CARBON STEEL H BEAM Q690 HN tus tswv cuab tsis yog tsuas yog raug rau axial rog tab sis kuj yog lub sijhawm khoov los ntawm seismic loading. Yog li ntawd, nws cov lus teb cyclic yuav tsum yog qhov nyuaj thiab tseem ceeb heev rau kev tsim seismic. Cov kev tshawb fawb yav dhau los tau pom tias steel beam-kem nyob rau hauv seismic loading tej zaum yuav muaj zog thiab nruj deterioration uas tau tsav los ntawm lub zos buckling los yog low-cycle fatigue puas, uas ua rau cov kev hloov zoo kawg li nyob rau hauv lawv tus cwj pwm hysteretic.
