Laminated glulam yog cov khoom siv ntoo tshiab uas tsim los teb rau cov kev hloov pauv ntawm cov peev txheej hauv hav zoov thiab kev txhim kho cov qauv tsev niaj hnub. Cov khoom no tsis tsuas yog khaws qee yam ntawm cov yam ntxwv zoo ntawm cov khoom ntuj ntoo sawn, tab sis kuj kov yeej cov khoom tsis sib xws thiab qhov loj ntawm cov ntoo ntuj. Kev txwv, ziab thiab nyuaj hauv kev kho corrosion.
Vim yog qhov me me elastic modulus ntawm ntoo nws tus kheej thiab tsis zoo pib flexural rigidity ntawm cov ntoo beam-kem pob qij txha, cov ntshiab glulam thav duab system feem ntau muaj tsis txaus lateral tsis kam, yog li cov ntoo ncej txhawb nqa qauv thiab ntoo ncej shear phab ntsa qauv yog feem ntau yog siv.
Lub zog thiab kav ntev ntawm cov qauv glulam nyob ntawm qhov loj ntawm cov kua nplaum zoo. Yuav tsum tsim raws li kev cai tshwj xeeb. Yog li ntawd, hauv kev tsim thiab tsim khoom, cov kev cai tshwj xeeb yuav tsum tau muab tso rau pem hauv ntej rau kev xaiv cov kua nplaum, cov qauv splicing ntawm ntoo thiab cov txheej txheem ntawm gluing.
