1. Lub tensile, compressive thiab shear lub zog ntawm cov hlau yog qhov siab, thiab cov qauv ntawm cov qauv steel cov tswv cuab yog me me thiab qhov hnyav tuag yog lub teeb. Feem ntau, qhov hnyav ntawm cov vaj tse siab tshaj plaws yog li 1.5-2.0t / m2, thiab cov qauv hlau ntawm cov tsev siab siab feem ntau qis dua 1 T / m2, thiab txawm tias qee lub tsev ua haujlwm tsuas yog 0.5-0.6t. /m2. Lub teeb yuag ntawm cov qauv tuaj yeem txo tus nqi ntawm kev thauj mus los thiab nqa, thiab kev thauj khoom ntawm lub hauv paus tuaj yeem txo tus nqi ntawm lub hauv paus, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam tsis zoo ntawm thaj av, nws cov yam ntxwv tseem ceeb dua.
2. Cov qauv hlau muaj qhov zoo ductility thiab zoo seismic kev ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv siab siv av qeeg, kev siv cov qauv hlau yog qhov zoo dua, cov ductility ntawm cov pob zeb ua kom muaj zog yog lav tias qhov kev ntxhov siab ntawm cov qauv tsis siab dhau, thiab cov ductility. ntawm steel qauv yog ua kom ib co tswv cuab rau hauv yas.
Hauv cheeb tsam av qeeg loj heev, muaj kev tiv thaiv kev tiv thaiv ntawm cov tsev siab siab, yog tias qhov hnyav ntawm ib nrab, sib npaug los txo seismic fortification degree. Siv Beijing 8 ° seismic crack tiv thaiv degree ua piv txwv, cov tsev nruab nrab qhov siab siv cov qauv steel hnyav txo los ntawm 1/3, av qeeg tuaj yeem txo los ntawm 30-40%, qhov hnyav ntawm ib cheeb tsam ntawm lub hauv paus kuj tuaj yeem txo. los ntawm ntau tshaj 25%.
3. Lub cheeb tsam nyob ntawm tus qauv (los yog hu ua tus qauv dav hlau ntom) yog me me, uas ua rau kom cov cheeb tsam siv tau. Steel qauv tsev steel qauv occupies tsuas yog 28% ntawm tib hom reinforced pob zeb tsev cheeb tsam. Kev siv cov qauv steel tuaj yeem ua rau thaj tsam siv 4% -8%, uas yog qhov ua tau kom nce kev siv tus nqi ntawm lub tsev, nce kev lag luam nyiaj txiag. Piv txwv li, Changfugong Center nyob rau hauv Beijing (26-zaj dab neeg ntshiab steel thav duab system) txais steel qauv, thiab seem ntawm steel kem tsuas yog 450 * 450mm, thaum lub sij hawm tus naj npawb ntawm cov plag tsev thiab kem network ntawm zoo xws li cov reinforced pob zeb qauv, seem ntawm kem yog hais txog 900 * 900mm. Yog hais tias raws li qhov nce hauv cheeb tsam siv ntawm 4% kev suav, rau ib lub tsev ntawm 50,000 square metres, sib npaug ntawm qhov nce ntawm thaj tsam ntawm 200 square meters, nws tus nqi yog qhov tseem ceeb heev.
