［摘要］介紹了超高層結(jié)構(gòu)去除次要構(gòu)件（SMR）、等效柱（WCA）、去除次要構(gòu)件與等效柱組合（SMR+WCA）和層模型（SM）四種簡(jiǎn)化分析方法，并編制了超高層結(jié)構(gòu)簡(jiǎn)化分析軟件。以一實(shí)際框架-核心筒超高層結(jié)構(gòu)為例，先分析對(duì)比了四種簡(jiǎn)化模型結(jié)構(gòu)的動(dòng)力特性、計(jì)算時(shí)間以及常遇地震作用、脈動(dòng)風(fēng)荷載作用下的結(jié)構(gòu)動(dòng)力響應(yīng)，再分析對(duì)比了含阻尼器的簡(jiǎn)化模型的結(jié)構(gòu)響應(yīng)。結(jié)果表明采用SMR+WCA簡(jiǎn)化模型的結(jié)構(gòu)精度高，計(jì)算速度快，性價(jià)比最高，為消能減震方案的確定節(jié)省了成本，有一定的工程意義。

Abstract:Four simplified analysis methods of super high-rise structures were introduced, including secondary member removed (SMR), wide-column analogy (WCA), combination of SMR and WCA and story model (SM) respectively, and simplified analysis software of super high-rise structures were implemented. A real project of super high-rise frame-corewall structure was taken as an example and four simplified model structure were analyzed and compared, including dynamic characteristics, computation time and dynamic response under frequent earthquakes and fluctuating wind loads. The structure responses of simplified structural model with dampers were compared. Results show that simplified model of combination of SMR and WCA has high precision, fast calculation and high performance price ratio. Simplified model can save cost in determination of energy-dissipation scheme, and it has certain significance in engineering application.

Keywords:simplified analysis; super high-rise structure; simplified accuracy; computation speed
