Nyob rau hauv seismic zones, h {- Beams outperform ob sab ua hauv plaub qhov tseem ceeb:
Ductility thiab lub zog dissipation:
Steel lub siab ua kom tiav h - Beams rau deform tseem ceeb yam tsis muaj kev ua tsis tiav, nqus seismic lub zog zoo. Ib qho ib txwm s355 h {3} Tsov txaij 20% ntawm nws qhov qub ua ntej tawg, piv rau cov qhob ua tsis tiav ntawm tsuas yog 0.1% hom. This ductility reduces the risk of catastrophic collapse, as seen in the 2011 Tohoku earthquake, where H-beam-framed buildings in Japan maintained structural integrity better than concrete counterparts.
Lub zog - rau - Qhov hnyav nyhav:
H - Beams yog sib dua dua li cov pob zeb rau tib lub peev xwm hauv av hauv av. Lub pob zeb ua vaj tse ntawm sib npaug lub zog rau HW 300 × 300 nqaj kev hnyav 300% ntau dua, nce seismic thauj khoom ntawm lub hauv paus. Qhov hnyav dua tseem yooj yim dua cov txheej txheem uas twb muaj lawm nrog h {{Beam braces, raws li pom hauv san francisco qhov seismic cov seismic ntawm cov vaj tse keeb kwm.
Kev sib txuas hloov:
Bolted lossis welded h - nqaj pob qij txha tso cai rau kev tswj hwm kev txav thaum lub sij hawm seismic. Lub sijhawm - Tsis txhob sib txuas hauv cov pob qij txha feem ntau tawg thiab poob} bearing muaj peev xwm. Kev tshawb fawb pom h {{6} tshiav cov qauv kev ua haujlwm 30-50% tsawg dua kev puas tsuaj nyob rau hauv av qeeg.
Kho sai thiab rov qab:
Puas h {- Beams tuaj yeem hloov lossis kho kom nrawm dua li ua kom tawg, qhov tseem ceeb rau kev rov qab los. Lawv qhov rov qab ua dua tshiab kuj tseem txo cov khib nyiab, raws li 90% ntawm seismic- Beams tuaj yeem siv dua lossis rov ua dua tshiab- Resilience cov hom phiaj.
