[提要] 在試驗(yàn)與理論研究的基礎(chǔ)上,對(duì)24棟異型柱框-桁架結(jié)構(gòu)與異型柱框架結(jié)構(gòu)抗震性能進(jìn)行了對(duì)比研究,討論了不同框-桁架選型對(duì)異型柱框-桁架剛度及地震反應(yīng)的影響,提出了可供工程設(shè)計(jì)參考的建議。
[關(guān)鍵詞] 混凝土 框-桁架結(jié)構(gòu) 異型柱 抗震分析On the basis of experimental research and theoretic analysis, the aseismic behaviour of 24 structures of frame and frame-truss with special-shaped columns is compared. The effects of frame-truss with different special-shaped columns on lateral stiffness and reaction of earthquake are discussed. Some advices for engineering design are suggested.
Keywords: R.C.frame-truss; special-shaped columns; earthquake resistant behaviour
