(廣州市城市規(guī)劃勘測(cè)設(shè)計(jì)研究院, 廣州 510060)[摘要]某雙塔樓超高層結(jié)構(gòu)總高度為186.3m,因平面超長(zhǎng)產(chǎn)生較大的扭轉(zhuǎn)效應(yīng),進(jìn)而影響整個(gè)結(jié)構(gòu)的抗震性能。通過設(shè)置防震縫,將其分成B級(jí)、超B級(jí)高度的兩個(gè)超限高層,采用鋼筋混凝土框架-核心筒結(jié)構(gòu)。根據(jù)結(jié)構(gòu)動(dòng)力彈塑性時(shí)程計(jì)算分析,并融入性能化設(shè)計(jì)思想,采取必要的加強(qiáng)措施,同時(shí),通過1∶30比例振動(dòng)臺(tái)試驗(yàn)進(jìn)行驗(yàn)證,確保整個(gè)結(jié)構(gòu)滿足“中震可修、大震不倒”的抗震設(shè)防目標(biāo)。[關(guān)鍵詞]超高層建筑; 防震縫; 動(dòng)力彈塑性時(shí)程分析; 振動(dòng)臺(tái)試驗(yàn)中圖分類號(hào):TU318,TU973 文獻(xiàn)標(biāo)識(shí)碼:A 文章編號(hào):1002-848X(2013)23-0038-04Structural design of the twin towers high-rise building with seismic jointsTang Min, Chen Weijun, Liu Yang, Su Yantao, Chen Chen(Guangzhou Urban Planning & Design Survey Research Institute, Guangzhou 510060, China)Abstract: The total height of the twin towers high-rise structure is 186.3m, due to the super long plane and large torsional effects, the seismic performance of the whole structure will be affected. By setting the seismic joints, the building was divided into two high-rise structures with Class B, super Class B respectively. Reinforced concrete frame-core wall structure was adopted. According to the structural dynamic elastic-plastic time-history analysis, performance-based design, strengthening seismic fortification measures for necessary, and shaking table test on 1∶30 model, the whole building can be ensured to meet the “moderate seismic fortification goal of repair, not collapse under rare earthquake”.Keywords: super high-rise building; seismic joint; dynamic inelastic time history analysis; shaking table test作者簡(jiǎn)介:唐珉,碩士,高級(jí)工程師,一級(jí)注冊(cè)結(jié)構(gòu)工程師,Email:gz2017@163.com。參考文獻(xiàn)[1]習(xí)朝位,蔣義平,佟道林,等. 大底盤雙塔樓連體結(jié)構(gòu)抗震試驗(yàn)研究[J]. 建筑結(jié)構(gòu),2009,39(5):102-107.[2]GB 50010—2002混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)范[S]. 北京:中國(guó)建筑工業(yè)出版社,2002.[3]JGJ 3—2002高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程[S]. 北京:中國(guó)建筑工業(yè)出版社,2002.[4]GB 50011—2001建筑抗震設(shè)計(jì)規(guī)范[S]. 2008年版. 北京:中國(guó)建筑工業(yè)出版社,2008.[5]張敏,張杜,袁雪芬,等. 西交利物浦大學(xué)行政信息樓關(guān)鍵構(gòu)件設(shè)計(jì)[J]. 建筑結(jié)構(gòu),2012,42(1):12-15.[6]楊學(xué)林,益德清. 多塔樓高層結(jié)構(gòu)振動(dòng)特性與抗震設(shè)計(jì)[J]. 工程力學(xué),2001,18(2):76-81.[7]范立礎(chǔ),聶利英,李建中. 復(fù)雜結(jié)構(gòu)地震波輸入最不利方向標(biāo)準(zhǔn)問題[J]. 同濟(jì)大學(xué)學(xué)報(bào):自然科學(xué)版,2003,31(6): 631-636.
