[摘要] 鋼結(jié)構(gòu)直接加層形成的混合結(jié)構(gòu)在分析設(shè)計(jì)上尚無(wú)統(tǒng)一的規(guī)范標(biāo)準(zhǔn)可循，導(dǎo)致各地鋼結(jié)構(gòu)加層工作采用的方法很不一致。結(jié)合鋼結(jié)構(gòu)加層質(zhì)量和剛度突變特點(diǎn)，討論了鋼結(jié)構(gòu)加層中存在的整體抗震分析、阻尼修正、年限統(tǒng)一和規(guī)范選擇問(wèn)題，總結(jié)了一套較為合理的分析設(shè)計(jì)方法以供參考。

Abstract: Because of lacking of a universal standard criterion on analysis and design for the composite structure, which formed by the direct storey-adding method with steel structure, there are a variety of methods around the work of the storey-adding. Based on the mass and stiffness mutation feature of the composite structure, the questions about seismic analysis, damping correction, the unity oflife and standard choice were discussed. Finally,a set of relatively reasonable analysis and design method for reference was summarized.
Keywords: steel structure; storey-adding; seismic analysis; standard choice
