Lorem Ipsum ni inyandiko yuzuye yinganda zo gucapa no kwandika. Lorm Ipsum yabaye inganda zisanzwe za dummy inyandiko yafashe ikigali cyubwoko arayitondagura kugirango akore igitabo cyikitegererezo. Lorem Ipsum ni inyandiko yuzuye yo gucapa no kwandika Lorem Ipsum ni inyandiko yuzuye yerekana inganda zo gucapa no kwandika imashini.
Ikoreshwa rya Fibre Reinforced Polymer (FRP) ikiraro kirahindura imiterere yo kubaka ikiraro.
Ibiraro gakondo bikozwe mu byuma bikozwe mu byuma no mu byuma bimaze igihe kinini byibasiwe n’ingese no kwangirika kwa beto, ntibigabanya gusa igihe cy’ibiraro gusa ahubwo bishobora no guteza umutekano muke. Iki kibazo kirakabije cyane mubice byinyanja hamwe na chloride ion nyinshi, aho kwangirika kwikiraro nikibazo gikomeye. Rero, kuzamura uburebure bwikiraro cyabaye ikibazo gikomeye mubwubatsi bwikiraro.
FRP ifatwa nkibikoresho byiza byongera uburebure bwikiraro kubera kwihanganira ruswa. Sisitemu yikiraro cya FRP mubusanzwe iza muburyo bubiri: ibyubatswe byose-FRP hamwe na FRP-beto igizwe, hamwe nuburyo butandukanye bwambukiranya. Ugereranije nu gakondo gakondo gishimangiwe, beto ya FRP itanga inyungu nyinshi: zakozwe munganda, zoroheje, kandi byihuse gushiraho; barwanya neza ruswa ituruka ku munyu wa barafu, amazi yo mu nyanja, na chloride ion, bikagabanya amafaranga yo kubungabunga; uburemere bwabo bworoshye bugabanya umutwaro kubintu byubaka; nkibikoresho byoroshye, barashobora gusubira muburyo bwabo bwambere mugihe kirenze urugero; kandi bafite imikorere myiza yumunaniro. Mubikorwa bifatika, sisitemu ya palike ya FRP ntabwo ikoreshwa gusa mubwubatsi bushya bwikiraro ahubwo irakenewe no kuvugurura ibiraro bishaje, gusimbuza amabati gakondo. Ibi ntibigabanya uburemere bwikibanza gusa ahubwo binongerera ubushobozi bwo kwikorera imitwaro hamwe no kwangirika kwikiraro.
Ibiranga imitwaro biranga ikiraro cya FRP ahanini birimo ibihe byo kunama, imbaraga zo gukata, hamwe nigitutu cyaho. Ikibanza cyose-FRP mubusanzwe kigizwe nimpu zo hejuru na hepfo ya FRP hamwe nurubuga, hamwe nuruhu rwo hejuru rufite compression, uruhu rwo hepfo rufite impagarara, nurubuga rwibanze cyane cyane imbaraga zogosha mugihe uhuza uruhu rwo hejuru no hepfo. Muri FRP-beto / ibiti bigizwe nibiti, beto cyangwa ibiti bishyirwa muri compression, mugihe FRP yihanganira cyane. Imbaraga zogosha hagati yazo zihererekanwa binyuze mumashanyarazi cyangwa uburyo bwo gufatira hamwe. Munsi yimitwaro yaho, imitambiko ya FRP nayo ifite uburambe, kunama, cyangwa gukubita imbaraga; imizigo idasanzwe nayo itanga torsion kumurongo. Kubera ko FRP ari anisotropique kandi idahuje igitsina, ibipimo byimikorere yubukanishi bigomba kugenwa hifashishijwe igishushanyo mbonera, bigatuma igishushanyo mbonera cya FRP kigorana, bisaba ubufatanye bwa hafi hagati yabashushanya nabatanga FRP babigize umwuga.
Hariho ubwoko bwinshi bwikiraro cya FRP, gishobora gushyirwa mubice bitanu byingenzi: Ubwoko A ni paneli ya sandwich ya FRP; Ubwoko B bukusanyirijwe hamwe ibisate bya profili ya FRP; Ubwoko C ni urupapuro rwimbere rwa FRP hamwe nibisobanuro byibanze byimbere; Ubwoko D ni FRP-beto / imbaho yibiti; na Ubwoko E ni byose-FRP superstructures. Ubu bwoko bwa kiraro cya FRP bwakoreshejwe mumishinga myinshi yubuhanga.
Ibyiza bya sisitemu yikiraro cya FRP harimo uburemere bwabyo, kurwanya ruswa ikomeye, kwishyiriraho byihuse, imbaraga zubatswe hejuru, hamwe nigiciro gito cyo kubungabunga. By'umwihariko mubijyanye n'uburemere, igorofa ya kiraro ya FRP iroroshye 10% kugeza kuri 20% ugereranije na beto gakondo ya beto ikomejwe, bivuze ko ishobora kongera ubushobozi bwo kwikorera imitwaro no kuramba kwikiraro. Byongeye kandi, kubera kurwanya ruswa ya FRP, amagorofa akora neza cyane mu guhangana n’ibibazo by’urubura, urubura, cyangwa amazi y’umunyu bikoreshwa mu gushushanya mu turere dukonje, bikaba biteganijwe ko uzamara imyaka 75 kugeza ku 100. Byongeye kandi, kubera imbaraga nyinshi zibikoresho bya FRP, ibyifuzo byabo byo gushushanya akenshi birakaze kuruta ibyibikoresho gakondo, ariko amakuru yukuri yikizamini yerekana ko imikorere yikiraro cya kiraro cya FRP irenze kure ibisabwa byihariye, bigatuma habaho umutekano muke.
Nubwo bimeze bityo ariko, hari ibibi byugarije ikiraro cya FRP, nkigiciro kinini cyibikoresho fatizo, na buri kiraro gisaba igishushanyo mbonera. Nkuko tekinoroji ya FRP ari shyashya, bivuze ko amafaranga yinyongera akenewe. Byongeye kandi, kubera itandukaniro rinini ryimiterere mumiterere yikiraro cya FRP kuri buri kiraro, ababikora bakeneye gukora ibishushanyo mbonera cyangwa guteza imbere ibikorwa byinganda kuri buri mushinga, biganisha ku musaruro muke. Nubwo hari ibibazo, ishyirwa mubikorwa byikiraro cya FRP mubuhanga bwikiraro biracyerekana iterambere ryagutse.
