[摘要] 在剪力墻結(jié)構(gòu)設(shè)計(jì)中經(jīng)常遇到連梁超筋而將其設(shè)置成雙連梁，結(jié)構(gòu)分析時(shí)通常把雙連梁等效成單連梁再進(jìn)行計(jì)算。根據(jù)兩者轉(zhuǎn)角剛度等效剛度應(yīng)相等的原理，提出轉(zhuǎn)角剛度等效雙連梁等效方法并推導(dǎo)出轉(zhuǎn)角等效公式,利用有限元方法驗(yàn)證了其正確性與優(yōu)越性，為實(shí)際工程設(shè)計(jì)提供了技術(shù)支持。[關(guān)鍵詞] 連梁超筋; 雙連梁; 轉(zhuǎn)角剛度等效; 剪壓比中圖分類號(hào)：TU223 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2013)S2-0426-04作者簡介：姜忻良，教授，博導(dǎo)，Email: jiangxinliang@126.com；宣波， 碩士研究生，Email: xuanbo77@163.com 。The method of the angular stiffness equivalent of double coupling beam in the shear wall structureJiang Xinliang , Xuan Bo(School of Civil Engineering Tianjin University, Tianjin 300072, China, )Abstract: The problem of over-reinforced coupling beam often encountered in the design of the shear wall structure and common solutions is setting it to double coupling beam, When carry on the structure analysis usually the double coupling beam is transformed into an equivalent single coupling beam to calculate. Based on the principle of angular stiffness equivalent,double coupling beam angular stiffness equivalent method was put forward and angular equivalent formula was deduced. Its correctness and superiority was validated by finite element method, provides the technical support for practical engineering design.Keywords: over-reinforced coupling beam; double coupling beam; angular stiffness; shear compression ratio
