Lub round bar yuav tsum yoog raws li qhov nws siv, txawm tias vim li cas rau nws lub hom phiaj yuav yog lwm qhov. Nrog rau lwm cov ntaub ntawv, conformability tsis yog qhov kev txhawj xeeb tseem ceeb, yog li lwm hom tuav nrog cov duab sib txawv tuaj yeem ua rau nkig ntau dua vim tias lawv muaj qhov sib txawv ntawm cov hlau nyob hauv lawv qhov ntev, yog li puag ncig yog suav tias yog steel bar uas muaj kev ua tau zoo tshaj plaws.
Niaj hnub no, qhov xav tau ntawm cov khoom siv no yog qhov ruaj khov, tshwj xeeb tshaj yog muab tso rau hauv qhov chaw muaj kev ua haujlwm seismic tseem ceeb. Rau lub hom phiaj no, cov tuav yuav tsum yoog raws li kev tswj hwm lub hom phiaj. Tsis tas li ntawd xwb, lawv yuav tsum nyob rau hauv tib txoj kev muaj peev xwm rov qab mus rau qhov qub daim ntawv lawv muaj.
