［摘要］《門式剛架輕型房屋鋼結(jié)構(gòu)技術(shù)規(guī)程》(CECS102：2002)應(yīng)用到現(xiàn)在，已漸漸暴露出一些不妥之處。結(jié)合上海市《輕型鋼結(jié)構(gòu)技術(shù)規(guī)程》的編制工作，比較了國內(nèi)外規(guī)范關(guān)于工字形截面有效面積的計算規(guī)定，采用有限元方法進行數(shù)值分析，指出了現(xiàn)行門式剛架規(guī)程的不合理之處，提出了腹板有效寬度的修改意見。

Abstract:Technical Specification for Steel Structure of Light-weight Buildings with Gabled Frames (CECS102: 2002) has been used for several years and exposed some defects. Prepared for the edit of Technical Specification for Light Weight Steel Building Systems of Shanghai, calculation of effective area of H-section according to different codes of our country and others was compared, and numerical analysis by finite element method was carried out. Unsuitable rules of Code CECS102: 2002 were pointed out, and the suggestions for amendment of the effective width of the web were given.
Keywords:gabled frames; H-section; effective width; design codes; finite element analysis; proposed formula
