Q690 HN CARBON STEEL H BEAM feem ntau raug xa mus rau cov uas muaj lub zog muaj zog tshaj 460 MPa. Piv nrog rau cov pa ib txwm muaj zog steels, high-strength steels muaj qhov zoo ntawm cov txiaj ntsig siab thiab tensile lub zog thiab lub teeb nws tus kheej [1]. Lub teeb nws tus kheej qhov hnyav ntawm cov qauv hlau muaj zog tuaj yeem txo qhov kev ua seismic hauv nws thiab tuaj yeem ua rau muaj kev lag luam ntau dua hauv cheeb tsam seismic. Raws li cov txiaj ntsig zoo no, cov hlau muaj zog muaj zog nrog cov txiaj ntsig zoo ntawm 460 txog 690 MPa tau siv ntau dua hauv cov qauv, xws li Landmark Tower hauv Nyij Pooj, Latitude lub tsev hauv Australia thiab Sony Center hauv Tebchaws Yelemees.
