【摘要】 地震波谱分析表明 ,地震区建筑结构用钢受震时的主要失效形式是高应力低周疲劳损伤和断裂。提高建筑结构钢的抗震性 ,应在保证钢材具有较高强度的同时 ,提供其塑性和韧性。低碳微合金铁素体晶粒超细化钢、双相钢和低合金相变诱发塑性钢都具有良好的抗震性。本文对钢的抗震性、显微组织和成分设计进行了简要阐述。更多还原

【Abstract】 The earthquake spectrums analysis indicated that the failures of building structural steels at seismic areas are created of high stress strain and low cycle fatigue.Therefor,the mechanical properties of anti seismic building structural steels must be fairly high strength with good ductility and toughness.The low carbon micro alloyed ultra fine grained steel,low carbon duplex steels and low alloyed transformation induced plasticity(TRIP) steel has good anti seismic property.更多还原
