林磊(清華大學(xué)建筑設(shè)計研究院有限公司, 北京 100084)[摘要] 回顧了平板式筏板的不同設(shè)計方法,通過建立柱上板帶中部的平面應(yīng)力模型,區(qū)分了等厚平板式筏板及上/下柱帽平板式筏板的受力特點,并以此為依據(jù)提出上柱帽與下柱帽平板式筏板在計算中應(yīng)采取不同的計算方法。以某工程筏板基礎(chǔ)為例,說明采用本文建議方法計算有助于提高筏板設(shè)計的精度和經(jīng)濟(jì)性。[關(guān)鍵詞] 平板式筏板;柱帽;有限元中圖分類號:TU398.7 文獻(xiàn)標(biāo)識碼:A 文章編號:1002-848X(2012)12-0135-04Design proposals for flat plate rooting with column-capitalLin Lei(Architectural Design & Research Institute of Tsinghua University Co., Ltd., Beijing 100084, China)Abstract: Several methods of flat plate rooting design were reviewed. By analyzing a plane stress model with FEM through straight line between two columns, different mechanical characteristics between flat plate rooting with equal thickness and flat plate rooting with up or down column-capital were compared. Thus, it was raised as a point of view that different methods of calculation should be taken in calculating flat plate rooting with up or down column-capital. Taking a flat plate rooting design in a project for example, the accuracy and economy can be enhanced by applying the advised proposals.Keywords: flat plate rooting; column-capital; FEM作者簡介:林磊,高級工程師,Email: linlei@tsinghua.org.cn參考文獻(xiàn)[1]葉列平,趙作周. 混凝土結(jié)構(gòu)(下冊)[M]. 2版. 北京:清華大學(xué)出版社,2006.[2]陳育尹,陳家友.平板式筏基計算方法的改進(jìn)和簡化[J]. 建筑結(jié)構(gòu),2003,33(3):25-28.[3]林磊,王寒冰. 刀把形樓板受力特點及配筋建議[C]//金土木結(jié)構(gòu)軟件全國用戶大會CUC'10論文集. 上海,2010.[4]彭安寧,錢力航.《高層建筑箱形與筏形基礎(chǔ)技術(shù)規(guī)范》講座(二)[J]. 建筑結(jié)構(gòu),2000,30(7):65-69.[5]朱炳寅. 無梁樓蓋結(jié)構(gòu)計算方法的分析與思考[J]. 建筑結(jié)構(gòu),1999,29(8):26-28.
