Cov hlau txuasyog ib yam khoom tseem ceeb uas siv dav hauv kev tsim kho vaj tse thiab kev tsim kho vaj tse, thiab nws lub zog, kev tawv thiab kev hloov pauv tsis tau ua rau nws ua lub luag haujlwm tseem ceeb hauv kev tsim vaj tsev niaj hnub. Ua ntej tshaj plaws, lub zog thiab kev tawv ntawm rebar yog pom tseeb hauv nws cov khoom zoo heev tensile thiab compressive. Cov khoom no tuaj yeem tiv taus cov khoom hnyav yam tsis tawg thiab hloov kho rau ntau yam kev ua haujlwm nyuaj. Hauv kev tsim kho, rebar feem ntau siv ua ke nrog cov pob zeb ua ke los tsim cov khoom sib xyaw uas tseem ceebtxhim kho qhov muaj peev xwm thauj khoomthiab kev ua tau zoo ntawm kev tiv thaiv av qeeg ntawm lub tsev, yog li ua kom muaj kev nyab xeeb thiab kev ruaj khov ntawm lub tsev.
Qhov thib ob, qhov kev tiv thaiv kev qaug zog ntawm rebar kuj yog ib qho tseem ceeb ntawm nws lub zog thiab kev tawv. Cov qauv tsev raug rau cov khoom thauj rov ua dua thiab kev cuam tshuam ib puag ncig thaum siv, thiab rebar tuaj yeem tswj nws cov khoom siv kho tshuab rau lub sijhawm ntev ntawm kev siv, txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm cov qauv kev qaug zog. Tus cwj pwm no yog qhov tseem ceeb tshwj xeeb hauv cov haujlwm tseem ceeb xws liCov choj, cov tsev siabthiab cov chaw pej xeem loj, ua kom muaj kev ruaj khov mus sij hawm ntev ntawm cov chaw no.
Hauv kev xaus lus, rebar tau dhau los ua cov khoom siv tseem ceeb hauv cov haujlwm tsim kho vim nws lub zog zoo heev thiab kev tawv thiab tsis hloov pauv tau. Nrog rau kev txhim kho ntawm kev siv tshuab engineering, kev siv rebar kuj tseem yuav txuas ntxiv mus tob zuj zus, txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm cov tsev. Hauvkev tsim kho yav tom ntej, rebar yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev nce qib thiab kev tsim kho tshiab ntawm kev lag luam.
Tham txog qhov tsis tuaj yeem hloov pauv ntawm rebar, nws feem ntau yog pom tseeb hauv ntau yam. Ua ntej tshaj plaws, cov txheej txheem tsim khoom thiab cov yam ntxwv ntawm cov khoom siv ntawm rebar ua rau nws qhov zoo hauv tus nqi thiab kev ua tau zoo nyuaj rau hloov los ntawm lwm cov ntaub ntawv. Txawm hais tias qee cov ntaub ntawv sib xyaw tshiab tau ua tiav hauv qee yam khoom, rebar tseem yog qhov kev xaiv pheej yig thiab siv tau zoo hauv kev tsim kho loj. Qhov thib ob, hais txog lub peev xwm dais, kev tiv thaiv kev poob siab thiab kev yooj yim ntawm kev tsim kho, kev ua tau zoo ntawm rebar tsis muaj qhov sib piv los ntawm lwm cov ntaub ntawv tam sim no. Qhov no ua rau nws yog lub hauv paus ntawm kev lag luam kev tsim kho niaj hnub.
