［摘要］基于纖維模型理論，利用PERFORM-3D軟件實(shí)現(xiàn)了復(fù)雜超高層建筑結(jié)構(gòu)的彈塑性時(shí)程分析并進(jìn)行構(gòu)件變形性能評(píng)估。針對(duì)PERFORM-3D建立高層結(jié)構(gòu)模型的復(fù)雜性，開發(fā)了其前處理程序ETP，使之能夠方便準(zhǔn)確地建立彈塑性模型。分析表明，基于纖維模型的整體結(jié)構(gòu)彈塑性分析法高效可行，不但宏觀上可得到結(jié)構(gòu)整體響應(yīng)，而且微觀上可得到構(gòu)件的內(nèi)力及變形和纖維的應(yīng)力及應(yīng)變。通過工程實(shí)例，得到整體結(jié)構(gòu)響應(yīng)、構(gòu)件的變形及結(jié)構(gòu)能量耗散情況，可用于研究按我國(guó)現(xiàn)行規(guī)范設(shè)計(jì)的超高層混凝土結(jié)構(gòu)在罕遇地震作用下的非線性變形及受力特點(diǎn)。

Abstract:Elasto-plastic time-history analysis and component deformation performance evaluation of complex super high-rise building structure can be realized by the program PERFORM-3D based on the theory of fiber model. In order to reduce the complexity of tall building structure modeling, a pre-processing program named ETP was proposed. The research showed that elasto-plastic analysis of the whole structure based on fiber model was an efficient and successful method. In macro sense, the response of the whole structure can be gained. And in micro sense, component internal force and deformation as well as the stress and strain of the fiber can be gained. Combining with an engineering example, the results of the whole structure response, component deformation and energy dissipation can be used for the research of the elasto-plastic deformation and stress characteristics of the super high-rise building structure designed according to current codes under rare earthquake.

Keywords:elasto-plastic time-history analysis; PERFORM-3D; super high-rise building structure; performance-based
