Hlau yog cov hlau siv los tsim cov qauv loj, xws li txuas hniav, cov tsev lag luam thiab cov tsev nyob. Cov qauv hlau feem ntau muab faib ua peb hom: cov qauv steel feem ntau muab faib ua peb hom: cov qauv steel, cov qauv hlau bolted thiab lub teeb steel qauv. Piv nrog rau cov vaj tse pob zeb, cov tsev muaj ntau yam zoo.
1. Cov hlau yog cov hlau ruaj khov heev. Nws tuaj yeem tiv taus ntau sab nraud. Yog li ntawd, steel qauv yog aseismic, thaum cov qauv pob zeb yog nkig. Qhob yog tsawg resistant dua hlau.
2. Piv nrog cov qauv pob zeb, cov qauv steel muaj peev xwm zoo, tab sis cov kabmob muaj peev xwm ntawm cov qauv pob zeb yog tsawg heev.
3. Hlau yog cov hlau tensile. Nws muaj lub zog siab rau qhov hnyav piv. Cov qauv hlau yog 60 feem pua sib dua li pob zeb.
4. steel qauv kev ua haujlwm tuaj yeem tsim tsis muaj lub hauv paus, tab sis nws tsis haum rau cov pob zeb hnyav.
5. Cov qauv steel yog yooj yim rau erect, yog li cov txheej txheem kev tsim kho sai dua. Qhov no pab ua kom tiav qhov project sai dua. Ntawm qhov tod tes, kev tsim vaj tsev yog siv sijhawm ntev heev. 5. Cov qauv steel yog yooj yim rau erect, yog li cov txheej txheem kev tsim kho sai dua. Qhov no pab ua kom tiav qhov project sai dua.

6. Muab piv nrog cov pob zeb uas muaj cov khoom pov tseg me me, nws muaj cov khoom pov tseg zoo los ua cov qauv hlau zoo dua.
7. Steel qauv ua yog ib qho yooj yim los tsim thiab loj ntau lawm. Lawv tau siv dav thiab yooj yim rau kev sib sau, disassemble thiab hloov.
8. Lwm qhov zoo ntawm. Cov qauv hlau txhais tau hais tias lawv tuaj yeem tsim khoom ntawm qhov chaw los ntawm cov tuam txhab steel qauv thiab tom qab ntawd sib sau ua ke ntawm qhov chaw.
9. Cov qauv hlau yog cov kev xaiv ib puag ncig zoo vim tias lawv yooj yim rau rov ua dua.
