokuphucula amandla okutshatyalaliswa kwamandla.
Ukuqukumbela
I-basalt fiber imathiriyeli eyomeleziweyo iphucula kakhulu ukusebenza kwenyikima kwezakhiwo ngokuphucula amandla, ukudubeka, kunye nomthamo wokuchitha amandla. Zifaneleke ngakumbi kwiindawo ezinobunzulu benyikima, indawo enomhlwa, okanye iimeko ezifuna uyilo olukhaphukhaphu. Ngokunciphisa iindleko kunye nokuphucula iikhowudi zokuyila, ukusetyenziswa kwe-BFRP kubunjineli benyikima kunamathemba abanzi.
