极低屈服点钢低周疲劳特性
|
摘要
对100 MPa级的极低屈服点钢BLY100进行了包括模拟地震载荷的系列高应变低周疲劳试验。试验结果表明,BLY100钢板具有良好的低周疲劳性能,完全满足抗震设计用钢的需要。
Low yield point(LYP)steel used for the fabrication of energy dissipation damper were paid more and more attention.The high strain low cycle fatigue properties of BLY100 were studied by series of test including simulated earthquake loading.The results show that BLY100 steel plates have excellent low cycle propertyes,which meet the requirement for steel used to earthquake resistant.
