Lub pob zeb-filled steel tube qauv rau cov cuab yeej siv tshuab yog ib hom tshiab ntawm cov qauv sib xyaw tsim los ntawm kev sau cov raj steel nrog pob zeb. Vim hais tias cov pob zeb uas muaj steel tube qauv rau cov qauv siv tshuab tuaj yeem siv tau qhov zoo ntawm ob cov ntaub ntawv ntawm cov hlau thiab pob zeb, nws kuj kov yeej cov kev tsis txaus siab uas cov qauv steel tube yog qhov yooj yim rau hauv zos buckling.
Nyob rau hauv xyoo tas los no, nrog rau kev sib sib zog nqus ntawm kev tshawb fawb theoretical thiab qhov tshwm sim ntawm kev tsim kho tshiab, kev siv engineering tau nce zuj zus. Lub pob zeb-filled steel tube qauv tuaj yeem muab faib ua lub kaum pob zeb-filled steel tube qauv, pob zeb-filled steel raj qauv thiab polygonal qhob-filled steel raj qauv raws li cov ntawv sib txawv. Ntawm lawv, cov pob zeb-filled steel tube qauv thiab pob zeb-filled steel raj qauv yog dav siv.
