摘　　要：建筑用钢板正向高强度、高性能、大型化方向发展,780MPa级高强度抗震钢已应用于超高层大跨距建筑中,高强度钢抗震性能已成为重点解决的课题之一。从性能要求、化学成分设计、生产工艺控制及组织控制方法等方面对国内外开发的780MPa级高强度抗震钢的进行了详细对比和分析,旨在为国内780MPa级高强度抗震建钢的开发提供参考,以满足中国高层建筑用钢的国产化需求。With the rapid development of super high-rise and large-span constructions, building steels were running into the way of high strength, high performance and large scale development. The anti-seismic performance for high strength steel became the focus one of the topics. The domestic and abroad 780 MPa class anti-seismic steels were compared from performance requirements, chemical composition design, process control to microstructure control in order to guide the development of domestic high strength earthquake resistance steels and meet the de- mand of the steel for high rise buildings.
