［摘要］通過對我國現(xiàn)行抗震設(shè)計(jì)方法的簡要概述，得出為了實(shí)現(xiàn)規(guī)范要求的鋼框架梁鉸倒塌機(jī)制，需要使用抗震性能好的鋼材。特別對鋼材屈強(qiáng)比的重要性作了重點(diǎn)闡述。為了在框架梁柱中能使用高強(qiáng)度、高屈強(qiáng)比的鋼材，提出了必須發(fā)展新的抗震結(jié)構(gòu)——控制震害結(jié)構(gòu)(DCS)的必要性。

Abstract:By summarizing domestic actual anti-seismic design method, steel of high-performance for anti-seismic is needed to achieve beam plastic hinge collapse mechanism which is required in the code. The steel of high-performance for anti-seismic is the steel that meet the four basic requirements. It highlights the importance of steel yield ratio. To put steel of high strength and high yield-strength ratio into use for columns and beams in frame structure, necessity of developing new anti-seismic structural style, such as damage-controlled structures (DCS), is provided.
Keywords:β spectrum; earthquake resistant capability; beam plastic hinge collapse mechanism; yield-strength ratio; plastic deformation; damage-controlled structures
