(西安建筑科技大學土木工程學院，西安710055)［摘要］《砌體結構設計規(guī)范》(GB50003—2001)建議的連續(xù)墻梁內力計算方法較繁瑣，不便于設計人員應用。通過2~5跨連續(xù)墻梁的有限元分析，根據(jù)其應力和內力分布規(guī)律，采用一定的簡化假定，建立了基于一般連續(xù)梁內力分析方法的墻梁內力近似計算公式。將公式計算值與現(xiàn)行規(guī)范公式的計算值進行了比較，并通過實例分析，對不同設計方法所得配筋量進行了對比。［關鍵詞］連續(xù)墻梁；有限元分析；簡化公式中圖分類號：TU365文獻標識碼：A文章編號：1002-848X(2011)02-0085-04Finite element analysis and simplified calculating formulas of continuous wall-beamsTao Rongjie, Liang Xingwen, Wang Qinglin(College of Civil Engineering, Xian University of Architecture and Technology, Xian 710055, China)Abstract:The design regulations of continuous wall-beams in Code for design of masonry structures GB50003—2001 is too complex to be used by engineers. The finite element analysis of 2~5 span continuous wall-beams were carried out. For inner forces of beam and simplified assumptions, the approximate calculation formulas of bearing capacity for the continuous wall-beams was presented，which was based on the analysis method of continuous beams. The calculation values were compared with the code results. The calculated example and the comparison between this method and others were given.Keywords:continuous wall-beams; finite element analysis; simplified calculating formulas*《砌體結構設計規(guī)范》基金項目。作者簡介：陶榮杰，碩士，Email：tao_rongjie@yahoo.com.cn。參考文獻［1］GB50003—2001砌體結構設計規(guī)范［S］. 北京: 中國建筑工業(yè)出版社，2001.［2］龔紹熙，李翔，張曄，等. 連續(xù)墻梁的試驗研究、有限元分析和承載力計算［J］. 建筑結構，2001，31(9)：7-11.［3］李曉文，王慶霖，梁興文. 豎向荷載作用下連續(xù)墻梁設計［J］. 建筑結構，2001，31(9)：3-6.［4］張國軍，劉伯權，齊小紅，等. 連續(xù)墻梁水平及豎直截面應力的分布規(guī)律［J］. 建筑結構，2003，33(6)：66-68.［5］孟達，曹輝，杭英. 豎向均布荷載作用下開洞連續(xù)墻梁的有限元分析［J］. 工業(yè)建筑，2006，36(11)：59-61.［6］唐岱新. 砌體結構設計規(guī)范理解與應用［M］. 北京:中國建筑工業(yè)出版社，2002.
