（中國(guó)建筑科學(xué)研究院上海分院，上海200023）[摘要] 結(jié)構(gòu)分析中，梁剛度放大系數(shù)可采用不同的方法計(jì)算。本文針對(duì)梁剛度放大系數(shù)的不同計(jì)算方法進(jìn)行比較分析，研究了梁跨、板厚、梁高度對(duì)梁剛度放大系數(shù)的影響，并分析梁剛度放大系數(shù)對(duì)結(jié)構(gòu)整體指標(biāo)和構(gòu)件內(nèi)力配筋的影響。同時(shí)分析了不同樓板剛度假定下的梁剛度放大的正確應(yīng)用。[關(guān)鍵詞] 梁剛度放大系數(shù); 有效翼緣; 彈性板中圖分類(lèi)號(hào)：TU375.1 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2013)S1-0643-06Discussion on amplification factor for beam stiffnessZhu Wei, Huang Yiping, Qin Jingwei（Shanghai Branch, China Academy of Building Research, Shanghai 200023, China）Abstract: The stiffness amplification factor can adopt by different method in analysis of the structure. This paper analyzed and compared the different methods to calculate the amplification factor of beam stiffness, discuss the influence of beam span, plate thickness, beam height. Research the influence of the amplification factor of beam stiffness for structure, force and reinforcement for member. Meanwhile, analyzes the different influence of the assume for floor stiffness to amplification factor of beam stiffness.Keywords: amplification factor, effictive flange, elasticity plate作者簡(jiǎn)介：朱偉，教授級(jí)高工，Email:zhuwei@pkpm.com.cn。
