Lub preloading ntawm daim ntawv qhia linear yog ua ntej thauj cov pob steel, thiab siv qhov tsis zoo ntawm lub pob steel thiab lub pob channel rau preload, uas tuaj yeem txhim kho qhov nruj ntawm cov kab ntawv qhia thiab tshem tawm qhov sib txawv. Raws li qhov loj ntawm preload, nws tuaj yeem muab faib ua ntau qib preloading. Lub siab ua ntej sib txawv ntawm kev tshem tawm mus rau 0.13C. Tus nqi ntawm C yog dynamic rated load.
Thaum lub sijhawm xaiv, koj tuaj yeem rov qab mus rau cov kauj ruam dhau los rau kev xaiv rov qab thiab rov teeb tsa txhua lub sijhawm raws li cov txiaj ntsig suav. Thaum xam cov load ntau dua ntawm cov zawv zawg thaiv, nws yuav tsum tau lees paub tias qhov kev nyab xeeb zoo li qub ntawm cov kev xaiv kab qhia kev tsheb nqaj hlau yuav tsum tshaj tus nqi teev nyob rau hauv cov lus pom zoo. Yog hais tias qhov rigidity ntawm qhov kev xaiv ntawm cov kab ntawv qhia kev tsheb ciav hlau tsis txaus, lub siab ua ntej tuaj yeem nce ntxiv, qhov kev xaiv loj tuaj yeem nce ntxiv lossis cov zawv zawg zawv zawg tuaj yeem nce ntxiv los txhim kho qhov rigidity.
Static kev ruaj ntseg yam yog txhais raws li qhov piv ntawm static rated load rau ua hauj lwm load. Nws yog ib qho tsim nyog hais tias cov kab qhia kev sib txuas nrog ob kab ntawm Goethe hom qauv tuaj yeem tiv taus lub zog thiab lub sijhawm nyob hauv txhua qhov kev qhia. Nws yog dav siv nyob rau hauv lub teeb load los yog nruab nrab load daim ntaub ntawv, tshwj xeeb tshaj yog thaum lub lateral quab yuam load yog loj. Thaum cov kab ntawv qhia kev tsheb ciav hlau nrog plaub kab ncig arc qauv muaj ntau daim ntawv thov nyob rau hauv hnyav load los yog hnyav load, lub voj arc hom muaj peev xwm nqus tau qhov sib dhos deg yuam kev.
