The period, displacement ratio, story deflection and econotechnical target of this new system were researched and were contrasted with the normal frametube system. The results show that the RC dense rib grid frametube structure has a better property compared with the normal frametube structure, which proves this new building system can be applied in high intensity earthquake area. It can provide reference for similar projects in the future.Keywords:reinforced concrete; dense rib grid frametube; seismic behaviour; econotechnical target作者簡介:王其明,博士研究生, Email:wqmpass@163.com。參考文獻(xiàn)[1]馬克儉,高國富,張華剛,等.空間網(wǎng)格式框架結(jié)構(gòu)在多、高層大開間靈活劃分房間石膏節(jié)能建筑中的研究與應(yīng)用綜述[J].空間結(jié)構(gòu),2009,15(3):6784.[2]馬克儉,盧亞琴,張華剛,等.以磷石膏為模板的新型鋼筋混凝土結(jié)構(gòu)體系實驗研究[J].建筑結(jié)構(gòu)學(xué)報,2009,30(6):128133.[3]張華剛, 馬克儉, 盧亞琴,等. 以磷石膏為模板的密肋網(wǎng)格式框架小高層住宅結(jié)構(gòu)體系[J]. 貴州工業(yè)大學(xué)學(xué)報:自然科學(xué)版, 2008, 37(4):2832.[4]黃首赟. 以磷石膏為模板兼建筑輔材的鋼筋砼密肋井字大板與密肋網(wǎng)格板式剪力墻結(jié)構(gòu)體系的研究與應(yīng)用[D]. 貴陽: 貴州大學(xué), 2007.[5]盧亞琴,馬克儉,張華剛,等. 磷石膏墻體鋼筋混凝土網(wǎng)格式框架結(jié)構(gòu)動力反應(yīng)數(shù)值分析[J].建筑結(jié)構(gòu)學(xué)報,2009,30(S2):3640.
