Iko kushandiswa kweFiber Reinforced Polymer (FRP) bhiriji decks kuri kushandura mamiriro ekuvakwa kwebhiriji.
Mabhiriji echinyakare akagadzirwa nekongiri yakasimbiswa uye zvivakwa zvesimbi zvakagara zvichitambudzwa ne ngura uye kuparara kwekongiri, kwete chete kupfupisa hupenyu hwemabhiriji asiwo zvinogona kutungamira kune njodzi dzakakomba dzekuchengetedza. Iyi nyaya inonyanya kuoma munzvimbo dzemahombekombe dzine high chloride ion concentration, uko kuora kwemabhiriji idambudziko rakakura. Nekudaro, kuvandudza kusimba kwemabhiriji decks rave dambudziko guru muinjiniya yemabhiriji.
FRP inoonekwa sechinhu chakanakira kusimudzira kusimba kwemabhiriji nekuda kwekushomeka kwayo kwegora. FRP mabhiriji masisitimu anowanzo kuuya mumhando mbiri: ese-FRP zvimiro uye FRP-kongiri inoumbwa dhizaini, ine akasiyana-siyana emuchinjika-chikamu mafomu. Kuenzaniswa neyekare yakasimbiswa kongiri decks, FRP dhizaini inopa akawanda mabhenefiti: iwo akagadzirwa kare mumafekitori, akareruka, uye anokurumidza kuisa; ivo vanonyatso ramba ngura kubva mumunyu wechando, mvura yegungwa, uye chloride ions, kuderedza mari yekugadzirisa; uremu hwavo huremu hunoderedza mutoro pazvivakwa zvinotsigira; sechinhu elastic, vanogona kudzokera kumamiriro avo epakutanga pasi penguva nenguva. uye vane kuita kwakanaka kwekuneta. Mumashandisirwo anoshanda, FRP dhizaini masisitimu haango shandiswa mukuvaka mabhiriji matsva chete asi akakodzerawo kugadziridza mabhiriji ekare, kutsiva echinyakare kongiri decks. Izvi hazvingodzikisi huremu hwedeki asi zvakare zvinowedzera kutakura-kuremerwa simba uye kushora kwebhiriji.
Iwo anotakura-mutoro maitiro eFRP bhiriji decks anonyanya kusanganisira nguva dzekukotama, mauto ekugera, uye kumanikidzwa kwenzvimbo. Yese-FRP dhizaini kazhinji ine yekumusoro uye yakaderera FRP matehwe uye dandemutande, iine ganda repamusoro rinotakura compression, rezasi ganda rinotakura kushushikana, uye dandemutande rinonyanya kurwisa shear masimba uchibatanidza ekumusoro neazasi matehwe. MuFRP-kongiri / huni inoumbwa dhizaini, kongiri kana huni inoiswa munzvimbo yekumanikidza, nepo FRP ichinyanya kutakura kushushikana. Masimba ekuveura pakati pavo anotamiswa kuburikidza neshear zvibatanidza kana nzira dzekunamatira. Pasi pemitoro yenzvimbo, FRP decks zvakare inosangana nekukotama, kubaya shear, kana kupwanya masimba; asymmetric mitoro inoburitsawo torsion pachikamu. Sezvo FRP iri anisotropic uye isiri-homogeneous zvinhu, ma mechanical performance parameters inoda kutariswa kuburikidza nelaminate dhizaini, ichiita kuti dhizaini yeFRP decks ive yakaoma, inoda kubatana kwepedyo pakati pevagadziri uye nyanzvi FRP vatengesi.
