Cov pab pawg ua haujlwm tau saib xyuas ntau dua rau cov kev xaiv ntxiv rau hauv cov pob zeb uas raug dej, ntsev, lossis cov tshuaj siv tshuaj. Fiberglass reinforcement bar muab ib qho kev xaiv nonmetallic ua los ntawm iav fibers tuav nyob rau hauv ib tug resin matrix. Nws ribbed sab nrauv yog tsim los koom nrog cov pob zeb nyob ib puag ncig, thaum lub tsev qis qis hloov pauv li cas cov pob khoom thauj thiab muab tso rau ntawm qhov chaw.
Kev txiav txim siab yuav tsum pib nrog tus qauv tsim, tsis yog kev hloov khoom siv yooj yim. Tus kws ua haujlwm yuav tsum paub meej tias txoj kab uas hla, qhov sib nrug, npog, ncej puab lossis kev tsim kho, thiab cov kev txwv uas siv rau kev khoov lossis kev txiav. Cov kev qhia tshwj xeeb yuav tsum tau txheeb xyuas daim ntawv lees paub cov khoom lag luam thiab cov ntaub ntawv tshuaj xyuas uas xav tau thaum xa khoom.
Kev npaj txuas ntxiv dhau ntawm engineering. Cov pab pawg yuav khoom yuav tsum tau txiav ntev, kom muaj nuj nqis, xim lossis cov qhab nia, cov txheej txheem ntim khoom, thiab kev xa khoom raws qib. Cov thawj coj ntawm qhov chaw yuav tsum tau cia chaw tiaj tus, tiv thaiv cov chaw txiav, thiab ib txoj hauv kev los ua kom txhua pab pawg muab cais tawm. Cov kauj ruam no txo cov kev ua yuam kev ua ntej pib ua haujlwm.
Cov khoom siv yuav raug txiav txim siab rau cov dej ua haujlwm, cov qauv hydraulic, cov khoom siv hluav taws xob, cov chaw ua dej, thiab lwm yam corrosion- qhov chaw rhiab heev. Txhua qhov kev siv tseem nyob ntawm qhov kev pom zoo tsim thiab cov txheej txheem ntawm qhov chaw. Kev sib koom ua ke thaum ntxov ntawm tus tsim qauv, tus neeg xa khoom, thiab tus neeg tsim khoom yuav pab cov kev xaiv qhov txhawb nqa tuaj txog hauv daim ntawv uas tuaj yeem kuaj xyuas thiab muab tso rau yam tsis muaj qhov hloov pauv kawg - feeb.
