（化工部第四設(shè)計院 武漢 4300730[提要] 對《混凝土結(jié)構(gòu)設(shè)計規(guī)范》GBJ10 - 89的受彎構(gòu)件彎曲剛度公式進行推導(dǎo)化簡，得出矩形截面梁的短期剛度和長期剛度的實用計算公式，可供設(shè)計參考使用。
[關(guān)鍵詞] 鋼筋混凝土 受彎構(gòu)件 短期剛度 長期剛度 撓度By deducing and simplifying the formulas for structure elements subjected to bending in Code for Con-crete Structure Design(GBJl0 - 89), we obtain the applicable formulas for short-term rigidity and long-term rigidity calculation of rectangular section beam, which can work as references for design.
Keywords: bending element; short-term rigidity; long-term rigidity; deflection
